Principle of plastic molding machine: plastic molding, also known as thermoplastic molding, this molding process is mainly the use of vacuum pumps to produce vacuum suction will be heated and softened PVC, PET, PETG, APTT, PP, PE, PS and other thermoplastic plastic sheet through the mold suction molding into a variety of shapes of the vacuum cover, or attached to the surface of a variety of shapes of products. According to the thickness of the sheet is divided into thin sheet and thick sheet vacuum molding.
The common products on the market are: daily necessities, small hardware blister packaging, automotive blister packaging, electronics blister packaging, food blister packaging, cosmetics blister packaging, computer peripheral equipment blister packaging, toys blister packaging, sporting goods blister packaging, stationery blister packaging, and so on. The main structure of the machine is composed of feeding, pulling, upper and lower electric heating furnace, lower gate, multifunctional adjustable size, lower mold plate, upper mold, upper gate, knife gate, slicing, releasing the slice and with a vacuum device, etc.; pneumatic device as the main source of power, and its pulling slice, sending the slice of electric power, speed reducer, time relays, intermediate relays, travel switches and other electrical appliances to form a full-automatic control system.
Thick sheet blister common products are: household appliances liner shell, luggage, display rack accessories, decoration, automotive interior, bumpers, fenders, beauty equipment, light box shell, toys, car shell, industrial panels, advertising light boxes, blister LOGO, sanitary products, refrigerator liner and so on.
Blister molding technology that plastic sheet (plate) thermoforming processing technology, is a plastic secondary processing industry technology. It is different from injection molding, extrusion and other primary processing technology, not for plastic resin or particles for heating molding or the same cross-section of the same cross-section of the mold continuous molding; not the use of machine tools, cutting tools and other mechanical means of processing, a part of the plastic material cut down, to obtain the required shape, size, but for the plastic sheet (plate), heating, the use of molds, vacuum or pressure to make the sheet (plate) deformation to achieve the required shape and size, supplemented by the plastic sheet (plate), to achieve the required shape and size, to achieve the required shape and size, to achieve the desired shape and size. To achieve the required shape and size, supplemented by supporting processes, to achieve the purpose of the application.
