The raw material is added into the hopper, and under the action of shear force and propulsion force generated by the screw rotation, the material is gradually plasticized and melted to form a uniform melt in the barrel. Then, the melt is pushed by the screw through the extrusion mold, and is extruded into a sheet with a certain shape and size.
Working Principle:
The raw material is added into the hopper, and under the action of shear force and propulsion force generated by the screw rotation, the material is gradually plasticized and melted to form a uniform melt in the barrel. Then, the melt is pushed by the screw through the extrusion mold, and is extruded into a sheet with a certain shape and size.
