Precision and speed give a competitive edge in modern manufacturing
In modern manufacturing such as welding of chassis parts in automotive industry, surface treatment in tooling industry or cutting in solar cell industry, lasers have become essential. The contactless processing without transmission of force as well as the high accuracy and speed are only some of the features that make the use of a laser attractive to microtechnological applications. With suitable methods even structures in the nanometer range can be achieved. These methods include two-photon-absorption or interference lithography.
Our long-time experience in laser micromachining is the basis from which we elaborate individual solutions in the course of our cooperation with project partners. We offer to conduct technological feasibility studies, the realization of functional models as well as the fabrication of pilot series. If desired, we arrange a technology transfer or build up systems which are tailor-made to meet the requirements of our customers.
We use a range of lasers for the realization of most tiny structures as well as in microtechnological assembly and packaging technology.
