[0002] Injection blow molding machine (abbreviated as injection blow molding machine) is a device that makes plastic particles into hollow containers through injection blow molding process. Its specific working process is as follows: the molten material is injected into the injection mold to form a parison, and the parison is placed in the blow mold, and the parison in the blow mold is blown into a product using compressed air.
