Blow mould also known as hollow blow molding, a rapidly growing plastic processing method. The blow molding process began to be used to produce low density polyethylene vials during the Second World War. In the late 1950s, with the birth of high-density polyethylene and the development of blow molding machines, blow molding technology was widely used. The volume of hollow vessels can reach thousands of liters, and some production has been computerized. Suitable for blow molding plastic polyethylene, polyvinyl chloride, polypropylene, polyester, etc., the resulting empty container is widely used as industrial packaging containers. According to the method of making billet, blow molding can be divided into extrusion blow molding and injection blow molding, the new development of multi-layer blow molding and stretch blow molding.
