Thermoforming is used to create many parts and materials that we see in our everyday lives. Plastics that are thermoformed are commonly used in automotive, consumer products, packaging, and industrial applications. Thermoformed products include disposable cups, containers, refrigerator liners, tanning beds, and vehicle interiors. Industrial thermoforming ovens are used for heating sheets of plastic to a high temperature so they can be stretched and molded into a shape. Two methods of shaping the material are vacuum forming and pressure forming. After the plastic has cooled and molded, the excess plastic is cut and the product can then move on to its next operation.
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 less. Wisconsin Oven manufactures thermoforming ovens in both batch and conveyor configurations.
