Vacuum Thermoforming
Vacuum thermoforming is a very economical method for producing plastic parts. This process can produce large or small parts in low quantities at a reasonable price. This involves the controlled heating of a thermoplastic material to a temperature where it is pliable enough to be altered by the shape of a mold. This mold can be made of wood, phenolic or aluminum, so tooling can be optimized depending on the properties required. In this method, the heated thermoplastic is forced against the mold by the air pressure differential created by pulling a vacuum between the sheet and the mold.

Pressure Thermoforming
Pressure thermoforming can achieve the high quality, detailed look of injection molding with much less expensive tools. By using air pressures up to 100 PSI in addition to vacuum, textures, undercuts and other intricate details can be produced. While not as economical as vacuum thermoforming, the enhanced design freedom and higher precision make the method a good choice for instrument covers or other high-end products in volumes that may not justify the costs of injection molding.

Press Thermoforming
Press thermoforming is a method that utilizes matched dies to produce complex parts with superior mechanical properties. Relatively inexpensive tools can be used to produce parts with thin ribs, embossed numbers or other details that are difficult or impossible using other methods. In addition, materials up to 1 ½” thick can be processed using this technique. Billow thermoforming is a technique that uses compressed air to produce “blown” parts such as domes or skylights in quantities from one to thousands. Tool costs are minimal, which makes it a very economical process when used appropriately.
