In response to the automotive industry's increasing demand for lighter, safer, and more sustainable vehicles, ArcelorMittal and TRUMPF have joined forces. This partnership combines ArcelorMittal’s expertise in advanced automotive steel with TRUMPF’s cutting-edge laser technology, enabling the precise shaping of laser-welded, hot-stamped ArcelorMittal Multi Part Integration® (MPI) parts for modern vehicle design.



TRUMPF’s 5-axis laser cutting machines integrate seamlessly with ArcelorMittal’s solutions to create efficient, sustainable production lines.

TRUMPF’s non-contact 3D laser cutting process ensures burr-free edges and minimal waste, while reducing production line wear. These innovations enhance the performance of ArcelorMittal Multi Part Integration® (MPI) solutions, which streamline vehicle design by combining multiple vehicle components into a single Laser Welded Blank (LWB).

Numerous MPI applications are available and can be tailored to customer requirements thanks to this state-of-the art technology – highlighting the “Power of Less”



Sustainability is at the core of this collaboration. By reducing material waste and optimising production processes, TRUMPF’s laser technology not only streamlines manufacturing, but also aligns with the industry’s growing demand for environmentally friendly practices. The non-contact nature of laser cutting ensures minimal wear on equipment, further enhancing the sustainability and efficiency of production lines.

“With TRUMPF’s laser cutting solutions, we’re pushing the boundaries of what’s possible in automotive manufacturing, and enabling MPI parts to simplify production and design."
Andreas MĂĽllegger, Business Development Manager for Car Body Applications, TRUMPF
"This partnership allows us to anticipate industry trends and deliver innovative solutions globally to meet future demand."
