What Are Plastic Dies?

Before learning how to make plastic parts, it is necessary to understand plastic dies. Plastic dies are special tools that give shape to plastic parts. They are usually made of tool steel, a robust and durable metal. Tool steel has many types, but the H13 tool steel is the most common for making plastic dies.

Making plastic dies also needs careful attention. First, engineers design the actual part. Then, they create a prototype of the part. Later, based on the shape of the part, they make the plastic dies. Then, various surface treatments are employed to achieve the highest accuracy. Sincere Tech, in this case, gives a tolerance of up to ±0.01mm. Finally, the plastic dies are tested and moved for the final production.

How to Make Custom Plastic Parts?

Custom-molded plastic parts can be made in various ways, each with a unique purpose. This diversity generally arises from the many forms of plastic products.

Some are hollow, while some are solid. Also, some are profile-shaped, while some are rigid small parts. Therefore, the right way depends on the plastic parts and their design. It typically considers the size, shape, and purpose of the part.

Method #1: Custom Injection Molding

Custom injection molding is the most common plastic parts manufacturing process. The process injects the molten plastic into the dies. When cooled, it gives various plastic shapes. Because of this, the process is termed the plastic injection molding process.

How do you distinguish whether the part is made from injection molding or other types? It is simple. When you hold plastic parts, if you see a parting line, the plastic part is made from injection molding.

Going in-depth, you will find injection molding of three major types. (1) Hydraulic injection molding inserts the molten plastic by hydraulic forces. (2) Electric injection molding inserts the molten plastic by electrically produced forces. (3) Hybrid injection molding uses both technologies.

How Does Custom Plastic Injection Molding Work?

Custom injection molding starts by choosing the suitable material. This method uses many plastic grades, including PC, ABS, PP, PVC, LDPE, and HDPE. The right type typically depends on the application requirements. For example, polycarbonate can work at high temperatures, while ABS is easy to process.

The raw materials are often supplied in pallet form. A pallet is a small and uniform piece. An operator first puts these pallets into the hopper. Then, the hopper automatically passes them to the heating chamber. This chamber melts the pallets and pushes them into the dies using screws. This pushing requires a lot of pressure to ensure the liquid plastic reaches every part of the die.

Once the mold is filled, the cooling phase begins. There are several types of cooling, either air or water cooling. Finally, the operator presses the ejection pin and removes the custom injection molding part from the die. In this way, plastic factories make hundreds and thousands of custom-molded plastic products.

Advantages of Custom Injection Molding

The high pressure typically guarantees accurate results.
Custom injection molding is the best method for making complex plastic parts.
You can typically work with any plastic. But you must be careful with the defects when cooling. Some plastics show shrinkage during solidifying.
The die always ensures the consistent quality of the product.
It produces almost no waste.

Limitations of Custom Plastic Injection Molding

Custom injection molding is suitable for small—to medium-sized components. Larger sizes require larger dies, which can be expensive.
Tooling cost is relatively higher.

Method #2: Blow Molding

You can also create custom-molded plastic products by blow molding. As the name suggests, this method blows molten metal into a mold to make it hollow. You can make bottles, tanks, and big containers this way. Because of this, people call this process blow molding.

There are several types of blow molding: extrusion, injection, and stretch blow molding. Blow molding creates all kinds of hollow containers.

Benefits of Blow Custom Plastic Molding

This method is ideal for creating hollow parts. The produced custom-molded products are also light.
Blow molding is a cost-effective solution for high-volume orders.
It also needs less upkeep costs.

Limitations of Blow Custom Plastic Molding

This method can only produce hollow parts.
Blow molding is only suitable for simple designs.

Method #3: Rotational Molding

Rotational molding is also used to create hollow custom-molded products. Interestingly, people also call it roto-molding. In the factory, first, an operator places the powder plastic in the mold. Then, he continuously rotates and heats the mold. This step is mainly automated. For smaller parts, some workshops may do manual rotation.

Because of heat, the powder plastic melts down. On the other hand, the rotation allows it to reach all the surfaces. The combination of these two factors maintains a uniform distribution of molten plastic.

