Thermoforming

Thermoforming involves heating sheets of plastic to soften them and allow them to be stretched, molded, and trimmed as required. The material hardens in the desired shape when cooled. Two methods of shaping the material after heating are vacuum forming and pressure forming. Thermoformed plastics are commonly used for the automotive, consumer products, packaging, and industrial applications. Plastics that are thermoformed include ABS, acrylic, CAB (cellulose acetate butyrate), EVA (ethylene vinyl acetate), PVC, high impact polystyrene, polycarbonate, and more. Thermoforming is a good alternative to injection molding for lower quantities, since tooling costs are lower. Wisconsin Oven offers a wide range of batch and conveyor ovens for thermoforming.
