一般根据所加工聚合物的类型和制品或半成品的形状，选定挤出机、机头和口模，以及定型和牵引等相应的辅助装置，然后确定挤出工艺条件如螺杆转速、机头压力、物料温度，以及定型温度、牵引速度等。在挤出过程中，物料一般都要经过塑炼，但定型方法则有所不同。例如，挤出的塑料常需冷却定型，使其固化，而挤出橡胶的半成品，则尚需进一步硫化。采用不同的挤出设备和工艺，可得到不同的制品。
Generally, according to the type of polymer processed and the shape of products or semi-finished products, the extruder, head and die, as well as the corresponding auxiliary devices such as setting and traction are selected, and then the extrusion process conditions such as screw speed, head pressure, material temperature, setting temperature and traction speed are determined. In the process of extrusion, the materials generally have to be plasticized, but the setting method is different. For example, extruded plastics often need to be cooled and shaped to cure, while semi-finished products of extruded rubber need to be further vulcanized. Different products can be obtained by using different extrusion equipment and processes.
