Material selection and granulation: Select high-quality plastic particles, such as polyethylene, polypropylene, polyvinyl alcohol, etc., as raw materials. The quality of these raw materials is directly related to the quality of Z's final product
Plastic barrel molding: This process usually includes two processes: injection molding and blow molding. Injection molding process involves injecting heated and melted plastic materials into a product mold, applying pressure to fully compress the material in the mold, and forming the desired product shape. The blow molding process involves injecting heated and melted plastic material into a blow molding mold, cooling and solidifying it, and then using a blow molding machine to remove the product from the mold. At this point, the shape of the product has been fully realized.
