Brief introduction about the film blowing machine

    Blow moulding,also known as hollow blow molding.This is a kind of rapid development of plastic processing methods. Thermoplastic resin by extrusion or injection molding that gets tube plastic parison , hot (or heated to softening state), put into the die sinking, after mold closing ventilation with compressed air into the parison immediately , to make plastic parison swell and keep close to the mold,by cooling and demoulding ,at last, the hollow products will be get.The blown film manufacturing technology is similar to the hollow products blowing on the principle .
    From the classification of plastic processing technology ,the forming processes of the blown film is usually included in the extrusion unit. During the second world war, the blowing process started to be used for the production of low density polyethylene small bottles. In the late of 50 s, with the outing of  high density polyethylene and the development of the blow molding machine, the blow molding technology has been widely used. The volume of the hollow container can up to thousands of liters, some production has adopted computer control. The plastics are suitable for blow molding includes polyethylene, PVC, and polypropylene ,Polyester, etc., the empty container are widely used in industrial packaging container.
    According to the methods of making parison, the blow molding can be divided into the extrusion blow molding and injection blow molding ,and the other, the multi-layer blow molding and stretch blow molding is developed recently.
