Rubber Extruder Screw: Its function is to make the rubber material gradually become linear movement with the screw rotation movement, approaching to the direction of the head, and matching with the machine body to complete compression heat, softening mixing, and mixing rubber material.
Rubber Extruder Barrel: Containing screw rotating in the barrel. When the screw rotates the thread to push the extruded material to move forward, the external heating conducts heat to the material by the cylinder, coupled with the gradual reduction of the screw volume, making the material suffer several force such as extrusion, turnover and shear, finally the material is evenly mixed and plasticized into molten viscous flow to complete the plasticizing work.
The use of pins can make the mechanical processing of rubber extruder more effective, and it can shear and stir the flow of rubber material, which is a very efficient and energy saving processing process. The screw produced by our company has a unique geometric structure, which enables to complete difficult plasticizing, mixing and extrusion processing. The common screw is made of 38CrM0AIA material with nitriding treatment on its surface. There is also alloy screw with better use effect and longer service life, its surface sprayed with special alloy powder which is of wear resistance and high corrosion resistance.
Our company is specialized in manufacturing and selling pin type cold feed extruder screw barrel, hot feed extruder screw barrel etc. and their accessories products, which are widely used in extrusion of various rubber products and providing glue for the calender, also can be used for encapsulating and filtration of rubber impurities of extrusion rubber hose, film, inner tube, tire surface, wire and cable.
