The choice of plastic parts mainly depends on the type of plastic (thermoplastic or thermosetting), the starting shape and the shape and size of the product. The production of injection molded parts are generally molded, transfer molded, but also injection molding. Lamination, moulding, and thermoforming are molded on the surface of the plastic. All of these methods can be used for rubber processing. In addition, there are liquid monomer or polymer as the raw material of the casting.
In these methods, extrusion and injection molding are most commonly used, and are the most basic molding methods.
