How to Buy Custom Plastic Packaging Containers

ustom plastic packaging container

What is Plastic Packaging Containers

Plastic packaging containers are containers that are used to hold something; whether that be food, clothing, or anything else; that are made out of plastic. Many companies use different plastic packaging containers, such as pharmaceutical companies. the food industry, the healthcare industry, the pet industry, and many others.

Plastic packaging containers can be found at most stores you shop at, but what about custom plastic packaging containers? Where would you find an odd-shaped container that you need for a specific project? What if you need 1000 of that same odd-shaped container for your business? Do you want your company logo on those containers? There are many aspects to look at when choosing containers, depending on what you are looking for. For example, if you are looking for clear plastic packaging containers for food, you wouldn’t want containers that contain BPA. go to custom plastic food storage containers pageto know more information.

Step to order your own Plastic Packaging Containers

The first step in ordering your custom plastic packaging containers would be to determine the size and shape of the container that you need. If you need a smaller container, or a basic plastic mold then you are looking at spending less money. Whereas if you are wanting a plastic packaging container in an odd shape, you will be spending a little more.
Next, you would determine what quality of plastic you need the containers to be. You would need to look at different aspects for this, such as what products are going in the containers, how the custom plastic packaging containers are going to be stored, and what climate the containers will be stored in. This is an important step because you don’t want to order a container that is not going to fit your specific needs.
After you have determined the size, shape, and quality of your plastic packaging container, you will need to decide what you want the product to look like. This means deciding whether you want custom colors or extra design. Then, you will need to determine how many containers you need. If you need the containers for a wedding, for example, you wouldn’t need as many as you would for a business that needs containers for a product. all of those process we called part design and delvelopment.
In addition, you would determine how quickly you need the product. If you need a custom product as soon as possible, you would want to look at companies with in house engineers, that are located in your country. However, if you can wait some time, you could be saving money if you went for a larger manufacture overseas, like finf a plastic molding company to handle your custom plastic mold and massive products production.
Furthermore, you will need to decide whether you need a label on the containers. This is a pretty simple step, but if it’s missed, you could end up with thousands of containers that were ordered incorrectly.
Finally, you would choose the business that you want to order from, let them know your vision, and wait for your arrival. Choosing a business can be a difficult decision, and can be time consuming because you don’t want to make a mistake when mass producing something important. As long as you follow these steps, you are headed in the right direction to getting the custom plastic packaging containers you need.

Plastic Food Storage Containers utility

Most of us have a microwave in-house, that’s why choosing plastic food containers that can be used safely in the microwave is very important. Be sure to read the product description before you make the buying decision. You should also select the containers that can be washed with dishwasher as well as can be used safely in the freezer, refrigerator.

One of the most important features of custom plastic food storage containers is the ability to isolate the food completely from the outside environment. If your container is not hermetic, the odour from inside can leak and absorb into other foods. This is, in turn, will make other foods lose their quality.

One more tip that you should keep in mind when choosing plastic food storage containers is always going for the ones that have a clear colour. Don’t be trapped by the colourful items. They may be made from recycled plastic that will do more harm than good to your health. You can also smell the containers to know roughly the quality of the plastic food storage containers. Good containers will have little to no odour while items which were made from recycled plastic will have strange, unpleasant smells.

Glass food storage containers utility

For some people, glass food storage containers are their personal favourite as many features that no other types of food containers can have. Glass food storage containers don’t turn opaque over time, glass doesn’t absorb odour. In addition, the glass container is very safe. You don’t have to worry about unethical manufacturers use low-quality material to make the product as in plastic containers. Such benefits explain why while plastic food storage containers are so popular, glass food containers still have a good place in the market.

plastic food containersWhen choosing glass food containers, you need to select good brands. After that, you should focus on durability. As a matter of fact, glass can easily be broken, this will be very dangerous. However, with the development of material industry, there are now many glass containers have great durability, but compare to plastic food storage containers, plastic food box is still more convenient and safer than glass container, and you will never get broken, this is the main reason that is why plastics food box has more market then glass food containers,

Plastic Injection Tooling Manufacturing

plastic mold technology

Creating properly parts design and built plastic injection tooling is the most important part of any injection molded parts development. In order to build a successful high-quality plastic injection mold tooling, a comprehensive plan must be followed.

