Plastic machine forming technology principle

  Bag mechanical blister molding is also called thermoplastic molding, this molding process is mainly the use of vacuum pump vacuum suction generated after heating and softening PVC, PET, PETG, APTT, PP, PE, PS and other thermoplastic sheet through the mold blister into various shapes of vacuum cover, or attached to the surface of various shapes of products. Blister is divided into thin sheet blister and thick sheet blister according to sheet thickness.

The main structure of the machine is composed of feeding, pulling, up and down electric heating furnace, lower brake, multi-function adjustable size, lower die plate, upper die, upper brake, knife brake, slice, release and equipped with vacuum device;

The thick sheet blister common products are: household appliances inner shell, luggage bags, display accessories, decoration, automotive interior, bumper, fender, beauty equipment, light box shell, toy car shell, industrial panels, advertising light box, blister LOGO, bathroom products, refrigerator inner shell and so on.

Blister molding technology

Blister molding technology, that is, plastic sheet (plate) thermal molding processing technology, is one of the plastic secondary processing industrial technologies. It is different from injection molding, extrusion and other one-time processing technology, not for plastic resin or particles heated molding or continuous molding with the same cross section die; It is not the use of machine tools, tools and other mechanical processing means to cut down a part of the plastic material to obtain the required shape and size, but for the plastic sheet (plate) material, heating, the use of mold, vacuum or pressure to deform the sheet (plate) material, to achieve the required shape and size, supplemented by supporting processes, to achieve the purpose of application.

Blister molding equipment includes clamping system, heating system, vacuum and compressed air system and molding mold and other parts.
