1.Process characteristics of Full automatic PP thin Sheet extrusion Line
A single screw extruder without ventilation should be used and the raw materials do not need to be dried. The cooling of the PP layer is slower, and the coefficient of thermal expansion is large, so the opening of the mold mouth can be smaller. When producing thick plates, if you notice that the middle roller of the calender has air bubbles close to the roller, the plate surface will be Y-shaped, and you have to depressurize and deflate several times.