Plastic Injection Tooling Design 

If a plastic injection tooling is designed incorrectly, the penalty may be paid in part quality, injection molding tool repair costs, or longer cycle time (higher component cost) for the entire length of production needs. Because of this we focus on injection tooling design with production in mind and specify parameters up front so that design specification errors or omissions never enter into the quality/cost equation.Plastic Injection Tooling

Moldflow Analysis

we do Moldflow filling analysis during plastic injection tooling design & development to assure proper plastic flow through the tool and answer questions such as sprue size, runner size, gate size, gate position, number of gates, plastic shear level, tonnage required, weld line locations, potential air traps (potential burn marks), sink marks issue, filling time, and a host of other important issues must be analyzed before any steel is cut. This analysis is completed in the tool design phase to eliminate costly tool or part design problems that might otherwise go unnoticed until it is too late.

Plastic injection Tooling Cost

There is a wide range of parts from the very simple to the very complex with a range low to very high production volume requirements. Likewise, there are many levels of plastic tooling manufacturing companies with varying levels of overhead and capability. If a mold tool is built by a plastic tooling company with a capability level or overhead level that is above what is needed, plastic tooling cost can exceed the level that would allow a project to go forward. Likewise, if the plastic tooling company does not have capabilities needed for a complex mold, quality, price, or delivery time could suffer. This is why plastic tooling complexity must be matched with toolmaker size and capability.

We are a professional plastic tooling company in China, we make injection molding tools from small to big up to 30 tonnages, we have full plastic tooling manufacturing equipment to do all of mold manufacturing jobs in-house, this will be easy to control the lead time and quaintly of plastic injection tooling, plastic tooling we make are export to Canada, Germany, American and more country in America and Europe, The tooling components for plastic tooling can be matched correctly base on customers requirement, for Europe export plastic tooling we use HASCO tooling components, for American customers we use DME tooling components, so customers can replace any tooling components easy and fast.

Plastic Injection Tooling Warranty

We appreciate our customer’s investment and we stand by our plastic tooling. Any injection moulding tooling developed through our mold factory will have lifetime shots guarantee, plastic toolings made by our factory normally have 3 types of shots guarantee.

1. Minimum of one million lifetime shots guarantee. For this type of plastic injection tooling, we use hardened steel for cavity and core, like S136,1.2344, H13, 1.2083, 1.2343, etc, the hardness of steel is HRC 48-52,

2. Minimum of a half million-lifetime shots. For this type of plastic injection mold tooling, we use pre-hardened steel material, such as 1.2738H, P20, 1.2738HH, etc, the hardness for this injection mold tooling is HRC 33-38.

For export injection moulding tool, all of the cavity/core steel is bought from LKM (the biggest mold steel company in China), or buying the steel in Europe brand according to customer requirement.Plastic Tooling Company

3. The above two types of plastic injection tooling are for export tooling, this one is for the none export injection moulding tool, which means we will produce the plastic molded parts for the customer and ship the plastic parts to our customers, the mold tooling lifetime for this type of tooling will be no limited (as many as customer wants), the reason because we have the plastic tooling in-house, if any issue happened we can fix the tooling for our customer with no extra cost.

Moreover, if customer want us to produce the injection molding parts for them, the plastic tooling cost will be very lower, because we will never earn any profits on the injection moulding tool manufacturing, or even we can bear come plastic tooling cost, this is depending on the number of parts customer requirement, this is the best options for you to increase your market by minimum investment.

This is not the end if you choose the number three option, when you have finished number of parts production, we can return all of the injection moulding tool prices back to you, you can use this price to order plastic injection molded parts directly, of course, this is depending on the quantity of the parts you have been produced. If you want to know more about this solution? You are welcome to contact us or send your requirement for quotation, you will have our professional team to support, we offer you the best price and solution for your project, and we never share your data to any others.

What is Home Appliance Mold

Home appliance mold refers to a mold or tool used in the manufacturing process of home appliances. In the context of manufacturing, a plastic mold is a hollow form typically made of steel (1.2344, 1.2343, H13 etc.), stainless steel or aluminum, and it is used to shape and form materials like plastic, glass, or metal into the desired shape of a specific product.

In the case of home appliances, Home Appliance Molds are commonly used in the production of components and parts. Home appliances can include a wide range of products such as refrigerators, washing machines, ovens, microwaves, and more. The Home Appliance Mold is a crucial component in the injection molding or casting process, allowing manufacturers to mass-produce consistent and precise parts for these appliances.

The home appliance mold is designed to create the specific shapes and features required for each part of the appliance. It is an essential tool in the manufacturing industry, helping to ensure efficiency, accuracy, and uniformity in the production of home appliances.

