Plastic Injection Mold core and cavity inserts are components of a mold used in the manufacturing of plastic and metal parts.
A mold core (sometimes small inserts we call core inserts) is the internal part of the mold, which is normally located at the core side (moveable side). This creates the internal features of the part being molded. The core is typically made out of steel, such as 1.2344, S136, etc., and is typically removable from the mold plate (B plate or pocket plate).
An injection mold cavity insert has the same function as core insert, but is located on the fix side. It is the external part of the mold that creates the external shape of the part being molded. The cavity insert is typically made out of steel, such as NAK 80, S136, 1.2344, and H13, and is typically removable from the mold.
Both the plastic mold core and cavity insert are typically made using the processes of EDM (electrical discharge machining) and CNC (computer numerical control) machining. The core and cavity inserts are then assembled into a mold base to get the complete plastic mold. The plastic injection mold is then used in the injection molding or casting process to produce the desired parts.
Of course there are many manufacturing processes to make plastic mold, such as lathe machining, grinder machining, polishing, wire cutting, milling etc. but CNC and EDM machinings are the most improtant manufacuring process to make an injection molding, belew are briefly explain for EDM and CNC machining:
EDM:
First, a mold design is created in 3D modeling software.
The working piece (cavity and core steel) is then loaded into the EDM machine, which uses electrical discharges to erode the surface of a conductive material (such as steel or aluminum) to create the desired shape of the core or cavity insert.
The finished working piece is then polished or textured according to requirement.
EDM machining process
CNC:
The process is similar, but instead of using electrical discharge machining, a CNC machine uses cutting tools (such as end mills or drills) to remove material from a block of steel or aluminum to create the desired shape of the core or cavity insert.
The finished working piece is then heat-treated to increase its strength and durability, if sue pre-harden steel then no need addtional heat treatment, can move to the EDM machining process directly.
CNC machining process
Both EDM and CNC can produce very precise and accurate parts and are widely used in the manufacturing of injection mold cores and cavity inserts, one important procedure that needs to explain, the working sequence between EDM and CNC, normally CNC machining will start first, then use EDM machining to remove some of area which CNC machining can not do, for example some corners, ribs, bosses, etc.
Guideline for Injection mold cavity and core manufacturing
Some guideline to manufacture mold core and cavity inserts
When we manufacture the injection mold core and cavity inserts during mold manufacturing, there are some dimensions that we need to manufacture with some tolerances so that they fit well in the pocket of the insert plate or mold cavity or core.
And this will save some work when we fit the mold cavity and core. High tolerance and good manufacturing technology will save lots of time for the mold master. Below are some manufacturing mold core and cavity insert guidelines that we need to pay attention to to make high-quality plastic mold.
When we make the corner radius In the manual milling machine, make a 0.2-mm step there; after hardening, we don’t have to grind on the corner when we fit the insert.
For the outside dimension of the plastic injection mold cavity or core inserts, the tolerance should be +/-0.015mm; this will be easy fitting into the pocket, smooth, and of good quality.
The tolerance for the hole in the sprue bushing should be H7 (0/+0.015 mm).
The depth of the treading should be 1.5–2 multiplied by the diameter of the tread. In this case, for the M8 screw, the depth of the treading should be 1.5 to 2 multiplied by 8, equal to 12–16 mm.
The guidance of the ejector pin should be about 15-20 mm long; this will make sure that the ejector pins are ejecting smoothly with a long lifetime.
The clearance area for the ejector pins should be 1 mm bigger than the diameter of the ejector pins. For any question about mold, please contact us.
Making injection mold cavtiy and core inserts are not easy, it must be made by a professional plastic mold manufacturer, if you are running a injection molding shop, and need to make some mold cavity and core inserts to replace the old inserts, or if you have a new mold that want to make all of cavity and cores and assembly this in your injection molding shop, you are welomce to contact us, we can make injection mold cavity and core inserts or completely mold cavtiy and core, moldbase, or completely plastic injection mold for you.
Guidelines to manufacture injection mold core and cavity plates (pocket plates)
As you already knew injection mold manufacturing is not an easy job, if you do not have any good team or experience in this field, I suggest you find a profession plastic mold company to support you, you could do the molding process at your side but make the mold outsource, because make plastic mold need very high technical skill for every worker, compared to injection molding process, mold manufacturing needs more manual jobs than injection molding service, and need high technical requirement as well, below is one of manufacturing guideline for A plate of mold.
