In order to become a successful plastic injection molding manufacturer, it is essential that you have the necessary knowledge and skills in order to handle all aspects of plastic manufacturing. Let’s look at the process and see how plastic injection molding works;

 

Plastic Injection Molding Process

Injecting plastic into a mold is commonly done through the use of an ejector and a palate. The plastic then flows into the desired shape through the two parts.

 

The process of injection molding consists of four phases. These stages are injection, cooling, clamping, and ejection.

 

Due to its mass production function, injection molding is commonly used in the plastic industry. It creates complex components at high speed and pressure.

 

Injection Molding Machines

Various components such as the feed zone, the nozzle, the heating unit, the injection chamber, and the platen are used to make injection molded parts.

 

How Injection Molding Works, Step by Step Procedure

Before plastic items are molded, they should be designed and inspected to ensure their quality. The companies then decide on the type of plastic that they will use for their products.

 

1. Setting of Mold

The parts are arranged in a robotically or hand-operated manner. The mold’s two halves are then shut down carefully by the machine's hydraulic press.

 

2. Extrusion of Plastic

The plastic pellets are then expelled through a hot chamber. The process is done with a screw tool to make the extrusion process easier.

 

3. Molding Process

Molds are made using plastic that has been melted. The plastic is then injected into the molds according to the manufacturer's specifications. The entire process of injection molding is complex. It involves carefully performing the steps and keeping an eye on the pressure of the mold. Only experienced individuals can handle the injection machine effectively.

 

4. Cooling & Releasing of Parts

The plastic parts are kept cool in the molds until they become solid. After the cooling period is over, the plastic parts are allowed to open. Injecting plastic parts into a mold depends on their properties. The parts are then ejected through a mechanical or compressed air method. The force is then used to take the parts out of the mold.

 

5. Post Processing

The runners are the parts that are used to fill the cavity of a mold. They are easily removed from the parts by removing the plastic substrate.The process of injection molding is very fast and accurate. It produces high volume parts with a low lead time. The skilled team members and laborers of injection molders make sure that the finished products are of high-quality. This process increases the reliability of the finished article.
