QQ 194535455 Abstract The plastic rod extruding machine abbreviation extrude (also name extruding press), it is an important implement of the plastic reclaiming process. The extrude is made of five parts? the part of extruding;the part of passing;the head;the system of heading and cooling;the electrical control major part of the extrude is the part extruding,it is the most use of shear ,rend and pinch the plastic,under fastness pressure,continuous send plastic to the head ,it made up of fill device ,screw ,barrel ,liner and so on,And the screw is disport of single screw ;double screw ;ponent material of liner is 38CrMoAlA. The part of passing is driving the screw rotation and basic the need of the art factitious process to adjustment the screw royal .The part of passing is made of electrical engineering and reducer. The head is the extruding machine formed part .Its function is :Causes the sizing material to e the translation by the helical motion ;under the certain pressure ,extrudes the sizing materials which need the shape the half-finished product. The system of heating and cooling is for the plastic well extrusion ,we control the temperate to prevent the temperate too low or born. The e