Types of Home Appliance Mold

There are various types of molds used in the production of home appliances, depending on the manufacturing process and the materials involved. Here are some common types of home appliance molds:

  1. Injection Molds: Injection molding is a widely used process in home appliance manufacturing. It involves injecting molten material, often plastic, into a mold cavity. Injection molds are typically made of steel or aluminum and are designed to withstand high pressure and temperatures.
  2. Blow Molds: This type of mold is used in the blow molding process, which is common for manufacturing hollow parts of appliances such as plastic bottles or containers. The material is heated and inflated to the shape of the mold.
  3. Compression Molds: Compression molding is used for materials like rubber or thermosetting plastics. The mold is closed, and the material is compressed and heated to take the shape of the mold.
  4. Extrusion Dies: In some cases, appliances have components that are made through extrusion, where material is forced through a die to create a continuous shape. Extrusion dies are used in this process.
  5. Thermoforming Molds: Thermoforming is a process where a plastic sheet is heated and formed over a mold. This is commonly used for manufacturing appliance components with large, flat surfaces.
  6. Rotational Molds: This type of mold is used in rotational molding, where a mold is rotated bi-axially while being heated. The material, often plastic in powder form, coats the interior of the mold and solidifies into the desired shape.

The choice of mold depends on factors such as the type of material being used, the complexity of the part, production volume, and cost considerations. Manufacturers select the most suitable mold type for their specific production requirements.Home appliance mold

Advantages of Home Appliance Mold

The use of home appliance molds in the manufacturing process offers several advantages, contributing to the efficiency, precision, and cost-effectiveness of production. Some of the key advantages include:

  1. Precision and Consistency: Molds are designed with precision to produce identical components or parts consistently. This ensures uniformity in the quality of the manufactured home appliances.
  2. High Production Efficiency: Molds allow for mass production of components at a high rate. The automation of the molding process can significantly increase production efficiency, reducing the time it takes to manufacture each part.
  3. Cost-Effective Production: Once the initial investment in mold fabrication is made, the cost per unit decreases with higher production volumes. This cost-effectiveness makes molds a preferred choice for large-scale manufacturing.
  4. Complex Geometries: Molds enable the production of intricate and complex shapes that may be challenging or impossible to achieve through other manufacturing methods. This is particularly important for designing modern and aesthetically pleasing home appliances.
  5. Material Savings: Molds are designed to use materials efficiently, minimizing waste during the manufacturing process. This is especially important in industries where material costs are a significant factor.
  6. Quick Turnaround: The use of molds allows for rapid production cycles, contributing to a quick turnaround time for manufacturing home appliances. This can be crucial in meeting market demands and adapting to changing consumer preferences.
  7. Durability and Longevity: Well-made molds, typically constructed from durable materials like steel or aluminum, can withstand the harsh conditions of the molding process, contributing to their longevity and repeated use.
  8. Customization: Molds can be customized to produce a wide variety of shapes and sizes, allowing manufacturers to create diverse product lines and meet specific customer requirements.
  9. Reduced Labor Costs: Automation of the molding process can lead to reduced labor costs, as the need for manual intervention is minimized. This can contribute to overall cost savings in the production of home appliances.
  10. Scalability: The use of molds facilitates the scalability of production. Manufacturers can easily scale up or down based on market demands without significant changes to the manufacturing process.

Despite these advantages, it’s important to note that the initial design and fabrication of molds can be expensive and time-consuming. The choice of the right type of mold and material considerations must be carefully evaluated to optimize the benefits of using molds in home appliance manufacturing.

Not only Home Appliance Mold Industrial But Molds are also the foundation of all industrial, nowadays, electronics, automotive, electric machine, electrical appliance, instrument, home appliance, communication, military work and other products,70%-80% of the products, all rely on injection molding. With the injection molding forming the spare parts has shown high accuracy, high complexity, high consistency, high efficiency and low cost, which is the other manufacturing way are not able to match. plastic Mould determine the quality of product, efficiency and development capability at most

At present, China is the largest producing base of the home appliance, and the production continues to expand.

Present, evolved from the Wall Street turmoil, worsening global economic situation is intensified, market consumption among this into a new winter season

It brings huge needs of raw material. According to the data announced by China Electrical Home Appliance Association, the major home appliance production cost more than 6.7 million tons of steel material. The amount of nonferrous metal and engineering plastic went to more than 1 million tons individually. So the demand for machine and mould is very big at the same time. For the home appliance industry, developing a refrigerator required 160-210 sets of injection mould, an air conditioner require about 40 sets, a washing machine need about 50 sets of the injection mould.

