Bending of plastic

Plastic sheets can be bent by either heating or cold bending. Which method is used depends on the material and the desired quality
Bending of plastic sheets can be used for technical parts, such as slides and shields, and promotional items like sale displays and showcases.

Heat bending plastic

When heat bending plastic, sheets are heated until they becomes soft. The sheets can then be bended and is maintained in position during cooling. The plastic will then keep the shape. Heat bended plastic is not in anyway damaged, and the strength is as great as if the material was cast in the same shape.

In principle, all types of thermoplastics can be heat bended, but some types are more suitable than others. Eg it is difficult to keep the temperature right when bending PEHD 1000

Cold bending of plastic

Cold bending of plastic sheets is done in the same way as with metal, but plastic is more difficult to handle and there is the risk that tensions will make the sheet partially bounce back. But cold bending can be done faster and cheaper than heat bending. Furthermore, it is possible to cold bend different types of polyester.
Typical materials which are cold bended are PEHD and PC. Acrylic can not be cold bent.
