We are a Crusher machine manufacturers, why is the plastic crusher an indispensable equipment in the plastic industry?
Physical conversion utilization is environmentally friendly and economical, similar to direct utilization, and is now used by manufacturers themselves. The process is crushing - granulation - extrusion (stretching) or injection molding, etc., if necessary, add other items. The processing process of directly using plastic products is mainly a physical process, that is, the addition of additives or color masterbatches, which is basically a physical mixing process. That is, after the plastic slices or pellets are heated and melted, the injection molded products, injection molded products, or extrusion blow molding or extrusion casting films are stretched into films. Examples of injection molded products are foam packaging materials (blocks), examples of injection molded products are various plastic packaging bottles, and examples of extrusion blow molded films are multi-layer co-extruded film products such as heat shrinkable film, cling film, Examples of extrusion casting films are biaxially oriented polypropylene film BOPP and biaxially oriented polyester film BOPET and the like. Since the changes of the materials in the above process are all physical changes, their chemical structures remain unchanged, which provides convenience for the application of leftover materials. Therefore, in plastic product manufacturing plants, the scraps in production are generally crushed, extruded and pelletized or melted and then extruded and pelletized, and then put back into the production line for continued use. Because of this, plastic crushers and granulators are essential equipment in the plastics industry.
