What is the definition of blow molding machine industry? Blow molding, also known as hollow blow molding, is a rapidly developing method of plastics processing. 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. The definition and classification of blow molding machine are as follows. 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 suitable for blow molding are polyethylene, polyvinyl chloride, polypropylene, polyester, etc. the hollow containers obtained are widely used as industrial packaging containers
Blow molding machine industry definition
Hollow blow molding machine Market Research Report shows that after the liquid plastic spray, using machine blowing out of the wind, the cavity is blowing plastic body attached to a certain shape, so as to produce products, this machine is called blow molding machine. The plastic is melted and extruded in a screw extruder, then molded by a membrane, cooled by a wind ring, and then pulled by a tractor at a certain speed. The winder rolls it into a coil.
Blow molding machine industry classification
Hollow blow molding machine can be divided into extrusion blow molding machine, injection blow molding machine and special structure blow molding machine three major categories. Stretch blow molding machines are available in each of these categories. Extrusion blow molding machine is a combination of extrusion machine and blow molding machine and a clamping mechanism, the extruder and the parison head and blowing device, a clamping mechanism, the parison thickness control system and a transmission mechanism. Parison head is an important component of the decision quality of blow molding products, usually have a side feeding type die head and central feed type die head. While the use of large blow molding products accumulator type mould head. The minimum volume of the storage cylinder is 1kg, and the maximum is 240kg. Parison thickness control device used to control parison wall thickness, the control point of up to 128 points, usually 20~30 points. Extrusion blow molding machine can produce hollow products with volume ranging from 2.5ml to 104l.
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.
Special structure blow molding machine is a blow molding machine with sheet material, molten material and cold billet for parison blow molding with special shape and use. Because of the different shapes and requirements of the products, the structure of the blowing machine is different. Www.kautas.com