Residual Stress

Electronic Injection Molded part

A culprit in shrinkage and warpage problems

Residual stress is process-induced stress, frozen in molded plastic parts. It can be either flow-induced or thermal-induced. Residual stresses affect a part similarly to externally applied stresses. If they are strong enough to overcome the structural integrity of the part, the part will warp upon ejection, or later crack, when external service load is applied. Residual stresses are the main cause of part shrinkage and warpage. The process conditions and design elements that reduce shear stress during cavity filling will help to reduce flow-induced residual stress. Likewise, those that promote sufficient packing and uniform mold cooling will reduce thermal-induced residual stress. For fibre-filled materials, those process conditions that promote uniform mechanical properties will reduce thermal-induced residual stress.

Flow-induced residual stress

Unstressed, long-chain polymer molecules tend to conform to a random-coil state of equilibrium at temperatures higher than the melt temperature (i.e., in a molten state). During processing the molecules orient in the direction of flow, as the polymer is sheared and elongated. If solidification occurs before the polymer molecules are fully relaxed to their state of equilibrium, molecular orientation is locked within the molded plastic part. This type of frozen-in stressed state is often referred to as flow-induced residual stress. Because of the stretched molecular orientation in the direction of flow, it introduces anisotropic, non-uniform shrinkage and mechanical properties in the directions parallel and perpendicular to the direction of flow.

Residual Stress

Deformation issue

Frozen-in molecular orientation

Due to a combination of high shear stress and a high cooling rate adjacent to the mold wall, there is a highly oriented layer frozen immediately below the part surface. This is illustrated in Figure 1. Subsequent exposure of a part with high residual flow stresses (or frozen-in orientation) to high temperature may allow some of the stresses to relieve. This typically results in part shrinkage and warpage. Due to the thermal insulating effect of the frozen layers, polymer melt in the hot core is able to relax to a higher degree, leading to a low molecular orientation zone. China mold supplier

FIGURE 1. The development of residual flow stresses due to frozen-in molecular orientation during the filling and packing stages.
(1) High cooling, shear, and orientation zone

(2) Low cooling, shear, and orientation zone

Reducing flow-induced residual stress

Process conditions that reduce the shear stress in the melt will reduce the level of flow-induced residual stresses. In general, flow-induced residual stress is one order of magnitude smaller than the thermal-induced residual stress.

  • higher melt temperature
  • higher mold-wall temperature
  • longer fill time (lower melt velocity)
  • decreased packing pressure
  • shorter flow path.

 Thermal-induced residual stress

Thermal-induced residual stress occurs due to the following reasons:

  • The material shrinks as the temperature drops from the process settings to the ambient conditions reached when the process is complete.
  • The material elements experience different thermal-mechanical histories (e.g., different cooling rates and packing pressures) as the material solidifies from the mold wall to the center.
  • Changing pressure, temperature, and molecular and fiber orientation result in variable density and mechanical properties.
  • Certain mold constraints prevent the molded part from shrinking in the planar directions.

Free quenching example

Material shrinkage during injection molding can be conveniently demonstrated with a free quenching example, in which a part of the uniform temperature is suddenly sandwiched by cold runner mold walls. During early cooling stages, when the external surface layers cool and start to shrink, the bulk of the polymer at the hot core is still molten and free to contract. However, as the internal core cools, local thermal contraction is constrained by the already-rigid external layers. This results in a typical state of stress distribution with tension in the core balanced by compression in the outer layers, as illustrated in Figure 2 below.

Variable residual stresses arise and the part deforms as layers of different frozen-in specific volume interact with each other

Process-induced vs. in-cavity residual stress

Process-induced residual stress data are much more useful than in-cavity residual stress data for molding simulation. Following are definitions of the two terms, along with an example that illustrates the difference between them.

Process-induced residual stress

After part ejection, the constraints from the mold cavity are released, and the part is free to shrink and deform. After it settles to an equilibrium state, the remaining stress inside the part is called process-induced residual stress, or simply, residual stress. Process-induced residual stress can be flow-induced or thermal-induced, with the latter being the dominant component.

In-cavity residual stress

While the part is still constrained in the mold cavity, the internal stress that accumulates during solidification is referred to as in-cavity residual stress. This in-cavity residual stress is the force that drives post-ejection part shrinkage and warpage.

