Plastic products are made of a mixture of synthetic resin and various additives as raw materials, using injection, extrusion, pressing, pouring and other methods. While plastic products are being molded, they also obtain the final performance, so plastic molding is the key process of production.
1. Injection molding is also called injection molding. It is a method of using an injection machine to quickly inject molten plastic into a mold and solidify it to obtain various plastic products.
2. The extrusion molding method is a process that uses screw rotation and pressure to continuously extrude the plasticized plastic into the mold, and when passing through a certain shape of the die, a plastic profile suitable for the shape of the die is obtained.
3. Compression molding, also known as compression molding, compression molding, compression molding, etc., is to add solid pellets or prefabricated pieces into the mold, and use heating and pressure to soften and melt them, and under pressure The method of filling the mold cavity to obtain plastic parts after curing.
4. Blow molding (belonging to the secondary processing of plastics) is a processing method in which hollow plastic parisons are blown and deformed by means of compressed air, and the plastic parts are obtained after cooling and shaping.
5. The casting of plastic is similar to the casting of metal. That is, the polymer material or monomer material in the flowing state is injected into a specific mold, and under certain conditions, it is reacted, solidified, and formed into a processing method of plastic parts consistent with the mold cavity.
6.Gas-assisted injection molding (referred to as gas-assisted molding) is a new method in the field of plastic processing. Divided into hollow forming, short shot, and full shot.
