entering into the extruder in general metal, polymer, ceramic, or food raw materials of a machine melt pressure and temperature. the extruder used to mold plastic industry to a large part, though, for example they consist of planetary extruders feeding and the front screw portion. plastikig feeding group of products bearing the group in front screw cools the planet, the effect of high pressure and temperature of the goods passes from the front screw melt it in powder form. The majority of PVC film production in Europe, although there are these types of extruded production in the Far East generally known as the extruder screw is made of extruded. PVC situ- ation is transmitted at a higher temperature in the extruder and sausage the size of these passes without air.
