Plastic thermoforming machine, also known as blister machine, taking the use of thermoplastic physical properties, for the production of thermoplastic products. Usually there are heating station, forming station, cutting station and stacking station composition. under the control of PLC, so that all stations work together to produce high quality plastic products.
Plastic thermoforming (blister) technology, is the process of thermoplastic sheet (plate) material into various products of plastic processing technology. First, the plastic sheet (plate) material is heated in the heating furnace to the soft status, and then placed in the forming mold, under the external forces (vacuum, positive pressure or machinical force), so that it closely adhere to the surface of the mold, forming and bonding surface detailed shape.After cooling shaping, trimming and other processes, get the desired products.
Plastic thermoforming (blister), usually used in the manufacture of thermoplastic products.Products with large forming surface and uniform thickness can be produced by this method.Compared with injection molding, it has the advantages of high production efficiency, low equipment investment and low mold cost.Suitable engineering plastics including polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS), acrylonitrile – butadiene – styrene (ABS), polymethyl methacrylate (PMMA) and polyethylene terephthalate (PET), etc., material thickness less than 1.5 mm is often called chips, above is called the thick sheets.
Thermal forming process consists of vacuum forming method, pneumatic forming method, die forming method, plunger – assisted pressure forming method, solid – phase forming method and double – sheet thermal forming method.According to different products, different materials and different thickness, choose the appropriate forming process.
Products that can be made, such as beverage cup, fruit boxes, fast food box, egg holder, electronic tray, car interior, agricultural car roof, refrigerator liner, logistics transport pallets and so on, thermoforming is widely used.
With the continuous improvement of the automation technology, a variety of automatic blister machines boom.
2 heating 1 forming thermoforming machine，also known as double thick sheet thermoforming machine, is mainly used for making plastic products with double layer structure, such as logistics pallets, shelf pallets and logistics turnover boxes which need to bear load, and containers which need heat preservation and heat insulation. It is suitable for most thermoplastics.
SH series semi-auto thick plate thermoforming machine is used for forming plastic which thickness is below 12mm. Including heating station, forming station, the machine needs to be equipped with additional trimming station, vacuum system and hydraulic system. The machine is used for making large plastic products such as traveling case, bathtubs, pit tubs, refrigerator inner and so on.
In-mold cutting servo thermoforming machine integrates punching station into forming position, which greatly improves the precision of products and simplifies the structure of the machine. It usually includes heating station, forming punching station and stacking station. Used to produce plastic products with thickness below 1.5mm, such as fast food box, fruit box and so on.
Small semi-auto thermoforming machine, namely sampling thermoforming machine is designed for small batch or samples products. It takes the principle of thermoplastics vacuum thermoforming. The machine has light weight, small size and easy operation. The heating station and forming station work at the same time, with high production efficiency.
The is the most advanced cup making machine in China, which adopts positive and negative pressure forming and in-mold punching structure, and has the characteristics of high speed, high efficiency and convenient packaging.Suitable for plastic cups with material thickness of less than 2.5mm and forming height of less than 200mm.
3-station automatic positive and vacuum plastic thermoforming machine, used for thermoforming of thermoplastic plastic with thickness of 0.2-1.5mm or less, widely used, such as food box, fruit box, egg tray, electronic tray, etc.
The equipment is used for making PVC plastic wall panels, decorative interior wall panels and other materials of plastic wall panels. As long as the replacement mold, it can be used to make large thin sheet plastic parts.
1 heating 2 forming thermoforming machine is used for the production of PE, PP, PVC, PS, ABS, PMMA and other conventional engineering plastic products, such as electronic pallet, vehicle interior decoration board, decorative wall panel and other large area products.
Split type hydraulic thermoforming machine is used for the production of plastic products with thickness of 1-2.5mm coil material, high speed and high efficiency. Such as electronic tray thermoforming, vehicle interior panel thermoforming, decorative wall panel thermoforming, tub thermoforming, refrigerator liner thermoforming and other larger area products thermoforming.
