Plastic Molding
VP20TS
Many items used in our daily lives are made of plastic. In order to process this material, some techniques can be used, such as: plastic injection (automobiles, electronics, toys, household items and construction), blow molding (packaging and toys), plastic extrusion (packaging and toys) pressing (cars and white goods) and accessories (mold bases, hollows, hot runners, pins and stripper plates).
