Case Study: Commercial kitchen equipment manufacturing
Automated laser welding solution increases efficiency and quality
LASOtech designs laser welding cells with OTC handling robots
As a DAIHEN Smart Solutions Europe project, an automated laser welding system was implemented at RATIONAL GmbH to address skilled labor shortages and ensure consistently high-quality stainless-steel components. The solution enables efficient, precise, and scalable production for demanding commercial kitchen applications.
RATIONAL GmbH
Commercial kitchen equipment manufacturing
RATIONAL needed to automate welding and handling of thin stainless steel components to increase production throughput, ensure consistent high quality, and address skilled labor shortages – all while meeting strict hygiene and aesthetic standards.
A fully automated laser welding system featuring:
- OTC FD-V210 robots for material handling,
- OTC FD-V166 robots integrated with laser welding optics,
- Four laser welding cells supplied by eight material stations,
- A central PLC control for synchronized processing,
- RMU (Robot Monitoring Unit) for safe, repeatable robot positioning.
This setup enables precise, oxidation-free welding of thin stainless steel without deformation, suitable for various cooking chamber sizes and models.
-
Automated production running three shifts with only one operator.
-
Consistent, high-precision laser welds that meet ISO-level quality and hygiene requirements.
-
Increased production flexibility allowing varied lot sizes and configurations.