Example

The shrinkage distribution described in Warpage due to differential shrinkage leads to a thermal-induced residual stress profile for an ejected part, as shown in the lower-left figure below. The stress profile in the upper-left figure is the in-cavity residual stress, in which the molded part remains constrained within the mold prior to ejection. Once the part is ejected and the constrained force from the mold is released, the part will shrink and warp to release the built-in residual stress (generally tensile stress, as shown) and reach an equilibrium state. The equilibrium state means that there is no external force exerting on the part and the tensile and compressive stresses over the part cross-section should balance with each other. The figures on the right side correspond to the case with a non-uniform cooling across the part thickness and, thereby, causing an asymmetric residual-stress distribution.

In-cavity residual stress profile (top) vs. process-induced residual stress profile and part shape after ejection (bottom).

Reducing thermal-induced residual stress

Conditions that lead to sufficient packing and more uniform mold-wall temperatures will reduce the thermal-induced residual stresses. These include:
–  Proper packing pressure and duration
–   Uniform cooling of all surfaces of the part
–  Uniform wall-section thickness

Injection Blow Moulding

Blow molding bottles

What Is Injection Blow Molding

Injection blow moulding is basically a series of processes involved in making hollowed plastic molding products and components. this injection blow molding process is one of the best molding processes for thin wall plastic molding containers. The three major processes are;

(1) Injecting a parison or thermoplastic into a blow mold to create a perform pipe at first (parison).

(2) Moving the perform pipe to blow mold and blowing the thermoplastic into a mold’s cavity to form a hollow molding part,

(3) Ejecting the final product. A wide range of hollowed injection molding products can be achieved through this method such as plastic bottles,Injection Blow Moulding

Blow Molding Materials.
Raw thermoplastic materials are easily utilized within the blow-molding process when they come in the form of small granules or pallets, which are melted first and molded into a hollow tube(parison). There is a wide range of thermoplastic materials that can be used but the ones that are easy to make
Polyvinyl chloride (PVC).
Polythene Terephtalate (PET).
High and low-density polyethylene (HDPE) and (LDPE) respectively.

Injection Blow Moulding Process.

There are 3 unique steps or processes involved during creating blow molded parts, they include;

Stretch-Blowing Mold.

This process is purposely used to produce hollowed objects having bi-axial molecular orientation. This is important as the specific molecular orientation provides clarity, acts as a perfect gas barrier and provides enhanced physical properties needed in storing carbonated beverages or chemicals.
The process is further subdivided into two distinct molding techniques. The one stage process requires the preform to be injected into the mold having properly conditioned temperatures and blown into the required containers—all under one continuous process. This method is effective where large production is not a priority.

The two-stage process: The preform is injected into the mold, where it is left for about 1 to 4 days and thereafter blown into containers. A re-heat blow(RHB) is a machine is used in this case. Typically, this process is costly compared to the one process technique but it is the best in mass production, for example, carbonated-beverage bottles.

Injection blow molding

The hot thermoplastic material is indexed and blowing into the mold while still on the pin. The bottle formed for instance is left to cool. It is then indexed and ejected at the next station. This stage or process allows neck finishing and threading at the mouth. The process is less concerned with the orientation enabling attaining more physical properties of the products.

Extrusion blow molding

This blow molding process commences with the conservation of an extruded prison tube. The prison is extruded between 2 halves of opened blow molds. Once the right length is attained, the molds close, holding the neck-end wide open while the bottom end is pinched and closed. A rod of the right diameter is then inserted on the neck end, while the poison is still hot to form the necessary threads. The molded bottle is then removed and excess material is trimmed from the pinch-off area at the bottom and neck areas.

FINAL VERDICT.

This method is not only economical but also popular because it is known to produce high-quality holloed parts and products. If you want to produce rigid walled bottles or pipes, then this the method for you.

plastic injection molds

What is a plastic injection mold?

A plastic injection mold is made of metal steel that has been made with a hollow base apart, as sharp as you want, and later filled with a liquid or any other material that can be used to make your plastic products, which will last millions of cycles. Some of the materials that can be poured into the hollow space of the steel include plastic, metal, glass, and even ceramic materials. The liquid is allowed to solidify, and the block is broken to retrieve the mold that has acquired the shape of the block. A plastic mold is a custom mold that is used for making custom injection molding parts.

 

Plastic mold technology

Plastic mold technology is by far the most popular method to manufacture plastic parts in the world today. This process is used for everything from inexpensive commercial plastic products, like disposable eating utensils and toys, to severe environments and highly stressed technical components, like critical parts for the automotive and aerospace industries.

You’ll find extensive use of injection-molded plastic parts in the electronics world for things like enclosures for cell phones, computers, televisions, and the like, as well as in the medical world, where things like syringe bodies, breathing apparatus, and a wide range of other life-saving devices are employed. No other process has come to dominate modern manufacturing as much as plastic molding, and its use increases every year.

