Durable Single Screw Extrusion Machine

Single screw extruder is composed of an archimedes screw rotating in a heated material cylinder ,because of its simple structure ,easy to manufacture ,high processing efficiency ,cheap price and is widely used ,is the most mature technology ,the most amount of extruder type.

Main function of the extrusion system is to melt and plasticize the polymer material to form a uniform melt and realize the transition from a glassy state to a sticky flow state ,and in this process to establish a certain pressure ,is  continuously squeezed  out by  the screw to the nose mold  ,therefore ,the extrusion system  plays an important role in the molding quality and yield of extrusion processing.

Extrusion system mainly includes feeding device ,screw and material cylinder and other parts ,it is the most the screw is the extruder ,in which the screw is the heart of the extruder,the material can be moved in the material cylinder through the rotation of the screw ,and get pressurization and part of the heat.
