Volume has used computer control up to thousands of liters, some production.Plastics suitable for blow molding have polyethylene, polyvinyl chloride,
Polypropylene, polyester etc., the hollow container of gained are widely used as industrial packaging container.According to parison production method, blow molding can be divided into
Extrusion-blown modling and injection-blow molding, what new development was got up has multilayer blow moulding and stretch-blow.
The tubular plastic parison that thermoplastic resin is squeezed out or is injection moulded, while hot (or being heated to soft state),
It is placed in split cavity, is passed through compressed air after die closing in parison immediately, make plastic parison inflation and be tightly attached on mould inner wall,
Through cooling and demolding to get arrive various hollow products.The manufacturing process of inflation film is blow molded ten split-phases with hollow product in principle
Seemingly, but it does not use mold, and the angle classified from plastic processing technology, the moulding process of inflation film is usually included in extrusion.
Traditional plastic tube directly carries out cooling and shaping after the completion of blow molding typically in mold, traditional
Cooling means is relatively simple, and the speed that plastic tube is cooled and shaped is slower, may make to the size of plastic tube when cooling
At certain deviation, and accurate requirement is needed for the size of some medical plastic expects pipes, traditional cooling and shaping method compared with
Hardly possible meets.
