Basic Information Of Extrusion Blow Molding Machine
- Jan 04, 2018 -

Extrusion blow molding machine, also known as hollow blow molding, a rapid development of plastic processing methods. Thermoplastic resin extruded or injection-molded tubular plastic parison, hot, placed in the mold, the mold immediately after the introduction of compressed air in the parison, the plastic parison inflated and close to the mold wall On the cooling demoulding, that is, a variety of hollow products. Blown film manufacturing process in principle and the hollow product is very similar to the blow, but it does not use the mold, plastic processing technology from the classification point of view, the blown film molding process is usually included in the extrusion. During the World War II blow molding process began to be used to produce low-density polyethylene vials. The late 50's, with the birth of high-density polyethylene and the development of blow molding machines, blow molding technology has been widely used. Hollow container volume up to thousands of liters, and some production has been using computer control. Suitable for blow molding of plastic polyethylene, polyvinyl chloride, polypropylene, polyester, the resulting hollow containers are widely used as industrial packaging containers. According to parison production methods, blow molding can be divided into extrusion blow molding and injection blow molding, the newly developed multi-layer blow molding and stretch blow molding.
