Mar 10, 2018

The structure of a single screw extruder is made up of several parts, such as the extrusion system, the transmission system, the heating and cooling system and the control system. In addition, there are some auxiliary equipment for each extruder. The extrusion system is mainly composed of feeding device, barrel, screw, head and die and so on. It is the key part of extruder forming. Its role is to enable the melt into a homogeneous melt, and quantitative, constant pressure extrusion, extrusion molding plays an important role in the quality and quantity of the transmission system mainly consists of motor, speed control device and transmission device, its role is to provide the torque and speed needed to screw 6. Heating and cooling system by heating and cooling device, its role is to ensure the extrusion process in the process requirements of the temperature control system is composed of a variety of electrical appliances, instruments and related executive mechanism, its main role is to ensure that the extrusion process in process conditions.
