Blowing molding machine is a kind of equipment for making plastic granules into hollow containers through blow molding process. At present, the more common models include one-shot hollow extruding machine using PP and PE, and two moldings using PET, PC or PP. The injection stretch blow molding machine, as well as the newly developed multi-layer hollow extrusion blow and stretch blow molding. Blowing molding machines are mainly divided into three categories: extrusion blow molding machines, injection blow molding machines and special structure blowing machines.
At present, most blowing machines are still two-step blow molding machines, that is, plastic raw materials must be made into preforms before blowing. Nowadays, PET plastic material is generally used. Blow Molding Machine: After the liquid plastic is sprayed out, the wind blown by the machine is used to blow the plastic body into a cavity of a certain shape to make a product. Such a machine is called a blow molding machine. It is also a kind of blower, namely hydraulic blower.
