Study On Screw Design of Single Screw Extruder

Among single screw extruders, the pin screw extruder is suitable for the extrusion screw of wood-plastic composite extrusion system, because the pin can be cut on the material flow and repeatedly to form a new interface and then repeatedly re-oriented so that the heat of the liquid can be passed to the solid phase in time. Thus the screw pin has a good ability of mixing, dispersion and plasticizing.  The screw can be extruded with low-temperature under the conditions of the same formula and the critical of the screw can be increased at the same time, so that the production will be increased .Besides, the appearance and performance of the extrusion products are better than ordinary single screw extruders.
