The plastic forming machine (ma also called plastic molding machine) is developed on the basis of rubber machinery and metal die-casting machine. Since the polymer injection molding process and molding equipment in the 1870s, as an industry, plastic forming machine got rapid development until the 1930s, with the gradual commercialization of plastic molding equipment, injection molding and extrusion molding has become the most common industrialized processing methods. Blow molding is the third-largest plastic molding method after the injection molding and extrusion blow molding method, it is also the fastest development of plastic molding method.
