The sheet extruder is the main machine of the extrusion production line. Its function is to plasticize, transport raw materials and provide the pressure required by products. Extrusion molding has the following advantages: the processing process is continuous, the production and manufacturing is efficient, the application coverage is wide, and it can produce and manufacture pipe fittings, bars, plates, cables, PVC profiles, etc; Small investment, quick gain. Sheet extruder, as the key equipment for the production and processing of polymers, has become a series of universal and standardized mechanical equipment commodities in many countries and mechanical engineering in China. There are many types, their application scope, and performance parameters are expressed by relevant main parameters.
Sheet extruders are classified as follows:
According to the number of screws, it can be divided into single screw extruder and twin screw extruder; It can be divided into exhaust extruder and non exhaust extruder according to whether exhaust or not; According to the position of the screw, there are two types of extruders, i.e. the rotary extruder and the horizontal extruder.
Sheet extruder is generally composed of extruder, die head, die mouth, auxiliary machine, etc. The extruder has basic equipment (screw and barrel). Transmission device and heating and cooling.
