A more specialized plastic processing method for processing thermoplastic sheets into various articles. The sheet is heated on the frame to a softened state, and is pressed against the profile of the mold by an external force to obtain a shape similar to the profile. After cooling and setting, it is trimmed to form a product. This process is also used for rubber processing. In recent years, thermoforming has made new advances, such as continuous production techniques from extruded sheets to thermoforming.
In the market, there are more and more thermoformed products, such as cups, saucers, food plates, toys, helmets, as well as automotive parts, architectural decorative parts, chemical equipment and so on. Compared with injection molding, thermoforming has the advantages of high production efficiency, low equipment investment, and the ability to manufacture products with a large surface area. The plastics used for thermoforming are mainly polystyrene, polyvinyl chloride, polyolefins (such as polyethylene, polypropylene), polyacrylates (such as polymethyl methacrylate) and cellulose (such as nitrocellulose, Plastics such as cellulose acetate, etc., are also used in engineering plastics (such as ABS resin, polycarbonate). There are many types of thermoforming methods, but they are basically combined or modified based on three methods of vacuum, air pressure or mechanical pressure.