When we manufacture the core and cavity plates for a plastic mold, there are some dimensions that we need to manufacture with some tolerances so that our cavity and core insert components or our standard mold components can smoothly assembly in to the plate pocket, and the straight guidance blocks can fit well in the mold base, below are some key points that we need to take care during A plate manufacturing.
When we have straight interlocks at each side of mold base (A and B plates), the tolerance for this dimension should be H7 (0/+0.015mm), that the interlocks can easy to the assembly in the mold base but keep high precision guiding function.
The pocket dimensions for the cavity and core inserts, we should follow the tolerance requirement H7 (0/+0.015mm), so that our cavity/core insert can be smoothly guided into the pocket but have precision dimension.
The location of the hole for the locating pin is important, this is assembly with clamping plate, and the dimension must match to the related hole on the clamping plate, so the tolerance for the locating pins must keep in ±0.01mm, the locating pinholes must have related tolerance H7 (0/+0.015mm), so that the locating pin can easily go in.
If the mold has the hot runner system to work properly, the fitting area needs to have a tolerance of ± 0.01mm, please see below explain.
For the o ring track depth, the tolerance is ± 0.05mm, for the o ring track diameter
The tolerance is ± 0.25mm, this is the same requirement for all of o-ring in the mold.
guideline for cavity and core plates (pocket plates or A and B plate)
Guideline for the clamping plate manufacturing
When we manufacture the mold cavity side of the clamping plate, there are some dimensions that we need to control with some tolerances so that our standard mold components and other parts can fit well in the clamping plate.
For the locating pinholes, the tolerance should be H7 (0/+0.015mm)
The hole diameter for the locating ring, the tolerance should be ±0.02mm
The hole diameter for the Hot runner manifold support insert, the tolerance should be ±0.05mm
The height dimension for the air venting groove on the Hot runner manifold support insert, the tolerance should be ±0.01mm
The slot for the locating pin to the sprue bushing, the tolerance should be 0/+0.10mm
clamping plate manufacturing guideline
The location of the hole for the locating pin is important, this is connecting to another plate, like hot runner manifold plate, or A plate, tight tolerance we make sure that the mold base assembly very well, the tolerance for it should be ±0.01mm.

So what is Design for Manufacturing (manufacturability)? Why do I care? These are a couple questions we hear in the development a new product, before mold manufacturing, this DFM report is an important phase. Design for Manufacturing (DFM) is the process of designing a product in such a way that it is easy and cost-effective to manufacture. This can involve simplifying the design, using standard components, and optimizing the design for the manufacturing process that will be used.
The goal of DFM report is to reduce production costs, improve quality, and increase efficiency. It is an important aspect of the product development process, as it can have a significant impact on the overall success of the product. The basic idea exists in almost all engineering disciplines, but of course the details differ widely depending on the manufacturing technology.
DFM Design for Manufacturing
Why do we need make Design for Manufacturing (DFM) analysis for A new Mold
A Design for Manufacturing (DFM) report analysis is important for a new mold project because it helps to identify potential design and manufacturing issues before the mold is produced, it is similar to the moldflow analysis report for a new mold. This can save time and money, as it is much more cost-effective to make changes to the design before the mold is built, rather than after.
A DFM report analysis includes a detailed examination of the product design and the manufacturing process, and can help to identify issues such as:
Design features that may be difficult or impossible to manufacture
Materials that may not be suitable for the manufacturing process
Assembly processes that are inefficient or unreliable
Potential quality issues that may arise during production
Cost-saving opportunities that can be implemented in the design and manufacturing process.
Part features that may be difficult or impossible to mold
Draft angles that are insufficient for easy part removal from the mold
Wall thicknesses that are non-uniform, which can lead to warping or other quality issues
Undercuts that may require additional mold components, adding cost and complexity to the mold.
Overall, a DFM report analysis can help to ensure that the product design is compatible with the manufacturing process and that the final product will meet the desired quality standards. It also helps to minimize the time and cost of the manufacturing process and can improve the product’s yield rate. Additionally, it helps in identifying cost-saving opportunities and make design improvements that can lead to increase in efficiency, product quality and profitability.
DFM Report Is Intended To Prevent:
I think that is a good overview of the general concept of what DFM (design for manufacturing) is. So the next question is “why is it a problem? There are a number of possible answers for this question.
