With the improvement of people’s living standards, the requirements for the quality of life are also getting higher and higher. As an important industrial material, plastics are widely used in all walks of life.

The principle of plastic molding

Plastic molding is a type of process that manufactures moldings by processing plastic materials. It is an important link in plastic processing and a key process in the production of plastic products. Plastic molding includes various processing methods of plastics, such as injection molding, extrusion molding, compression molding, thermoforming, etc. The plastic molding process is an important link in the production of plastic products, and it plays a key role in determining the quality of plastic products. Plastic molding has many advantages, such as: 1. Low cost: Plastic molding is a relatively low-cost process, usually only about half the cost of metal molding. 2. Good product quality: The quality of plastic molded products is generally better than that of metal molded products. 3. Simple process: The process of plastic molding is simpler than that of metal molding, generally does not require special equipment and process conditions, and is easy to achieve mass production.

Methods of plastic molding

Plastic molding methods mainly include injection molding, extrusion molding, blow molding and shell molding. Injection molding is a method of injecting plastic raw materials into a mold in the form of liquid, and then heating and drying to solidify it. Extrusion molding is a method of extruding plastic raw materials in solid form. Blow molding is a method of blow molding plastic raw materials in the form of gas. Shell molding is a method of forming a shell from a plastic raw material.
