In extrusion molding, the extruder, die and die, as well as the corresponding auxiliary devices are generally selected according to the type and shape of the processed products, and then the extrusion process conditions are determined, such as screw speed, die pressure, setting temperature, etc. In the process of extrusion, the material is usually plasticized, cooled and cured or vulcanized. Different products can be obtained by different extrusion processes.
