Injection molding machine is an industrial equipment, mainly used for the production of various plastic products, such as plastic bottles, plastic containers, plastic toys and so on. The injection molding machine produces plastic products of various shapes by injecting the molten plastic into the mold and cooling it into shape.

The working principle of the injection molding machine is to inject the heated plastic material through the mold into the mold and maintain its shape during the cooling process. Injection molding machine is usually composed of the following main parts:

1. Heating system: The heating system of the injection molding machine is mainly used to heat the plastic material and heat it to the required temperature.

2. Injection molding machine control system: The control system of the injection molding machine is responsible for controlling all parts of the injection molding machine, including heating system, injection system, cooling system, etc.

3. Mold system: The mold system of the injection molding machine includes the mold itself and the mold parts, which are used to keep the molten plastic in the mold to form the desired shape of the product.

4. Injection system: The injection system of the injection molding machine is responsible for injecting the heated plastic material into the mold.

5. Cooling system: The cooling system of the injection molding machine is used to cool the injection molding product and maintain the required hardness and strength.

Injection molding machine has the advantages of high precision, high efficiency and high consistency in the production of plastic products, so it is widely used in automotive, electronics, medical, home appliances and other industries. Due to its importance and irreplaceability, injection molding machine has an important position in industrial production.
