Pressure Thermoforming Services
PRESSURE FORMING - is a process that closely resembles vacuum forming. As in the vacuum forming process, a flat thermoplastic sheet is formed into a 3-dimensional part. However, the pressure used in pressure forming is about 3 times that of the pressure required for vacuum forming. The benefits of the pressure forming technique are: sharper edges and corners; greater detail possible; lower tooling cost than injection molding; multiple surface textures are possible on one part; and, molded logos and lettering can be incorporated onto the part's surface.
Thermoforming is a manufacturing process used for making thermoplastic sheet or film. In this process thermoplastic sheet is formed into three-dimensional shapes by clamping the sheet in a frame, heating the sheet to make to soft and then applying differential pressure to make the sheet conform to the shape of a mold or die. The sheet or film is heated between infrared natural gas or other heaters to its forming temperature.
