Blow molding machine is a kind of hollow container made of plastic particles through a blow molding process. It is currently a relatively common model including a hollow extrusion blow molding machine that uses PP and PE for one-time molding, and uses PET, PC or PP for two moldings. The injection stretch blow molding machine, as well as the newly developed multi-layer hollow extrusion blow and stretch blow molding.
At present, most of the blow molding machines are still two-step blow molding machines, that is, plastic raw materials must be first made into preforms, and then blown. Nowadays, environmentally friendly plastics made of PET are commonly used. Blow molding machine: After spraying liquid plastic, the wind blown by the machine is used to blow the plastic body to a certain shape of the cavity to make a product. This kind of machine is called a blow molding machine. It is also a kind of bottle blowing machine, also called bottle blowing machine. The plastic parison obtained by extrusion or injection molding of the thermoplastic resin is placed in the center while it is hot (or heated to a softened state), and compressed air is injected into the parison immediately after the mold is closed to inflate the plastic parison. Closely stick to the inner wall and demould after cooling to obtain various hollow products.
