Thermoforming creates many parts and materials that we see in our everyday lives. Such products that utilize thermoforming include disposable cups, containers, refrigerator liners, tanning beds, and vehicle interiors. Industrial ovens are used for heating the plastic in the thermoforming process. Thermoforming ovens heat sheets of plastic to a high temperature so they can be stretched and molded into a shape. Two methods of shaping the material after heating 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.
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 less.
Wisconsin Oven manufactures thermoforming ovens in both batch and conveyor configurations.
