Heat Bending and Cold Bending of Plastic

Bending Plastics

Bending plastic is a cost-effective method for shaping durable and precise components. It is often used to form complex shapes without compromising the material's strength.

This technique reduces the need for joints and fasteners, resulting in a stronger and more aesthetically pleasing solution.

The bending process can be performed either as cold bending or hot bending. The choice of method primarily depends on the material, the intended purpose, and the desired quality.

Heat Bending

of Plastics

Heat bending is our primary bending method.

In heat bending, the plastic sheet is heated over a glowing wire until it becomes soft. Once the plastic reaches the correct bending temperature, the component is bent manually. The piece is then held in place during cooling, allowing it to retain its shape.

This method is ideal for larger and more complex components that require precise and smooth bends. It enables sharp corners and clean lines, which are essential for technical applications.

When bending components in larger batches, we utilize our robot in the bending process to ensure the most efficient production.

Cold Bending
of Plastics

Cold bending can be done faster and more cost-effectively with smaller components than hot bending. Unfortunately, not many materials are suitable for this process, which is why we often recommend hot bending.

The cold bending of plastic sheets occurs similarly to the bending of metal; however, since plastic is more dynamic or "alive" than metal, it presents several challenges.

When cold bending, tension often develops in the bent area. This tension can cause the sheet to return to its original shape, either partially or completely. The absence of heat as a fixing agent makes it difficult to achieve a satisfactory and lasting result.

If you would like to receive a non-binding quote or place an order, simply send an email to induflex@induflex.dk.

Please attach a drawing of your item in STEP format, along with a PDF if possible.

You are also welcome to call us at +45 9837 1988 or fill out the contact form below, and we will ensure that the right employee contacts you.

We will send you a quote with a price before we start producing your order, unless we agree otherwise.
At Induflex, we can produce even very tight tolerances in plastic.

When you order a plastic component from us, it will meet the Danish Standard ISO 2768-1 (medium) as standard. We measure tolerances at room temperature, around 21 °C.

Of course, we can agree on a different tolerance if you wish.
