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.

Customized Injection Molding Costs

The price of customized injection molding is not standard and depends on how you engage our services and your project specifications. Generally, the cost can be broken down into two main components: the total cost of production and the price of the mold or the tools that are used in the production process.

Tooling Cost/Injection Mold Cost/Rapid Tooling Cost

Making the custom mold entails other costs that are not included in the total cost of production. The custom mold cost is paid at the beginning of the injection molding process and depends on the blueprint design of the mold. The time it takes to create a mold depends on the mold’s design and its intricacy. Plastic parts production is initiated only after the mold has been made or finalized. There are two types of manufacturing processes for mold creation: rapid manufacturing and conventional manufacturing, with different prices and production approaches.

Custom Plastic Molding

high volume plastic injection molding

Custom Plastic Molding

Custom Plastic molding is one of the most cost-effective processes for producing large quantities of plastic products. It uses a die or mold in which melted plastic is injected under pressure, cooled, and hardened to produce the final part before being released. This cycle can be repeated very quickly, possibly 1000 times, which distributes the initial cost of the mold over a large number of units, making the cost per part a few dollars or less.

Repeatability and reliability are achieved because a single mold can be used to produce each part. Furthermore, injection molding provides flexibility in terms of a broad range of material options, colors, finishes, and surface treatments that cannot be matched by CNC machining or 3D printing.

Sincere Tech has a highly skilled workforce with years of experience in different sectors, like medical injection molding and LSR molding. New customers are also given a $500 credit on their first mold with Sincere Tech. We have choices for domestic and custom plastic molding company services from a broader prospect.

Types of Custom Plastic Molding Techniques

In designing custom molded products and their components, it is critical to choose the correct manufacturing process to obtain a high-quality and durable final plastic product with acceptable costs and production time. Here are the most commonly used techniques of custom plastic molding process;

Thermoforming

Thermoforming involves heating a large sheet of plastic to make it pliable and then forming it over a one-sided mold. The use of vacuum pressure or compressed air to force the thermoplastic closely against the mold to the required shape. The advantages of thermoforming are the low cost of tooling, the short time to market, and the ability to produce large parts such as bathtubs and car dashboards. Also, thermoforming is fast in prototyping and can be customized to a great extent.

Extrusion molding

Extrusion molding is mainly applied to produce long and straight products such as tubes, hoses, or pipes. This method involves the use of pressure to force liquid plastic into a specific shape of a die. Although round shapes are typical, t-shapes, l-shapes, and squares are also possible due to the die’s shape. The advantages of extrusion molding are the low cost of tooling and machinery, little or no need for finishing other than cutting the pieces to the required length, and the possibility of attaining intricate and uniform cross-sectional shapes.

Compression molding

Compression molding is most commonly applied with thermosetting plastics, which, when heated and then cooled, undergo a chemical change to become a rigid solid. In this method, the plastic resin is melted and formed into a putty-like substance and then put into a hot mold. The putty is then compacted by the mold and left to cool. Compression molding is suitable for making plastics that compete with metals, are suitable for rigid lightweight thermosets, and are commonly used in fiberglass reinforced or rubberized plastics.

Blow molding

Blow molding is similar to injection molding, where the plastic is first melted and then injected into the mold. Air is then pumped into the plastic, making it expand and conform to the shape of the mold walls. Blow molding is most suitable for manufacturing items that are thin-walled and have a hollow structure, like water bottles or 2-liter bottles for sodas. This method is fast and is relatively cheaper when large quantities are being produced.

Rotational molding

Rotational molding, or “roto-molding,” is the process of placing a mold into a heated container of liquid polymer and then spinning the mold rapidly. This process covers the plastic uniformly on the walls of the heated metal mold while the interior remains empty. Rotational molding is mainly applied to large, hollow-partitioned containers, storage bins, and even kayaks. The advantages of this method include low setup costs, constant thickness of the walls, and low cost for very small or short runs.

Injection molding

Injection molding is one of the best cost-effective molding technology comparing to rest of above, and this is our mean services, we have offering this service over 18 years, if you have any project that need custom injection molding service, welcome to contact us, and you can go to custom injection molding page to know more about this technology.

PEBA (polyether block amide): PEBA is soft and flexible and widely used in the construction of medical instruments such as catheters. PEBA foams are used for padding, shoe insoles, and sports equipment because of their moisture and UV resistance.

PVC (polyvinyl chloride, Shore A): PVC is an elastic thermoset that is a resilient material, and is often used in products for outdoor use, protective coatings, and mats. It needs plasticizers to make it flexible and is famous for its flame resistance.

TPE (thermoplastic elastomer): TPEs are a group of elastomers that possess the characteristics of thermosets but with the processing ability of thermoplastics. They encompass a broad spectrum of special elastomer categories.

LSR (liquid silicone rubber): These are used in foods and biomedical applications due to their heat, biocompatibility, and flexibility. LSR is applied in medical devices, automotive, aerospace, and consumer products, and it is processed differently from injection molding.

Custom Plastic Molding Surface Finishing Options

Standard Finish: This finish, usually SPI B-2, is selected by the mold maker depending on the part’s shape and the angles of the parting line. It is often applied to non-aesthetic parts, and the parts are left machined for functionality without extra expense or time.

SPI Finishes: These are the standard surface finishes set by the Society of the Plastics Industry that dictate the feel and look of the molded parts. They assist in meeting certain aesthetic and functional objectives, which makes them suitable for many uses.

MoldTech Finishes: These are specialized texturing processes that put patterns or textures on the mold surface to improve the aesthetic and feel of the finished part. MoldTech finishes are applied to achieve specific looks and enhanced tactile feel or to mimic other materials such as wood or leather.

Other Textures – VDI: VDI textures are available in various forms, with varying degrees of roughness and appearance to meet certain design requirements. They are widely applied in industries where the surface finish is a critical factor in the product’s functionality or aesthetics.

Design Tips For Custom Plastic Molding

Undercuts: Reduce undercuts to make the tool ejection mechanisms easier and to avoid complications in manufacturing. The use of pass-through coring can also help achieve this goal while at the same time not compromising on the costs of production.

Wall Thickness: Ensure that the thickness of the wall is constant so that there will not be problems such as wall sinks and voids during molding. Reduced wall thickness is beneficial in the aspect of cycle time and cost of manufacturing.

Drafts: Make sure that the parts have a minimum draft angle of 0. 5° to 5° especially when molding textured faces, to ensure that the faces eject smoothly and free from molding defects.

Ribs/Gussets: Make the ribs to be 40-60% of the outer wall thickness while ensuring that the draft angles are correct for the structure. In this case, it is possible to achieve an increase in strength while maintaining the moldability of the gussets.

Bosses: Design bosses with a depth of 30% of the thickness of the wall and include a 30% edge recess for optimal performance.

Benefits & Applications of Custom Plastic Molding

Injection Molded Part: The tooling is inexpensive, and the company can produce parts quickly, with delivery in as little as 10 business days at low prices.

Rapid Prototyping: Injection molding is a fast method of prototyping and can be used to test various designs within a short span.

Production Parts: Custom plastic molds are ideal for manufacturing a large number of production parts at high efficiency and low cost.

Range of Industries and Certifications: Injection molding is used in different fields and complies with the necessary standards to meet the needs of specific applications.
