Launched over 30 years ago as the first spin-off of the Fraunhofer Institute for Laser Technology (ILT) in Aachen, RJ Lasertechnik GmbH stands as a pioneer in industrial laser processing. Today, we deliver expert solutions across three core divisions: precision laser manufacturing, cleanroom process technology, and custom laser system construction.

We serve as a trusted partner for both mid-sized enterprises and international corporations, providing scalable laser welding, cutting, drilling, and marking services.

Our specialized expertise supports critical industries including semiconductor technology, medical device manufacturing, aerospace, laser optics, and precision mechanical engineering.

Our state-of-the-art manufacturing facility produces intricate cuts in steel, ceramics, and special alloys with a minimal heat-affected zone. Thanks to well-thought-out production planning and our in-house QCW fiber laser, we guarantee absolute on-time delivery and quality for your urgent needs, from prototypes to series production.

For sensitive components used in semiconductor and medical technology, we offer maximum particle purity in our own Class 8 cleanrooms. With fully automated systems developed in-house and strictly controlled conditions, we guarantee the highest quality standards for your critical components.

For over 30 years, when off-the-shelf solutions reach their limits, we have been developing custom high-performance systems tailored to your specific manufacturing tasks. From 3D design through CE-certified implementation to on-site commissioning, we offer complete, one-stop solutions that are perfectly tailored to your production processes.

As part of Andra Tech Group, we leverage 75+ years of experience across 11 companies and 13 manufacturing facilities in Europe and North America to deliver unified precision mechanical solutions. Our integrated ecosystem features specialized Competence Centers in Laser Technology, Additive Manufacturing, Cleaning & Qualification, and Plastic Components, serving critical sectors from semiconductors and aerospace to automotive and FMCG.

This synergy guarantees operational feasibility for any demand, combining expert production, logistics, and quality assurance to ensure timely delivery and micron-level precision—from complex prototypes to high-volume series; even under the most challenging conditions.

Consulting and process development

We specialize in comprehensive requirements analysis and qualified technical consulting across industrial laser services, ISO-class cleanroom manufacturing, and custom laser system construction. Our primary goal is to optimize existing processes or develop new manufacturing solutions that increase efficiency, enhance product quality, and minimize production costs for your specific application.
