Gustav Scharnau GmbH, Germany
Expertise with a zero-defect strategy
Gustav Scharnau GmbH places great emphasis on innovation and continuous development in its work with industrial adhesive tapes. Adhesive technology is constantly evolving and must respond to market requirements. To this end, the company focuses on maximum process reliability to optimise quality, in order to offer its customers the best possible results. Process expertise is firmly embedded in the company’s philosophy. As a result, the company is already making extensive use of digital processes and new opportunities today to continue meeting all future challenges.
Precision without adhesion
Advantages of laser cutting adhesive tapes
At Gustav Scharnau, semi-finished products made from adhesive tapes are manufactured, among other things, which are then used, for example, in the automotive industry to bond individual components. The advantages of laser processing adhesive tapes include consistently perfect cutting results and high repeat accuracy. In addition, a wide variety of contours can be cut, including tight radii or intricate details that are hardly achievable with other cutting tools.
The greatest advantage, however, is the clean cut edge. When cutting with knives, they quickly become blunt, and adhesive residues and material particles adhere to them, resulting in high cleaning and maintenance requirements. The laser avoids these problems through contactless cutting without contamination or adhesion.
High-performance laser systems for adhesive tapes
The systems used by Gustav Scharnau
Gustav Scharnau GmbH has an extensive machinery park, which has also been equipped with eurolaser systems since 1998. This includes five machines from the eurolaser M series, including M-1200 and M-1600 cutting systems. The high-performance laser systems are used for processing and cutting industrial adhesive solutions as well as adhesive tapes. Thanks to contactless cutting, clean cut edges are produced and no adhesive residues remain on the tool.
Laser cutting enables extremely short set-up times, generates no tooling costs, maintains the tightest tolerances and thus achieves productivity increases that are almost unimaginable. We have known eurolaser since 1998. In fact, we were the ones who originally gave eurolaser the idea of developing laser technology to cut our adhesive tapes. I would say it has paid off. High-quality laser-cut products are economical even for small batch sizes, for example in prototyping. In addition, we can quickly cut very large, complex and delicate adhesive tapes. We are talking about dimensions well beyond 700 millimetres. This is where our rotary die-cutting processes quickly reach their limits. We currently operate five eurolaser systems. The latest machine, which we affectionately call “the baby”, was only commissioned in 2020, and we are very satisfied with eurolaser.
