About ProByLas
ProByLas AG specializes in laser technology for welding plastics. The company offers both turnkey ready-to-run systems (Turnkey S and Turnkey M) and components for integration (Modula), consisting of laser, optics, clamping units and motion modules. In addition to system supply, the portfolio includes services such as design consulting, an application laboratory, commissioning, maintenance, troubleshooting and upgrades. The laser welding technology operates with contour-based, quasi-simultaneous, simultaneous and mask processes and is characterized by locally limited energy input, particle-free joints without scorch, and vibration-free joining of sensitive components. The systems are used, among other things, in medical technology, the automotive industry, electronics, consumer goods, textiles and the packaging industry. ProByLas serves customers in German and English and maintains contact offices in Switzerland and the USA.
