Blow molding machine is a rapid development of plastic processing machinery and equipment, can quickly blow PE and other hollow products of a variety of materials, so the major enterprises are widely respected have the intention to purchase. 
One, the principle of hollow blowing machine
Plastic blow molding machine is a liquid spray out, make full use of the machine to blow out of the wind, blowing plastic body attached to the corresponding shape of the cavity, plastic parison strike placed in split cavity, mold closing immediately after injection of compressed air within the parison, make plastic parison swell and clingy wall in the mold, after cooling off membrane, hollow namely get all kinds of products. It is often used for blowing PE and hollow products of various materials, such as barrels, drums, beer containers, tool boxes, lamp covers and so on.
Two, hollow blow molding machine structure characteristics
The structure characteristics of hollow blow molding machine is mainly composed of extruder, head, hydraulic system, clamping system, electrical control system, charging system, automatic clamping and other parts of the combination, the basic framework is mainly composed of power part and heating part of the two structures. The power part is mainly composed of frequency converter and power output motor, which is the main working parts for energy transfer and wind power output. The heating part is composed of electromagnetic heater and bracket part, which can be used to heat the plastic that needs to be blown by the wind to maintain its long-term softening characteristics.
Three, blow molding machine production process
Extruder is the plastic particles heating, melting, mixing after the push into the mold head; The mold head will melt the plastic into a prefabricated embryo; After entering the mould, the mould is cooled and blow-molded with the blowing system to obtain the pre-product of the final product. After that, there may be trimming, welding and other processes.
