Introductions
PET material because of its exceptional performance, are generally used two-step molding process, by the plastic injection molding machine to produce a 24-hour After cooling, the internal molecular structure of their re-arranged in an orderly manner, and blowing for the next step to create good conditions, so that more excellent blowing performance products. Such as the famous Coca-Cola Company is currently using this technology.
Plastic injection molding machine composed of imported advanced hydraulic components. System pressure is controlled by proportional valve. According to users demand, a quick mold clamping device and fast-respond excellent control valves also can be fitted on the unit.
