Thermoforming General Information
Thermoplastic sheet processed into various products of a special plastic processing method. Sheet clamp to the frame heat to soften, external force, making it close to the mould surface, similar to to get connected with the surface shape. After cooling, the finished products. This process is also used in rubber processing. In recent years, the hot new progress has been made, for example from the continuous production of extruded sheet thermoforming technology.
In the market, hot forming products more and more, such as cups, plates, food trays, toys, helmets, car parts, building decoration, chemical equipment, etc. Thermoforming and injection molding, high production efficiency, low investment and produces larger surface area of the product and so on. For thermoforming of plastic main with PS, PVC, polyolefin (polyethylene, polypropylene), poly-acrylic (Poly methyl methacrylate) and fiber (such as nitrocellulose, cellulose acetate and so on), plastic, for plastics (such as ABS resins, polycarbonate). Thermoforming there are several ways, but is basically to vacuum, pneumatic or mechanical pressure based on three methods to be combined or modified from.
