Plastic sheet material can be thermally processed by draping or thermal bending.
Draping or drape forming is usually done with a single curved surface, an arc. Sometimes it is possible to create a double-curved surface, depending on the radius and material.
The plastic plate is heated and then slowly laid over a curved mold. By controlled cooling it takes on the shape of the mold and after that finished into a customized product.
In thermal bending the elastic limit of plastics is explored, after which the material can be bent into the right angle. After cooling it will remain in the desired position and can then be finished into a customized product.
