The basic mechanism of the extrusion process is simply a screw that rotates in the barrel and pushes the plastic forward. The screw structure is a slope or slope wound on the center layer, the purpose of which is to increase the pressure in order to overcome the greater resistance.
Read MoreExtrudable plastics are thermoplastics, which melt when heated and solidify again when cooled. Therefore, heat is required during the extrusion process to ensure that the plastic can reach the melting temperature. So where does the heat of melting plastic come from?
Read MoreScrew diameter Screw diameter refers to the outer diameter of the screw, represented by D, in mm. Like a single-screw extruder, the screw diameter of a twin-screw extruder is an important technical parameter, and its size indicates the production capacity of the twin-screw extruder to a certain exte......
