Manufacturing plastic products requires the use of injection molding machines. These come in a variety of sizes and types, each of which is designed for specific applications.
In this article, we will take a look at some of the more popular types of injection mold machines and what they’re used for.
Injection molding machines are classified by the type of driving system they use. There are four main types of injection molding machines, all of which vary slightly in terms of cost, speed, and size.
What Kind of Products are Made Through Injection Molding?
Injection molding is a manufacturing process for creating parts by injecting molten material into a mold. Injection molding can be used to create a wide variety of parts and products, including:
- Plastic bottles
- Medical syringes
- Toys
- Brush bristles
- CD cases
- Dishwasher parts
- Automotive parts
The vast majority of plastic products that you come into contact with on a daily basis are made through injection molding. Injection molding is an extremely versatile manufacturing process, capable of creating parts and products from a wide variety of materials.
Hydraulic Injection Mold
The first type of injection molding machine is the hydraulic injection molding machine. This machine uses a pump to force the molten plastic into the mold at high pressure. The advantage of this machine is that it is very fast, making it ideal for high-volume applications.
The downside of this machine is that it is more expensive than other types of injection molding machines and can be less precise.
Electric Injection Molding Machine
The second type of injection molding machine is the electric injection molding machine. This machine uses electricity to heat the plastic, which is then injected into the mold. The advantage of this machine is that it is more precise than the hydraulic injection molding machine.
It is slower than the hydraulic injection molding machine and can be more expensive.
Toggle Injection Molding Machine
The third type of injection molding machine is the toggle injection molding machine. This machine uses a toggle to inject the plastic into the mold. The advantage of this machine is that it is more precise than the hydraulic and electric injection molding machines.
Two-Stage Injection Molding Machine
The fourth type of injection molding machine is the two-stage injection molding machine. This machine has two cylinders, one for the plastic and one for the mold. The advantage of this machine is that it is more precise than the hydraulic and electric injection molding machines.
Rotary Injection Molding Machine
The fifth type of injection molding machine is the rotary injection molding machine. This machine uses a rotating screw to inject the plastic into the mold. The advantage of this machine is that it is very fast, making it ideal for high-volume applications.
Pneumatic Injection Molding Machine
This machine uses compressed air to push the molten plastic into the mold. The advantage of this machine is that it is very fast, making it ideal for high-volume applications.
Are Any of These Machines Better for Specific Parts?
Electric injection molding machines are typically better for smaller and more precise parts. Hydraulic injection molding machines are usually better for larger parts.
Rotary injection molding machines are better for high-volume applications. Pneumatic injection molding machines are also better for high-volume applications.
For the most part, it is up to the manufacturer to decide which type of machine is best for their specific application. In some cases, multiple types of machines may be used in order to produce a single product.
Different manufacturers will have different preferences when it comes to the type of machine they use. Some manufacturers may prefer one type of machine over another, while others may use a combination of machines in order to get the best results.
The best way to determine which type of machine is best for your application is to consult with an expert. They will be able to help you determine which type of machine is best suited for your needs.
Best Machine
Injection molding machines are classified by the type of driving system they use. All provide advantages, so the best machine is the one that best fits your specific application.
Overall, injection molding is a highly versatile manufacturing process that can be used to produce a wide variety of parts and products.
In order to determine which type of machine is best for your specific application, consult with an expert. They will be able to help you determine which type of machine is best suited for your needs.