Recently, critical steering components for General Motors cars and trucks were changed from stamped and machined steel parts to a plastic-molded assembly, resulting in a lighter part at a lower cost, quieter, and more reliable.

What is Plastic Injection Molding

Plastic injection molding or injection molding is the process of heating thermoplastic resin to a liquid, then shooting it under high pressure into a mold cavity that is the negative image of the desired part, allowing it to cool, and then opening the mold to allow the completed part to be ejected out of the mold.

In most cases, features can be built into the plastic mold cavity to give the part everything it will need when finished so that no other operations are needed once the part comes out of the mold. Textures, or high polishes, markings, screw holes, lens shapes, and any other features needed in the finished part can be built into the mold, so the finished part automatically has these features incorporated.

The advantages of plastic molding

The beauty of plastic molding is that many parts, even millions, can be made in exactly the same way and will come out the same no matter what. Each piece will have identical features, the same dimensions, and the same physical properties. It is the ideal way to make high volumes because of this consistency. Properly maintained, injection molds can last decades, making millions of parts per year. Properly set up and controlled, the 20 millionth part will be identical to the first part in every measurable way. No other manufacturing process has the potential to operate at this level of consistency.

Multiple cavities of each part can be built into the plastic injection mold tool, so that each time the mold opens, you can make 16 or 32 or 48 or some other multiple of parts for each cycle of the injection molding machine to really increase the production rate and greatly decrease the cost of making a part.

In some cases, several different parts—for instance, a right- and left-hand version of an enclosure—can be made in a single mold to reduce the number of machine cycles required to make multiple parts of an assembly, increasing production and lowering the injection molding cost. Injection molding also offers flexibility not possible with any of the other manufacturing processes.

Injection molding also offers one of the lowest scrap rates of any other manufacturing process as well. Since no second operation is generally required, no material is cut off and thrown away. It is possible to use a special technique to completely eliminate even the small pathways the plastic flows through to cut the material scrap rate to virtually zero, or often, any plastic removed in the process can be reused by pelletizing it and mixing it back into the fresh plastic resin in closely controlled proportions. These capabilities mean a higher percentage of the raw material becomes part of the finished part than in any other process. Plastic injection molding is highly efficient.

What Is Plastic Flow

Mold flow analysis report

What Is Plastic Flow

Plastic flow, in the context of materials science and mechanics, refers to the permanent deformation or reshaping of a material without it undergoing fracture or breaking. This phenomenon occurs in materials that are capable of undergoing plastic deformation, a process where the material can change its shape and retain that new shape even after the applied stress is removed.

The plastic flow of a material is characterized by the movement of dislocations within its crystal structure. Dislocations are defects or irregularities in the arrangement of atoms within a crystal lattice. When an external force is applied to a material, it causes these dislocations to move, allowing the material to undergo plastic deformation.

Unlike elastic deformation, where a material returns to its original shape after the applied stress is removed, plastic deformation results in a permanent change in shape. Plastic flow is a crucial aspect in various manufacturing processes, such as metal forming, where materials like metals and plastics are shaped into desired forms through processes like forging, rolling, extrusion, or molding.

Understanding the plastic flow behavior of materials is essential for designing and engineering products that can withstand various forces and loads without experiencing failure or fracture. Engineers and scientists study the plasticity of materials to ensure the reliable and safe performance of structures and components in different applications.

What Is this process For?

  2. Product Manufacturing:
    • Plastic flow processes are fundamental in the manufacturing of a wide range of products, including automotive components, aerospace parts, household items, and industrial machinery.
  3. Deformation Control:
    • Understanding plastic flow is essential for controlling and predicting the deformation of materials during manufacturing processes. This knowledge helps engineers design components with desired shapes and properties.
  4. Recycling:
    • Plastic flow processes play a role in recycling by allowing the reshaping and reforming of certain materials without degradation of their properties.
  5. Structural Integrity:
    • Plastic flow processes are crucial for ensuring the structural integrity of materials and components. By understanding how materials deform plastically, engineers can design structures that can withstand various loads and stresses.
  6. Cost-Effective Production:
    • Plastic flow processes are often more cost-effective than other methods for shaping materials, making them widely used in large-scale production.
  7. Customization:
    • Plastic flow processes allow for a high degree of customization in product design. Manufacturers can create components with specific shapes and sizes to meet the requirements of different applications.
  8. Efficiency in Mass Production:
    • Plastic flow processes are well-suited for mass production, enabling the efficient and rapid manufacturing of large quantities of products with consistent quality.

