216. Plastic molding
Plastic molding is a variety of forms (powder, granules, solution and dispersion) of the desired shape of the products made of plastic or blank process. Up to thirty several molding method.
Plastic molding is mainly determined by the choice of the type of plastic (thermoplastic or thermoset), initial shape and the shape and size of products. Thermoplastic processing methods commonly used in extrusion, injection molding, calendaring, blow molding and thermoforming, etc., processing thermosetting plastics commonly used molding, transfer molding, injection molding is also used.

Laminating, molding and thermoforming is the molding of plastic in the plane. The plastic processing method can be used for rubber processing. In addition, a liquid monomer or polymer as raw material, casting and so on. In these methods, the extrusion and injection molding with the most, is the most basic molding methods.
