Principle of the blister molding machine: blister molding is also called 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 blistering into a variety of shapes of the vacuum cover, or attached to the surface of the product in various shapes. According to the thickness of the sheet material, it is divided into thin sheet vacuum molding and thick sheet vacuum molding.
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 piece and with a vacuum device, etc.;
Thick-sheet blister common products are: household appliances liner shells, luggage, display rack accessories, decoration, automotive interiors, bumpers, fenders, cosmetic equipment, light boxes, shells, toy car shells, industrial panels, and so on. Shell, toy car shell, industrial panels, advertising light boxes, blister logo, sanitary products, refrigerator liner, etc. Blister machine is also known as thermoplastic molding machine, is heated plasticized PVC, PE, PP, PET, HIPS and other thermoplastic coils suction made of various shapes of high-level packaging and decoration boxes, boxes, frames, and other products of the machine. Using the vacuum pump to generate vacuum suction, the softened PVC, PET and other thermoplastic plastic sheet through the mold suction molding into various shapes of the vacuum cover, suction molding trays, blisters and so on.
Main features:
(1) strong adaptability of product specifications with vacuum molding methods can be manufactured extra large, extra small, extra thick, extra thin products, sheet material can be as thin as 1 ~ 2MM, or even thinner, the product area can be as large as 10 square meters, as small as a few square millimeters, the wall thickness can be as large as 20mm, as small as 0.1mm.
(2) a wide range of products daily necessities blister packaging, small hardware blister packing, blister packaging, and so on. Packaging, small hardware blister packaging, automotive blister packaging, electronic products blister packaging, food blister packaging, cosmetics blister packaging, computer peripherals blister packaging, toys blister packaging, sporting goods blister packaging, stationery blister packaging, etc.
3) less investment in equipment
(4) easy to make molds, (plaster mold, copper molds, aluminum molds~~~~)
(5) Higher production efficiency.
(6) Save raw and auxiliary materials, light weight, easy to transport, good sealing performance, in line with the requirements of environmental protection and green packaging; can pack any shaped products, boxing without the need for additional cushioning materials; packaged products are transparent and visible, beautiful in appearance, easy to sell, and suitable for mechanized, automated packaging, easy to modernize the management, save manpower, improve efficiency. --From Hongyouxing's answer I hope you solve your problem, I'm glad to answer for you!
