Automatic blister packaging machine (also known as thermoplastic molding machine) is used to absorb heat-plasticized PVC, PE, PP, PET, HIPS and other thermoplastic coils into various shapes of advanced packaging and decoration boxes, frames and other products. machine. Using the vacuum suction generated by the vacuum pump, the heated and softened thermoplastic sheets such as PVC and PET are molded into various shapes of vacuum covers, blister trays, blisters, etc. through molds.

　　1. Principle of blister forming machine

　　Blister molding is also called thermoplastic molding. This molding process mainly uses the vacuum suction generated by the vacuum pump to heat and soften PVC, PET, PETG, APTT, PP, PE, PS and other thermoplastic sheets through molds. Vacuum covers of various shapes, or attached to the surface of products of various shapes. According to the thickness of the sheet, blister is divided into thin sheet blister and thick sheet blister.

　　At present, the common product sheet blisters on the market include: daily necessities blister packaging, hardware blister packaging, automotive supplies blister packaging, electronic products blister packaging, food blister packaging, cosmetics blister packaging, computer peripheral equipment blister packaging, Blister packaging for toys, blister packaging for sporting goods, blister packaging for stationery, etc.

　　The main structure of the machine is composed of feeding, pulling, upper and lower electric heating furnaces, lower gate, multi-functional adjustable size, lower mold plate, upper mold, upper gate, knife gate, slicing, releasing and equipped with vacuum devices, etc. ;Pneumatic device is the main power source, and the pulling and feeding of the film adopts electric, reducer, time relay, intermediate relay, travel switch and other electrical appliances to form a fully automatic control system.

　　The common products of thick sheet blister include: household appliances liner shell, luggage, display rack accessories, decoration, car interior, bumper, fender, beauty equipment, light box shell, toy car shell, industrial panel, advertising light box, Plastic LOGO, bathroom products, refrigerator liner, etc.

　　2. Main application of blister machine

　　Plastic packaging industry (blister packaging, plastic, batteries, toys, gifts, hardware, home appliances, electronics, stationery, decoration); food packaging industry (fast food boxes, fruit trays, biscuit boxes); pharmaceutical industry (pill packaging, tablet packaging) ; Industrial cooling tower cooling water deflectors, etc.; three-dimensional relief patterns for decoration, plastic ceilings, wall panels, automotive materials, sanitary equipment and other manufacturing industries.

　　Suitable for the production of various color sheets: polyethylene PS, polyvinyl chloride PVC, plexiglass, abs, polymethyl methacrylate; flocking sheets; environmentally friendly sheets APET, PET, PP, etc.; photodegradable materials; biodegradable Materials and other plastic products.

　　3. Main features of blister machine

　　Strong product specification adaptability Blister molding method can be used to manufacture various products of extra large, extra small, extra thick, and extra thin. The sheet can be as thin as 1~2MM, or even thinner. A few square millimeters, the wall thickness can be as large as 20mm, as small as 0.1mm;

　　Blister packaging for daily necessities, plastic packaging for small hardware, plastic packaging for automotive supplies, plastic packaging for electronic products, plastic packaging for food, plastic packaging for cosmetics, plastic packaging for computer peripheral equipment, plastic packaging for toys, sporting goods Blister packaging, stationery blister packaging, etc.;

　　Less equipment investment; convenient mold manufacturing (plaster mold, copper mold, aluminum mold); high production efficiency. Saving raw and auxiliary materials, light weight, convenient transportation, good sealing performance, in line with the requirements of environmentally friendly green packaging; can pack any special-shaped products, without additional cushioning materials for packing; the packaged products are transparent and visible, beautiful in appearance, easy to sell, and suitable for Mechanized and automated packaging facilitates modern management, saves manpower and improves efficiency.

　　Commonly used thermoforming plastics and performance plastics can be divided into two categories: thermoplastics and thermosetting plastics according to their heating behavior. Most of the materials used for thermoforming are thermoplastic materials. Regardless of single-layer or multi-layer composite plastic sheet (board) used for thermoforming processing, it must have the following technological properties: plastic memory; thermal stretching; thermal strength; forming temperature.
