The difference between positive and negative pressure suction machine suction machine
One is blister machine, one is blow molding machine, and another is blow molding. For example, a one-time plastic cup, three are in use.
Positive and negative pressure suction machine more cost saving, higher precision, the latest research and development of plastic machinery in 2014 Dili automatic multi station negative pressure suction machine, the processing of sheet thickness between 0.2--2mm.
The difference between positive and negative pressure suction machine suction machine, suction machine is only the function of positive and negative pressure suction blister, plastic and plastic blow molding has the function of negative pressure suction machine; suction force is low machine cost, the structure is more simple.Plastic molding machine principle: plastic molding called thermoplastic molding, the molding process is mainly produced by vacuum vacuum pump after PVC, PET, PETG, APTT, PP, PE, PS and other thermoplastic plastic sheet after mold suction into various shapes of cover, surface or cling to various shapes of products. Blister according to sheet thickness is divided into thin film blister and thick film blister.The main structure of the machine consists of feeding, drawing materials, heating up and down electric heating furnace, lower gate, multifunctional adjustable size, lower die plate, upper die, upper gate, knife brake, slice, film and vacuum device;Thick sheet vacuum common products: household appliances, luggage rack, liner shell fittings, decoration, car interiors, bumper, fender, beauty equipment, lamp box shell, toy car shell, industrial panel, advertising light boxes, plastic LOGO, sanitary products, refrigerator liner etc..
