Plastic blowing

  • Hollow blow molding, a rapid process of plastic processing. During the Second World War, the blow molding began to be used to produce low density polyethylene flask. In the late 50s, with the birth of high density polyethylene and the development of blow molding machine, blow molding technology has been widely used.The volume of the hollow container can reach thousands of liters, and some of the production has been controlled by computer.
  • The plastics for blow molding are polyethylene, polyvinyl chloride, polypropylene, polyester and so on. The hollow containers are widely used as industrial packaging containers. The blow molding can be divided into extrusion blow molding and injection blow molding, and the newly developed multi layer blow molding and tensile blow molding are newly developed.