Optimizing gates and ram speed profile

Purpose of this example

This example illustrates various aspects of the power of CAE software for the plastics industry, and how such software can be strategically applied. It shows how to put into practice many of the concepts that are discussed in detail in the Design and Processing > Physics topics. These topics include injection pressure, filling pattern, melt-front area and melt-front velocity, runner design and balancing, and gate design.

Description of this example

The example steps through the design considerations for precision molded plastics in a concurrent engineering environment. It illustrates the role of computer simulation at each iterative step in the process. The software package used for this example is C-MOLD Process Solution. Phase I uses C-MOLD Filling EZ to analyze the initial design and determine the gate location and ram speed profile; Phase II uses C-MOLD Filling and Post-Filling for a more detailed analysis of the material selection, part and tool design, and process conditions.

Phase I: Fast and easy simulation with C-MOLD Filling EZ

In this first phase of the design process, we run an initial simulation using C-MOLD Filling EZ, which performs a three-dimensional mold-filling simulation of Newtonian fluids under isothermal conditions. Filling EZ is designed for preliminary analysis of part, gate, and process designs. We then go through several design iterations, each time modifying the design variables (such as location and number of gates), rerunning the analysis, and observing the results. At the end of Phase I, we will have determined the best location for the gate and an optimal ran-speed profile.

  2. Precision and Accuracy: Mold inserts need to be precisely machined to create accurate and consistent molded parts. High-quality materials with excellent dimensional stability contribute to the precision and accuracy of the final product.
  3. Surface Finish: The material used for mold inserts can impact the surface finish of the molded parts. A smooth and high-quality surface finish on the mold insert can translate into a better surface finish on the final product, reducing the need for additional finishing processes.
  4. Wear Resistance: Injection molding involves abrasive forces and high temperatures, leading to wear and tear on mold components over time. Mold inserts made from wear-resistant materials can withstand these conditions, extending the lifespan of the mold.
  5. Heat Dissipation: Efficient heat dissipation is crucial during the injection molding process to prevent issues like warping or uneven cooling. High-quality materials with good thermal conductivity help in managing heat effectively, contributing to consistent part quality.
  6. Corrosion Resistance: Some molding processes involve corrosive materials, and using corrosion-resistant mold inserts helps maintain the integrity of the mold over time.
  7. Cost-Efficiency: While high-quality mold inserts may have a higher upfront cost, they often result in long-term cost savings by reducing maintenance, downtime, and the need for frequent replacements.

It’s essential to note that the specific characteristics and requirements for mold inserts can vary depending on the type of materials being molded, the complexity of the part, and the production volume. Always refer to the manufacturer’s guidelines and industry best practices when selecting materials for mold inserts in your specific application. If “Mold Max” is a specific product or material, it would be advisable to consult the product documentation or contact the manufacturer for detailed information on its properties and benefits.

How to Use Mold Max for Mold Inserts

As of my last knowledge update in January 2022, “Mold Max” was not a specific product or material widely recognized in the field of mold making or injection molding. Therefore, I cannot provide specific instructions on using “Mold Max” for mold inserts without more detailed information.

If “Mold Max” is a proprietary product or a specific material introduced after my last update, I recommend referring to the manufacturer’s documentation or guidelines for precise instructions on usage. Manufacturers typically provide detailed information on the recommended application methods, curing processes, and other essential aspects for their products.

However, I can provide you with general steps for creating mold inserts using common mold-making materials, and you can adapt these steps based on the specific instructions provided for “Mold Max” or any similar product:

  1. Prepare the Master Pattern:
    • Create or obtain the master pattern of the part you want to mold. This pattern is used as a model for creating the mold.
  2. Clean and Seal the Master Pattern:
    • Ensure the master pattern is clean and free of any contaminants.
    • Apply a release agent or sealant to the master pattern to facilitate the demolding process.
  3. Mix the Mold Max Material:
    • Follow the manufacturer’s instructions for mixing the “Mold Max” material. This often involves combining two or more components in specific ratios.
  4. Apply the Mold Material:
    • Brush or pour the mixed mold material over the master pattern. Ensure even coverage and work quickly to prevent premature curing.
  5. Degassing (if required):
    • Some mold-making materials benefit from degassing to remove air bubbles. Follow the manufacturer’s recommendations for this step.
  6. Curing:
    • Allow the mold material to cure according to the specified time and temperature parameters. This may involve leaving the mold at room temperature or placing it in an oven, depending on the material.
  7. Demolding:
    • Once cured, carefully demold the mold from the master pattern. Follow any recommended demolding procedures provided by the manufacturer.
  8. Prepare Mold for Insertion:
    • Clean the mold and ensure it is free from any residues. If necessary, post-cure the mold as per the manufacturer’s guidelines.

