The price of kneeling single station hollow blow molding machine;
It began to be used in the production of LDPE 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 suitable for blow molding are polyethylene, polyvinyl chloride, polypropylene, polyester, etc. the hollow containers obtained are widely used as industrial packaging containers.
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. Blowing technology during the second world war,
The blow molding machine that our unit buys is one hundred and ten thousand, have formal invoiceMoulding (blow), 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.