First possible answer is that the manufacturing technologies are continuously changing so it is difficult to keep up with the new technologies available. This could be true…I am not sold though.
The next answer could be that engineers are not trained properly coming out of college. This is a possible answer but it seems like it blames the problem on someone else.
Last, the answer could be that engineering is no longer performed at the same facility as manufacturing!
With manufacturing moving offshore to locations far away from engineering, the collaboration that existed in the past between design engineering and manufacturing no longer happens. Designs are created and then passed to manufacturing to make parts. Sounds great and very efficient, just not as flawless in practice.
How does an engineer learn about the hidden issue of injection molding? Well, unfortunately, they don’t. Not until they design a part and have it manufactured do they see problems. With that said, there are now services out there to help with the manufacturing process during the product development phase.
We will provide a design for manufacturing (DFM report) for every part before start mold design and mold manufacturing. Go to mold design for injection molding to know more succesfull design for high quality molding. We saw the void created in the industry and want to provide a free service that helps both our customers and us during the mold manufacturing process.
We have seen this as a huge success for customer wanting to proceed to injection molding. This has helped product development companies reduce cost, lead time and ultimately FRUSTRATION.
If you have a new product that plan to make mold and injection molded parts, and you are not sure if your part design is good anough to make high quality molds. Welcome to send us an email to discuss about DFM for your project, we will quote you a price for your project, and will make freee DFM report for you.
If you want to know a completely DFM report, you can download the DFM report sample below.
Two plate injection mold (2 plate injection mold), 3 plate injection mold and all of other type of plastic injection molds are type of molds used in plastic injection molding, in 2 plate mold where two separate mold plates are used to form the mold cavity, one plate we called “A” plate or A pocket plate, which contains the cavity and it is fixing half, and normally we called this cavity side, the other plate is “B” plate (or core side/movable side), which contains core inserts which is moving half, the ejector systmes is also staying at the core side.
The plastic is injected into the mold cavity through the sprue, and then the B plate is closed against the A plate to form the part. Once the plastic has cooled and solidified, the B plate is opened and the part is ejected. This type of mold is generally used for smaller, simpler parts with minimal undercuts or complex geometries.
Advantages of the Two-Plate Mold
two plate injection mold
The beauty of the two-plate design lies in its simplicity. This translates into several advantages:
Cost-effective: With fewer parts and a straightforward design, two-plate molds are the most economical option. It makes the two plate injection mold recommended for high-volume production of parts that are less intricate.
Easy maintenance: Due to their basic design, two-plate molds are easier to maintain and repair.
Fast cycle times: The simple opening and closing mechanism allows for quicker production cycles compared to more complex molds.
Suitable for a variety of materials: They can handle a wide range of thermoplastics, making them versatile for various applications.
Disadvantages of two plate injection moulding
While two-plate molds offer numerous benefits, they also have limitations:
Gate mark aesthetics: The point where the molten plastic enters the cavity (the gate) can leave a visible mark on the final product.
Part complexity: They struggle with parts that have undercuts, deep cores, or threads. These features require additional mechanisms that increase complexity and cost.
Runner waste: The runner system attached to the molded part needs to be removed, generating plastic waste.
The Molding Process in Action
The injection molding two plate mold undergoes a precise cycle to produce plastic parts. Here’s a simplified breakdown:
Clamping: This is when the B-side and the A-side are closed securely together to apply high pressure that guarantees a perfect seal.
Injection: The molten plastic will be injected at high pressure through the designated part or the sprue into the mold cavity.
Packing and Holding: After filling the cavity, pressure will be retained to even out the shrinkage of the plastic while it cools.
Cooling: The mold is cooled with water channels to solidify the plastic part.
Mold Opening: The B-side retracts, creating a parting line where the two mold halves separate.
Ejection: Pins or other mechanisms push the finished plastic part out of the cavity.
Runner Removal: The leftover plastic from the sprue and channels (called the runner) might need to be manually removed from the part.
Difference between two plate and three plate mould
A two plate mold and a three plate mold are different types of molds used in plastic injection molding, with the main difference being the number of plates used to form the mold cavity.
Two plate molds:
Imagine a clamshell. This is the fundamental concept of a 2 plate injection mold. This is made up of two key components. First is the fixed plate or also referred to as the “A-side” and second is the moving plate or the “B-side”.
