The bottle blowing machine is a kind of plastic particles by blow molding process will be made into hollow container equipment, currently more common types include, forming a PP and PE hollow extrusion blow machine, using PET, PC or PP two molding injection stretch blow molding machine, and the newly developed multilayer hollow extrusion blow molding and stretch blow molding.
At present, most of the bottle blowing machine is still the two step bottle blowing machine, that is, we must first make the plastic raw material into the bottle embryo, and then blow it. Now commonly used is the PET material of environmental protection plastic. Blow molding machine: after the liquid plastic is sprayed out, the wind is blown by the machine, and the mold is blown to a certain shape cavity to make the product. This machine is called blow molding machine. It is also a kind of bottle blowing machine, that is, hydraulic bottle blowing machine.
Tubular plastic parison of thermoplastic resin by extrusion or injection molding obtained, while hot (or heated to the softening state), placed in the mold, die immediately after the bottle is filled with compressed air, so that the plastic parison blowing mold and clings to the inner wall, the cooling and demoulding, obtain various hollow products.
