Hollow blow molding is divided into injection blow molding, extrusion blow molding and stretch blow molding . Injection blow molding is to first make plastic into a bottomed parison by injection molding, and then move the parison into the blow mold for blow molding. Forming. In the extrusion blow molding process, the tube blank is directly extruded by the extruder and suspended in a pre-separated cavity directly under the head; when the drooping parison reaches the specified length, the mold is closed and the mold is closed. The incision of the mold cuts the tube blank; the compressed air is introduced from the small hole of the mold parting surface, and the parison is inflated and pressed against the mold wall to form; the pressure is maintained, and the product is opened after the product is cooled and shaped in the cavity to take out the product. There are many kinds of thermoplastics used for hollow blow molding. The most commonly used raw materials are polyethylene, polypropylene, polyvinyl chloride and thermoplastic polyester. They are commonly used to form packaging containers for various liquids, such as various bottles and barrels.