Mold Max/beryllium copper which we used in mold inserts for some deep area which cannot be able to add a good cooling channel or not easy to get cooling done. when a part design has deep ribs or many ribs, then MOLDMAX for mold inserts will be better option to solve this issue, this material can get better cooling, but another question is the price, as you know Moldmax is very expensive, it is more expensive than copper, and it is hard to do the manufacturing jobs, it is so hard to do the EDM jobs and polishing jobs.

Another question about this Mold max material for mold inserts is safety to the mold lifetime? I have explained my experience on another post, which I was made 48 cavities plastic molds, all of 48 core inserts made by Beryllium copper, and each insert have around 8 small bosses, it is around 6mm high, after the second mold trial some of the small boss got broken, I remember we have tested the mold around 4-5 times, and every trial got one or two inserts got broken issue, for that mold we made around 8 extra inserts for our customer to prevent this issue, but finally we all know this cost is very high for both customer and us.

Below are some suggestion from some people who provided their experience about Mold max

Shane diet says

Mold Max is not safe at all. I think it gives you a lot more problems. For health, we need to be careful in all ways.

3Pressa says

I have worked with Injection Molding, and can say most plastic is safe as long as you have safety plans, safety equipment in your working space. If science says it is not safe, then it is not safe until they are proof.

4MieleAtlanta says

If science says something is not safe, it means there is proof it isn’t safe. However, as the most interesting man in the world says, ‘safety third’

5JanA says

Too much of anything isn’t safe. So whether beryllium copper is safe or not, which I doubt knowing that copper isn’t safe for the body, I’d rather have myself protected first.

6Zvi says

Yes, you are right in wearing a protective mask while working. Excess of anything is not good and that too for a prolonged period of time, I just can’t be sure. As of for me, I will always prefer taking protection for me whether it is safe or not. We all have just one life, anything in this world is not worth to risk it for.

7Sam says

I’ve heard of a lot of problems so proper protection is a much, better safe than sorry. I plan to research the topic more since I’ve heard mixed things which is a little strange.

15Happili says

You’re right, it’s always better to be safe than sorry. Sure wearing a mask is inconvenient, but the dust definitely cannot be good for you. Who knows what undiscovered side effects could result down the road if you breathe it in too much.

16business entrepreneurship says

Mold Max isn’t safe at all the method of Mold max can be harmful as it creates air pollution as well as water pollution. I am totally against this.

17business entrepreneurship says

Yes, You are right!! it is not safe. Even all Plastic Molding process creates environmental pollution.

How To Make Precision Insert Pins

I am trying to find out how large manufacturing companies grind precision core pins. As a plastic mold maker, I am aware of the manual methods using a surface grinder and Harig type spin fixture and am also familiar with the Ded-Tru machine.

However, these methods are exceedingly slow, albeit quite precise. There just has to be some kind of OD grinder, tool grinder, centerless grinder or special CNC tool grinder that can grind complex mold core pins accurately and with an excellent finish.

Plastic Mold

But in today, normally the mold maker is not making any pins or insert pins by themselves, you can find some precision components company who specializes in making high precision components, like insert pins and some small inserts, you only need to send them the 3D, 2D drawing and mark the tolerance for each dimension, then they will do the rest quickly and accurately.

But for some other mold components, you may have to do this by yourself.

Another common material for various injection mold components is a beryllium copper alloy also called Mold Max. It has excellent heat transfer qualities, can be polished and is also pre-hardened. All this combines to make it the material of choice for things such as core pins.

However, is beryllium copper/Mold Max safe?

In my experience is depending on which area of mold components you are using for? I made 64 cavities molds which the parts have some small ribs, the customer was a requirement with MoldMax for better cooling, as you know sixth four core inserts made by Mold Max, that is not cheap, but after the second time of mold trial the small ribs start to break, not only one or two but around 10 inserts had broken done, base on my experience on this material, for some small ribs it is not good option to use Beryllium copper, if some deep ribs but have much more space, then that will be better option to use this material, because you will get good cooling to save cycle time.

This covers the topic in detail and my conclusion is that it is basically depending on the part design, Is you have a plastic mold project that may need this service, you are welcome to send me your drawing, we will suggest you some good option for you to make choices this could be safer for your project.
