Plastic molding processing equipment is developed on the basis of rubber machinery and metal die casting machine. Since the emergence of polymer injection molding process and simple molding equipment in the 1870s, as an industry, until the 1930s to obtain rapid development, plastic molding processing equipment gradually commercialized, injection molding and extrusion molding has become an industrial processing method. Blow molding is second only to injection molding and extrusion of the third largest plastic molding method, is also the fastest development of a plastic molding method.