The magic happens within these two halves. The A-side houses a cavity that replicates the desired shape of the final plastic part. The B-side might have a core that forms internal features or simply acts as a counter to the cavity. These two sides come together to create a sealed enclosure where molten plastic is injected.
have two separate mold plates, the “A” plate and the “B” plate.
The A plate contains the cavity and core, and the B plate contains the ejector mechanism.
The plastic is injected into the mold cavity through the sprue, and then the B plate is closed against the A plate to form the part.
Once the plastic has cooled and solidified, the B plate is opened and the part is ejected.
This type of mold is generally used for smaller, simpler parts with minimal undercuts or complex geometries.
Three plate molds:
have three separate mold plates, the “A” plate, “B” plate and the “C” plate (or runner plate).
The A plate contains the cavity, the B plate contains the core, and the C plate contains the runner the runner pusher with ejector at cavity side (this ejector only ejecting the runner which we call runner pusher as well).
The plastic is injected into the mold cavity through the C plate (runner plate), and then the B plate is closed against the A plate to form the part.
Once the plastic has cooled and solidified, The C plate is opening to pull the runner stick with C plate and then use pusher to ejector the runner off the runner plate, then B plate is opened, and the part is ejected.
This type of mold is generally used for larger, more complex parts with undercuts or other features that cannot be formed with a two plate injection mold.
3 plate mold vs 2 plate mold
In summary, the main difference between two plate and three plate moulds is that two plate mold has the runner which is located on the A or B plate which is on the parting line layer, and ejected out by the ejector systems with part together, the three plate moulds which the runner will stick with C plate ( runner plate), and later one will be ejected by the pusher, and will be more complex and expensive than two plate mold.

How Plastic Injection Molding Contract Manufacturing Works?
The concept of plastic injection molding contract manufacturing is very vital in today’s production industry. This blog contains all the necessary details of this process.
From the drawing board to the manufactured injection molded product, each process counts. Understand the important factors to consider when choosing an Injection Molding Contract Manufacturing company.
How Does Plastic Injection Molding Work?
plastic injection molding contract manufacturing is a delicate process, which means you need to find a expert injection molding supplier to make your products. This molding process is done by pouring melted plastic resin directly into a mold cavity. This is because high-pressure injection guarantees the detailed formation of the part. The mold cools and the shape becomes solid and fixed.
Ejector pins remove the formed part. The cycle time depends on its sophistication level. CNC-machined molds guarantee accuracy. Automated systems streamline production.
Quality control checks help to ensure that standards are kept up. This method is highly effective in mass production of complex components.
What Are the Steps Involved in Plastic Injection Molding Contract Manufacturing?
Design & Prototyping
Plastic injection molding contract manufacturing starts with CAD software. Engineers design precision molds. Every mold should have the exact sizes such as 0.001 mm.
It is possible to produce prototypes using 3D printing. Each cycle enhances deficiencies in design. Simulation tools help to forecast the behavior of injection molding.
Engineers also monitor melt flow rates and cooling times. The choice of material is critical – it can be either a thermoplastic or an elastomer. Design adjustments ensure manufacturability. The prototyping phase leads to minimizing errors in the production phase.
Plastic Injection Mold Making
In the field of plastic injection molding contract manufacturing, plastic mold making comes after prototyping. It is usually made of steel or aluminum. Mold making is done through Computer Numeric Control (CNC) machining. EDM refines intricate details.
Accuracy is very important, and some of parts are made to tight tolerances of 0.05 mm. The cooling channels are incorporated. Ejector pins help in removal of the part.
Polishing helps in improving surface finishes. Cores and cavities which are part of the mold are put together. Mold integrity is checked at the final stage of the process.
Molding Production
Contract manufacturing in injection molding of plastics incorporates high pressure injection. Molding machines use clamping forces which are in tons. The mold is then heated to certain temperatures. This is done by placing the molten plastic into the mold cavity with pressure.
The pressure is kept up until the part has frozen. Mold temperatures are regulated by cooling systems. Operating cycles are smooth and speedy. Part ejection is done by the robotic arms.
This is a way of maintaining the quality of a product or service since the monitoring is done on a constant basis. The volumes of production can be in the thousands of units.
Post-Production
Common finishing steps that are part of post-production in plastic injection molding contract manufacturing are as follows. Casting is then cleaned through trimming and deburring.
