Plastic injection molding machine It is a common equipment, which is used to heat and melt the plastic raw materials and inject them into the mold to form the required plastic products. It is widely used in various industries, from auto parts to household products, from electronic product shells to packaging containers, all can be manufactured through plastic injection molding machines. How does the plastic injection molding machine work? You may not know it very well. Next, we will follow Liansheng Precision injection molding machine Let's have a look.

The injection process of plastic injection molding machine can be roughly divided into the following steps:

1. Plastic feeding: first, load the required plastic raw materials into the hopper of the injection molding machine. These raw materials can be granular, powdery or a mixture between particles.

2. Heating and melting: the injection molding machine heats the plastic raw materials to a specific temperature through a heater to melt them into a flowing state. The heater usually adopts electric heating, hot oil circulation or steam heating.

3. Injection: Once the plastic melts, the injection system of the injection molding machine injects the molten plastic into the mold. The injection system is composed of injection cylinder and screw. The screw rotates to push the molten plastic forward, and the injection cylinder applies pressure to inject the plastic into the mold cavity.

4. Cooling: Once the plastic is filled into the mold, the cooling system starts to work. The cooling system cools the mold through the circulating cooling medium (usually water), so that the plastic can rapidly solidify and solidify in the mold.

5. Mold opening and demoulding: When the plastic is completely solidified, the injection molding machine will open the mold and take the molded plastic products out of the mold. This step is usually completed with the help of an ejector or a manipulator.

6. Cycle repetition: after completing one injection cycle, the injection molding machine can start the next injection process and cycle production.

It is about the "introduction to the knowledge of how plastic injection molding machines work". Do you know it after reading it? I hope it will be helpful to you.
