The twin sheet forming process

The twin sheet thermoforming process at Linbrunner involves clamping two sheets of plastic into a carriage and heating them on both sides. At the end of the heating process the moulds are raised and a vacuum is used to move the two homogeneously heated plastic sheets against the top and bottom mould. At the same time the two moulds move together to join the sheets at specific points. Compressed air is used to support the demoulding process.

Linbrunner’s twin sheet forming process is an environmentally friendly way of producing hollow parts, with the added option of integrating other parts, up to a maximum size of 2160 mm x 1260 mm.
Thermoformed parts manufactured in this manner are notable for their outstanding shock absorption characteristics and high stability, even when relatively thin materials are used. The twin sheet process can be used for the manufacture of complex shapes, different surface types and individual colour combinations. It is also possible to add screw-on components or other elements to the thermoformed parts.

Whether we create a one-off bespoke part or perform a full batch production run for you, here at Linbrunner, we bring a wealth of experience and real passion to each and every one of your products. We are relentless in our goal to make sure you are completely satisfied.
