What is an injection blow molding machine?

Release date:2017-06-10 00:00 source: Click:

Automatic blow molding machine, also known as hollow blow molding, a rapid development of plastic processing methods. 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 parison 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. Blown film manufacturing process in principle and hollow products blow molding is very similar, but it does not use mold, from the point of view of the classification of plastic processing technology, blown film molding process is usually included in extrusion. Blow molding technology began during the Second World War for the production of low-density polyethylene vials. In the late 50s, with the birth of high-density polyethylene and the development of blow molding machine, blow molding technology has been widely used. Hollow containers can be thousands of liters in volume, and some have been computerized. The plastics used for blow molding machines include polyethylene, polyvinyl chloride, polypropylene, polyester, etc. the hollow containers obtained are widely used as industrial packaging containers.

According to parison making methods, blow molding can be divided into extrusion, blow molding and injection molding, which are newly developed with multi-layer blow molding and stretch blow molding.

Injection molding machine is a combination of injection molding machine and blow molding machine, including plasticizing mechanism, hydraulic system, control electrical equipment and other mechanical components. The common types are three station injection molding machines and four station injection molding machines. The three station machine has three working stations: Prefabricated parison, blow expanding and demoulding, each station is separated by 120 degrees. Four station machine is more pre molding station, each station is separated by 90 degrees. In addition, there are two stations separated by 180 degrees double injection molding machine. Injection molding machine produced plastic containers of precise size, without two processing, but the cost of mold is higher. Www.kautas.com
