The laser cuts even mounted foil on a table concept especially developed for this purpose. For foil machining, laser systems are provided with a special table concept, the honeycomb. The beeswaxlike structure, from a thin aluminum foil, is very stable and allows a particularly good vacuum to form under the material.
- Force-free effect due to contact-free cut
- Exact dimensional accuracy, without wear
- Without changing tools
- Filigree contours up to 1/10 mm
- Foil cables can be bridged
The most important consideration when processing the individual layers is precision and matching the life-spans of the different materials. Above all, the production of the membrane switch should be economical. On the other hand, the products must display very specific properties and fulfill special functions.
A few functional examples of complex foil assembly:
Using camera recognition registration marks can be accurately read by the laser system and the position of the foil layers to be processed can be determined with precision. The intelligent analysis of the register marks also makes a compensation of the dimensions possible. This serves to optimize or align to the necessary dimensional accuracy.
As a composite, most membrane switches can be e.g. contoured outwards, also after assembly.
