About the principle of automatic blow molding machine

onAutomatic blow molding machineprinciple:

Plastic hollow containers are widely used in beverage, medicine, cosmetics, food and chemical industries due to their light weight, low price, and high safety. They have attracted more manufacturers to choose plastic containers to replace glass containers in the past. Now the most advanced equipment, molds and materials in the plastics industry are unfolding in front of us. New technologies and new applications are emerging one after another, and the field of plastic hollow molding is also fruitful. Blow molding machine is a kind of equipment that uses blow molding technology to make plastic particles into hollow containers. Nowadays, the more common models include one-shot hollow extrusion blowers that use PP and PE, and use PET, PC or PP twice. Molded injection stretch blow molding machine, as well as the newly developed multi-layer hollow extrusion blow and stretch blow molding.

Now mostAutomatic blow molding machineIt is also a two-step blow molding machine, that is, it is necessary to first make the plastic material into a preform, and then blow it. Environmentally friendly plastics made of PET are commonly used nowadays. The blow molding machine uses the wind blown out of the machine to blow the plastic body into a certain shape of the cavity after the liquid plastic is sprayed out, and then the product is made. This kind of machine is called a blow molding machine. It is also a kind of blow molding machine, namely hydraulic blow molding machine.

The tubular plastic parison obtained by extrusion or injection molding of the thermoplastic resin is placed in a split mold while it is hot (or heated to a softened state). After the mold is closed, compressed air is injected into the parison to blow the plastic parison. It expands and clings to the inner wall of the mold, and after cooling and demolding, various hollow finished products are obtained.
