A small vacuum forming machine (also known as a thermoplastic molding machine) is a machine that sucks thermoplastic rolls such as PVC, PE, PP, PET, HIPS, etc. that are heated and plasticized into various shapes of advanced packaging boxes, frames, and other products. By utilizing the vacuum suction generated by a vacuum pump, thermoplastic plastic sheets such as PVC and PET, which have been heated and softened, are molded into various shapes such as vacuum covers, vacuum trays, and blister shells.
Principle of vacuum forming machine: Vacuum forming, also known as thermoplastic forming, is a forming process that mainly uses the vacuum suction generated by a vacuum pump to heat and soften PVC, PET, PETG, APTT, PP, PE, PS and other thermoplastic plastic sheets into various shapes of vacuum covers through molds, or attach them to the surface of various shaped products. Vacuum forming is divided into thin sheet vacuum forming and thick sheet vacuum forming according to the thickness of the sheet.
The main structure of its machine is composed of feeding, pulling, upper and lower electric heating furnaces, lower gates, multifunctional adjustable sizes, lower mold plate, upper mold, upper gate, knife gate, slicing, discharging, and equipped with vacuum devices;
Common products of thick sheet vacuum forming include: household appliance inner shells, luggage and bags, display rack accessories, decoration, car interiors, bumpers, fenders, beauty equipment, light box shells, toy car shells, industrial panels, advertising light boxes, vacuum formed logos, bathroom products, refrigerator inner shells, and so on.
The main applications of vacuum forming machines are:
1. Plastic packaging industry (vacuum formed packaging, plastic, batteries, toys, gifts, hardware, home appliances, electronics, stationery, decoration);
2. Food packaging industry (fast food boxes, fruit trays, biscuit boxes);
3. Pharmaceutical industry (pill packaging, pill packaging);
4. Cooling water guide plates for industrial cooling towers, etc;
5. Manufacturing industries such as decorative three-dimensional relief patterns, plastic ceilings, wall panels, automotive materials, and sanitary equipment.
6. Suitable for producing various colored sheets: polyethylene PS, polyvinyl chloride PVC, organic glass ABS、 Polymethyl methacrylate; Flocking sheet; Environmentally friendly sheet materials such as APET, PET, PP, etc; Photodegradable materials; Biodegradable materials and other plastic products.