Additional operations such as drilling and tapping are carried out. Coatings like painting and plating increase aesthetics. It may be necessary to assemble a number of parts.
Ultrasonic welding is the process of joining plastic parts. Quality checks ensure the accuracy of dimensions. Packaging is important to guarantee that parts are well protected. New production data are incorporated into documentation. The final product is now ready for delivery.
Quality Control
Quality control in plastic injection molding plays a significant role in delivering high quality products. Inspection begins with dimensional analysis. CMM machines measure parts. Visual inspections identify surface imperfections.
Tensile testing verifies the strength of a material. X-ray inspection reveals internal defects. Control charts are used to measure and track production stability. Every batch also goes through some tests.
Non-conforming parts are rejected. Documentation also captures all quality checks. Some the continuous improvement processes that are used include. Quality control helps ensure that the final product remains up to standard.

Behind the Scenes of Plastic Cups with Plastic Cup Mold
If you are someone who ends up throwing the plastic away as the last resort you ought to read this. If it is any consolation to you, you may not be the only person who does this though this could be true at one point.
I find it sad that people do not grasp the massive importance of these plastic cups in this contemporary society. Their contribution can be seen in the very morning coffee takeaway and the crispy iced tea while you spend good time out there.
But do you think how simple containers are produced on a large scale? The answer lies in a hidden champion: Here is the: Mold, pp plastic cup
plastic cup mold
The Molding Process: Alchemy of Plastic
That is why plastic cup molds are the real players that remain unseen. These are highly delicate pieces of metal work that create the shape of molten plastic into forms of items seen and used daily. The two most common techniques commonly used in molding of plastic cups are thermoforming and injection molding.
Thermoforming is more appropriate when it comes to disposable cups. Plastics are heated until they obtain softness and can be easily molded. The mold that is usually made of aluminum then presses it do in order to have the shape of the plastic. Another clay is then applied on it before another vacuum or compressed air is used to knock off excess material to form a perfect Cup form. This process is relatively cheaper and efficient when it comes to the manufacturing of disposable cups perhaps in large quantities.
On the other hand, the use of plastic cup injection mold provides more the requirement of solid and reusable cups. In the process, the material, usually plastic in this case is forced under pressure into a hollow mold. The plastic will then crystallize and contract to the shape of the mold that is on the produced item. This process allows for the thickening of the walls of the plastic and formation of new minute designs. This is wonderful for those cups that should technically last several washes and wears.
The Anatomy of a Plastic Cup Mold
A plastic cup mold is much more than just a hollow form. It’s a complex engineering marvel with several key components:
Cooling Channels
Channels circulating a coolant, which is often water, are embedded within the plastic cup mold. The rapid cooling allows speedy solidification of the plastic to enable faster production cycles.
Core and Cavity
These are the heart of the mold. The core shapes the inside of the cup, while the cavity forms the outside.
Ejection System
Once cooled, the cup needs to be ejected from the mold. Pins or plates push the formed cup out, making way for the next cycle.
Gating System
This intricate network of channels delivers the molten plastic into the cavity. A well-designed gating system ensures proper flow and minimizes waste.
Venting System
As the plastic cools, it traps air. Vents allow this air to escape, preventing imperfections in the final cup.
Beyond the Basics: Innovation in Molds
The world of plastic cup molds is constantly evolving. Here are a few exciting advancements:
In-Mold Labeling
Designs and logos can be directly integrated into the mold, eliminating the need for separate labels.
Multi-cavity Molds
These molds create multiple cups simultaneously, increasing production efficiency.
Stackable Cup Molds
Plastic cup molds produce cups that can be stacked easily together to save space during transport and storage.
How Many Cavities Should a Plastic Cup Mold Have?
The number of cavities in a plastic cup mold will depend on the specific application and the production volume required. In general, the more cavities a mold has, the more cups can be produced in a single cycle. A single cavity mold will produce one cup at a time, while a multi-cavity mold can produce multiple cups at once.
For high volume production, it is common to use a multi-cavity mold with 8, 16, or even 32 cavities. This allows for a high production rate and can help to keep unit costs low. For lower volume production, a single cavity mold may be sufficient.
It is important to note that a multi-cavity mold can be more complex and expensive to produce and maintain. It may also require a higher level of precision and accuracy in the injection molding process.
