The three categories of the blow molding machine

Injection blow molding machine, the special structure of blow molding machines and extrusion blow molding machine three categories can be divided into three classification of blow molding machines, blow molding machines. Stretch blow molding machine, however, can be attributed to each class. Injection blow molding machine is a combination of injection molding machines and blow molding machines, including plasticizing mechanism, hydraulic system, electrical control and other mechanical parts. Common type of three-position injection blow molding machine and four-station injection blow molding machine. Three-position machine preform blow and stripping three stations, each station separated by 120 °. The four-station machine is more of a pre-forming station, each station separated by 90 °. In addition, there are 180 ° apart station duplex injection blow molding machine. Injection blow molding machine to produce precise size plastic containers without the need for secondary processing, but the high cost of mold. The special structure of the blow molding machine to melt and cold parison for blow molding sheet having a special shape and purpose of the hollow body blow molding machines. Also different due to the different shape and requirements of the production of articles in the structure of the blow molding machine. The extrusion blow molding machine extruder, blow molding machine clamping mechanism assembly the parison die from the extruder and the type, the means of blow mold clamping mechanism, the parison thickness control system and drive mechanism. The parison die is one of the important parts of decision blow moldings quality usually have side feed die and the central feed die. The large products blow the use of storage material cylinder parison die. The parison thickness control means for control of parison thickness control point of up to 128 points, typically 20 to 30 points. Storage material cylinder volume is a minimum of 1kg, up to 240kg.