Benefits of Rotational Molding

Ideal for more oversized custom-molded products.
Roto molding is ideal for low-volume orders.
This method doesn’t produce any waste.

Limitations of Rotational Molding

Roto molding is not suitable for smaller hollow plastic parts.
This method is less accurate.

Method #4: Compression Molding

Compression molding is also widely used in custom-molded product making. In this method, first, an operator places the pre-heated plastics inside the mold. Then, he closes the other half of the mold. At this stage, the machine heats and compresses the plastic. The plastic gradually melts and forms the desired shape.

After cooling, the operator gently removes the part. This method is ideal for creating many car, aircraft, and machine parts.

Benefits of Compression Molding

Compression Molding needs low tooling costs.
It is suitable for high-strength products.
This method creates long-lasting custom-molded products.
Compression molding also produces less waste.

Limitations of Compression Molding

This method is not suitable for high-volume orders.
It can not produce complex plastic parts.

Introducing Custom Molded Rubber Products

Custom-molded rubber products are unique rubber parts. In general, you won’t find them in the market. They are essential in many fields. People prefer custom-made products to fit unique specifications. You will need them when standard rubber products don’t meet your needs.

The car industry needs special gaskets, seals, and vibration dampening. Planes also depend on rubber to handle high temperatures and pressures. Custom rubber parts are prevalent in many sealing applications. Besides, the toy industry also needs rubber. Therefore, you can realize how huge this market is. You have many opportunities to start your business in it.

Custom-molded products have many benefits, but custom rubber parts have some limitations. The main limitation is the tooling cost. Every rubber product shape has a unique die, and creating dies requires time, effort, and money. Besides, working with complex design might be challenging as well.

How to Choose the Right Rubber for Your Project?

Rubber comes in many types and grades. Some typical names are natural rubber, NBR, and neoprene. Each has its unique benefits. Natural rubber is excellent for elasticity. It is cheap and easy to get.

On the other hand, NBR and neoprene work great against chemicals and oils. EPDM is suitable for weather resistance. And silicone can resist high heat.

When picking a suitable rubber material, consider a few things. First, consider the environment where you will use your custom rubber products. Does it involve UV rays, extreme weather, or high temperatures? Then, check the rubber’s features. Third, how often will your rubber item be used? Lastly, look at the prices and see how they fit with what you need for the project.

How to Make Custom Molded Rubber Parts

You can typically create custom-molded rubber parts in various ways. Each method offers a unique way to shape your rubber parts.

Method #1 Rubber Injection Molding

Rubber injection molding is a comparatively fast way to create various custom-molded products. First, an operator inserts the rubber pallets into the hopper. Then, the hopper automatically transfers it to the heating chamber. Inside the heating chamber, the rubber pallets gradually melt into liquid rubber.

Then, the injection chamber pushes this molten rubber into the dies. The pressure must be sufficient to reach every corner of the mold. Once cooled, the custom-molded products are removed. Finally, the operator performs some additional finishing, like cutting extra parts.

Rubber injection molding is ideal for creating complex rubber parts. However, this method can not make hollow tubes or containers. For hollow parts, you can use extrusion methods.

Method #2 Rubber Compression Molding

Rubber compression molding is a more straightforward process. In this method, an operator first places the pre-heated rubber compound inside a mold. Then, he closes the mold. When he starts the machine, it automatically heats the compound and compresses towards the edges. In this way, the hot rubber compound gets the final shape.

Compression molding is typically suitable for making bigger-size parts. However, it is not the best method for making complicated parts. Rubber mats, grommets, and big seals are all common examples. This method is a cost-effective solution.

Method #3 Rubber Transfer Molding

This method, also known as the hybrid method, combines injection and compression molding. To understand the process clearly, you must know what transfer molding looks like.

Typically, a mold consists of two halves: one remains still, and the other moves. In transfer molding, one half contains a chamber called the “pot. ” If you look closely, you will find small sprues from the “pot” to the mold.

Now, an operator puts a pre-heated rubber compound in the “pot. ” Then a plunger pushes it. The molten rubber travels through sprues and reaches every corner of the mold. So, you can see that both compression and injection methods have been used. Because of this, the technique is called hybrid molding.

