Single screw extruder is one of the important molding methods for plastic molding processing. The material is formed from the extruder by heating, mixing and pressurizing, and then continuously passing through the mouth die in a flowing state.Most thermoplastics and rubbers can be processed by this method. It is widely used in petrochemical, machinery manufacturing, agriculture, construction and etc.
Twin-screw extruder is developed on the basis of single screw extruder, which avoids the disadvantages of single screw extruder such as poor feeding and poor plasticization. In a twin screw extruder, the raw material is added by the feeding device through the feeding port, and some additive materials also need to be added through the feeding port in the middle of the barrel, and the materials are melted and conveyed by the double screw to reach the machine out of the head opening die.Widely used in the processing of tubes, plates and profile products.
