Blow molding products, and with a shiny surface, or in the processing process, the products formed on the surface of engraving or carving patterns. Applicable to the majority of blow molding of plastic, so its in a variety of plastic molding processes account for a large advantage. As a new materials and new forming processes, blow molding process will be continuous development of the plastics industry to become the development trend of the future.