How to Save on Plastic Cup Unit Price Using a Plastic Cup Mold
There are several ways to save on plastic cup unit price using a plastic cup mold. One way is to choose a more efficient mold design. For example, a hot runner mold can help to reduce plastic waste and lower production costs. Another option is to use a multi-cavity mold, as this can increase production efficiency and lower unit costs.
Another way to save on unit price is to use a multiple cavities of plastic cup mold. This can help to reduce the cost of production. Additionally, it is important to keep the mold well-maintained and to monitor the injection molding process closely to ensure that it is running efficiently and producing high quality cups, check to know plastic crate mould.

The creation of clear plastic injection molding part is a set of complex tasks that are different from those that are faced in injection molding with non-transparent materials. The choice of materials is critical not only to their properties but also to their performance during the production process and in the end product. While working with non-transparent materials, some defects can be hidden to a certain extent, but when it comes to transparent injection molding, the precision of the design and manufacturing processes should be perfect.
However, it is important to note that planning and preparation are very important in the injection molding process before going into the details of the materials used. This entails proper preparation of raw materials, proper calibration of equipment, proper tooling, and proper molding procedures, which are crucial in the production of clear molded parts.
The first criterion that is taken into consideration while practicing clear injection molding is the ability to see the particles. Clear plastics do not mask defects that are likely to be made during molding as compared to opaque plastics. Hence, it is crucial to keep every area of the production cycle as clean as possible to achieve the best quality of the final product. It is important to store the materials properly so that they do not get contaminated and the raw materials are of good quality.
Material Selection For Clear Plastic Injection Molding Process
When it comes to selecting materials for translucent and clear injection molding, several options offer distinct advantages:
Acrylic (PMMA): Acrylic is a versatile material that can be used to injection mold clear as well as colored products. It is well known for its nontoxicity, scratch resistance, and UV resistance and is widely used in outdoor equipment, lighting fixtures, and decorative items. However, the rigidity of acrylic and its brittle nature requires proper drying to avoid moisture which affects the molding process and the final product. Go to Acrylic injection molding page to know more about PMMA molding.
High-density Polyethylene (HDPE): It is UV resistant and can be molded into translucent parts which is an advantage of HDPE. It is more resistant to breakage than acrylic and is relatively cheaper hence suitable for use in containers, bottles, and pipes among others. Nevertheless, HDPE is not recommended for high-pressure applications because of its relatively low impact strength.
Polycarbonate (PC): Polycarbonate is clear, resistant to UV light, and is more resistant to impact than acrylic. It is widely used in safety clothing, windows, containers, and other applications that require high-impact strength and transparency. Like in the case of acrylic, PC also needs to be dried before injection molding to get the best performance. learn more about Polycarbonate injection molding.
Polyetherimide (PEI): PEI is a high-performance material that exhibits excellent resistance to UV, heat, and chemical environments. It is widely used in high-performance applications like medical instruments, automotive parts, and aerospace components where high mechanical performance and thermal characteristics are desirable. However, due to its high cost and the requirement of specialized manufacturing processes such as the use of steel molds, PEI is most appropriate for applications that require high performance.
Polypropylene (PP): PP is a very useful material that is characterized by flexibility, electrical conductivity, and chemical stability. It is used in numerous industries for uses like fabrics, packaging, electronics, and chemical uses. Due to the hinge-like characteristic, PP is best suited for applications where flexibility and resilience are required and the part is not expected to bear any load.
Liquid Silicone Rubber (LSR): LSR is a biocompatible material with good thermal, chemical, and electrical stability. It is widely applied in medical equipment, electrical parts, and automobile manufacturing industries where strength and efficiency are vital. Due to its flexibility and enhanced characteristics, LSR is well suited for applications where high accuracy in molding and high performance are required.
Optical Silicone Rubber (OLSR): OLSR is an advanced material that is used for improving the light transmission and clarity of optical parts. It has better non-yielding characteristics and hence can be used in outdoor fixtures and other applications where the product is exposed to extreme weather conditions. Due to its good stability of optical transmittance over time, OLSR is suitable for clear optical parts where light transmission is important.
All these materials have their own benefits and challenges when it comes to clear injection molding, and they are suitable for use in different applications across various industries. The choice of materials, design, and manufacturing techniques are well thought out and implemented to produce clear molded parts that are of high quality, performance, and appearance.
