Also known as hollow blow molding, a rapidly developing plastic processing method. The blow molding process began to be used to produce low density polyethylene vials during World War II. In the late 1950s, with the birth of high density polyethylene and the development of blow molding machine, blow molding technology has been widely used. The volume of hollow containers can reach thousands of liters, and some production has adopted computer control. Suitable for blow plastic polyethylene, polyvinyl chloride, polypropylene, polyester, etc., the empty container is widely used as an industrial packaging container. According to the production method of billet, blow molding can be divided into extrusion blow molding and injection blow molding, the new development of multi-layer blow molding and tensile blow molding.
