The construction of the blow molding machine: extruder, material tube, fixture organization and air blowing inspection system software.
Principle of Blow Molding Machine: The plastic is melted in the screw extruder and quantitatively analyzed and extruded. Then, according to the tube forming, the air blowing inspection system software blower water is cooled, and then the traction machine organized by the chuck is used to pull the belt at the required rate. Winding it into a disk.
Dongguan blow molding products are also called hollow blow molding, and this development trend is fast plastic granulation. The tubular plastic parison obtained by extrusion or injection molding of thermoplastic resin is heated in a water bath (or warmed to soft condition), placed in the mold, and immediately after the mold is closed, the parison is filled with air compression to make the plastic parison. Inflated and pressed close to the inner cavity of the grinder, and cooled by water to obtain a variety of hollow crafts. The manufacturing process of blown plastic film is very similar to the blow molding of hollow handicrafts in basic principle, but it does not use abrasive tools. From the perspective of technical classification of plastic granulation, the forming process of blown plastic film is generally squeezed. in. The blow molding process was initially used to produce low density polyethylene vials during World War II. In the middle and late 60s, with the advent of polyethylene plastics and the development trend of blow molding machines, blow molding technology was used. The volume of hollow vessels has reached more than a thousand liters, and some manufacturers have selected motion control systems. Blow-molded plastics are high-pressure polyethylene, polyethylene, polypropylene, polyester, etc., personal income when hollow containers are commonly used as industrial packaging plastic packaging containers.