Polyethylene (PE)
HDPE is made through a process in which petroleum is exposed to heat and pressure and is a type of thermoplastic. While acrylic has its advantages, HDPE has UV resistance, is incredibly versatile, and is easy to mold. Because of these advantages and the fact that it is relatively cheaper to manufacture, HDPE is commonly used in large-scale production of products such as bottles, pipes, and containers.
Elastomeric Resins
TPR is one of the elastomeric resins which are a combination of plastic and rubber that can be easily processed through injection molding. TPR has uses in products such as fluid dispensers, flexible hoses, catheters, and equipment that need to have resistance to liquids such as acids. For these applications, it is preferred due to its flexibility and ability to withstand tough conditions.
Thermoplastic Polyurethane (TPU)
Thermoplastic Polyurethane (TPU) is characterized by high tensile and tear strength, softness, and elasticity. This makes TPU suitable for use in the development of products that need to have a firm handle while at the same time being comfortable to hold. Even though TPU is comparatively costlier than the other resins, it is widely used for creating parts with rubber-like attributes.
Some of the common defects that are evident in clear plastic parts and the possible solutions include the following:
Plastic parts that are transparent are vulnerable to different kinds of defects during the molding process. It is important to know these defects and how to avoid them in order to manufacture high-quality transparent products. Here are some of the most common defects and their respective solutions:
1. Air Traps
When molding the resin, it is not uncommon for air pockets to be locked into the material, which will be evident in the final product. This is usually a result of poor venting or low pressure during injection of the material.
Solution: The air traps can be reduced and the product transparency increased by enhancing the mold design to incorporate the correct channels for venting and by increasing the injection pressure.
2. Flow Lines
Flow lines are those lines or streaks on the surface of the clear plastic parts that are formed due to the difference in the flow of the material during the injection molding process. These lines can mar the beauty of the product.
Solution: Changing the injection speed and pressure and also the gate design can be used to minimize flow lines and enhance the general surface finish of the part.
3. Sink Marks
Sink marks are small indentations on the surface of the plastic part, which are usually formed due to differences in the cooling rate or improper filling of the resin during the solidification process.
Solution: Reducing cooling time, controlling packing pressure, and applying proper mold temperature control measures can go a long way in reducing sink marks and enhancing the quality of the part.
4. Surface Scratches
Some of the surface defects that may be observed include scratches or marks that may be caused by handling or ejection of the molded parts and this will affect the degree of transparency and surface finish of the parts.
Solution: Proper handling and ejection procedures, mold release agents, or surface treatments can help avoid surface scratches and ensure product clarity.
5. Hazing or Cloudiness
Misting or clouding of clear plastic components can be caused by several factors, such as inadequate drying of the raw material, contamination, or high moisture content during the molding process.
Solution: To avoid hazing and obtain clear, transparent parts, it is necessary to pay attention to the correct handling and storage of materials, the use of dry resins, and the correct processing conditions.
If these defects are corrected and the right solution is applied, manufacturers can create clear plastic parts with good clarity and aesthetic value.
Surface Finishing Selection and Design Tips For Clear Injection Molds
In as much as the clarity of the plastic parts is concerned, choosing the right surface finish is very important. Manual sanding and polishing are useful for rougher designs that do not have fine details, but they are not efficient for creating clear products. If the production run is low or if the prototype or project is a one-off or off, then the SPI-A2 finish may be adequate, especially if surface finish is not a consideration when evaluating a prototype. It was also seen that if the concept of surface finish is deferred to the production level, then a lot of time and money could be saved.
For flat or nearly flat transparent parts such as windows or lenses, the best surface finish is the resin coating. However, it is crucial to understand that the use of a release agent is disadvantageous to the part’s surface and should not be used. It is important to note that lead times and costs of surface finishing may differ depending on the project.
As for the recommendations for the design of the clear or translucent parts, several aspects should be taken into account. It is also important to keep the wall thicknesses constant throughout the part to keep the clarity consistent. Other considerations include designing gate runners that are wide enough and placing gates in such a way that they will accommodate the contraction process. The lack of sharp corners, especially for PC products, helps to avoid gaps and make the transitions clearer.
Furthermore, maintaining a smooth surface of the mold and proper cooling will reduce the surface defects and the decline in the clarity of the plastic in clear plastic injection molding. To get more specific design recommendations for transparent injection molding, it is suggested to read more about it.
