An extrusion blow molding machine is a machine that makes products by blowing out liquid plastic and then using the wind force blown out by the machine to blow the plastic body attached to a particular shape of the die cavity. The plastic is melted and extruded quantitatively in the screw extruder, then shaped through the mouth die, then there is a wind ring blowing air cooling, then there is a traction machine to tract at a certain speed, and the winding machine will wind it into a roll.
Extrusion blow molding machine hollow blow molding technology, a rapidly developing plastic processing method, thermoplastic resin by extrusion or injection molding to obtain the tubular plastic blanks, while hot, placed in the folio mold, immediately after the closure of the mold in the blanks into the compressed air, so that the plastic blanks blowing and cling to the inner wall of the mold, after cooling off the mold, that is, to obtain a variety of hollow products. The manufacturing process of blown film is very similar to hollow products blowing in principle. Still, it does not use molds, and from the perspective of plastic processing technology classification, the molding process of blown film is usually included in extrusion.