The best thing about this method is that you can fill multiple molds simultaneously. When a plunger pushes the rubber compound, it fills all the molds equally. As a result, you can create more custom rubber parts. Therefore, this method is suitable for large-volume orders. Rubber sandals, toys, and seals are made through this method. Since it can produce more products at a time, it reduces manufacturing costs, too.

Frequently Asked Questions

How much does a custom injection mold cost?

A custom injection mold may cost, on average, $1,000 to $5,000. The price typically depends on the complexity, size, and material. Simple molds for small parts are generally less expensive. On the other hand, the oversized mold may cost up to $80,000. The material used in the mold may also affect the total price.

How Profitable Is Injection Molding?

Injection molding can be highly profitable, especially for large quantity orders. Typically, this process takes 2 seconds to 2 minutes to complete one cycle. The time depends on the size and density of the final part. If you take an average of 1 minute for each product, you can complete 60 cycles per hour. Therefore, injection molding can be a profitable business.

What is the strongest plastic mold?

Polycarbonate, or PC, is famous for its high-impact resistance and longevity. It can be used to make the most rigid plastic mold.

Polycarbonate can withstand heavy loads, high heat, and a few chemicals. Because of these properties, PCs are prevalent in making many valuable items. For example, safety helmets, eyewear lenses, and car components are noteworthy.

What is the difference between plastic and rubber injection molding?

The main difference lies in using pressure and temperature during injection molding. Rubber injection molding applies more heat and pressure to the mold cavity. On the other hand, plastic injection molding typically uses less pressure. During cooling, rubber needs constant pressure, while plastic doesn’t.

Why is injection molding better than compression molding?

Custom Injection Molding: An Overview

Custom injection molding or injection molding mold parts is a plastic part fabrication process that involves injecting stringent quality material into a mold die or cavity designed specifically for intended applications. This process allows design manufacturers to produce parts in low volumes to bulk. Generally, it’s also known as injection molding of plastics, as this process is carried out in the following manner.

The process starts by forcing molten polymer into a mold designed to match the shape of the desired product. The polymer is then cooled and solidified to form the required part released from the mold. The custom injection-molded parts or products manufacturing process provides flexibility and can be used for medium production for about a few 100s to manufacture 1000s of identical molded components at a large scale. The process is widely favored for its economic production and helps industries like automotive, aerospace, and electronics to fabricate prototypes for functional testing and enhance the aesthetics of intended products or end-use parts.

Custom Plastic Injection Molding Materials

The types of plastics used in custom injection molding are diverse, with different melting points and peculiar characteristics that can be adjusted to suit a specific application. Here are some commonly employed thermoplastic materials for manufacturing high-quality injection molded parts.

Acrylonitrile Butadiene Styrene (ABS)

ABS is a widely used thermoplastic material that offers flexibility, low density, and good impact strength. It is unsuitable for applications requiring chemical, electrical, or UV resistance. Because of its strength,

ABS injection molding is widely used in products such as children’s toys, household appliances, and car parts.

Low Density Polyethylene (LDPE) & High Density Polyethylene (HDPE)

These versatile thermoplastics provide high tensile and impact strength and resistance to moisture. HDPE injection molding is used in consumer and industrial products, while LDPE, which is softer, is also used in similar applications. Both materials are appreciated for their high degree of durability and ability to be bent.

Polypropylene (PP)

PP injection molding part is a tough plastic with good chemical and stress resistance and high impact strength. Due to its high melting point, it is ideal for use in the food industry, where equipment must be durable and safe for use with food products.

These materials are chosen according to the application’s needs to provide the best performance and long life of custom injection-molded parts.

Tool Design and Engineering

In injection molding, the tool is the mold or die that forms the material into the intended part. It’s in fact a negative cavity that recreates the part’s shape with the correct dimensions to allow for the material to behave as desired during injection and cooling. In the production of custom molded plastic parts, it may be necessary to use one or several tools depending on the need. Although using more tools initially raises the cost a little, it greatly reduces the cost per piece in the long run, making it economical for mass production.

These tools are located in a mold base and are a single component of injection molding machines. Mold bases are costly, so we use insert tooling that can be fitted into existing polymer molding mold bases.
