Discover the power of less with MPI

In a rapidly evolving automotive industry, flexibility wins. ArcelorMittal Multi Part Integration® maximises automotive manufacturers’ ability to adapt through the power of less: less parts, less process, less floor space, less time, less materials, less CO₂ and less assembly cost.   

Harness the strength of steel and the power of less.  

 

 

MPI uses ArcelorMittal's PHS and patented laser-welding technology to streamline manufacturing and reduce assembly complexity by maximising part integration. This modular solution can be applied across all powertrains and can be used to simplify the design and production of the battery pack, chassis, and body-in-white applications for e-mobility and micro-mobility.   

Each MPI module streamlines production, reduces assembly complexity, saves weight, and shortens lead times. These efficiencies have tangible financial benefits, with operational and capital expenditure savings.    

Developed in close collaboration with OEMs worldwide, MPI draws on ArcelorMittal’s global reach, track record of innovation, and breadth of experience within the industry. MPI delivers the flexibility today's automotive manufacturers need, as they develop futureproof strategies and rapidly adapt to grow their local and international footprint.  

 

Multi Part Integration® (MPI)

 

ArcelorMittal’s MPI concept has already been applied to several vehicle parts across projects in three key regions: North America, China, and Europe. The results of the studies show that for every part produced using the MPI concept, significant emission, cost, and process savings are generated. Engineering firms such as Bertrandt and Kuka have provided support in the calculation of these savings.  

 

Benefits

Based on 6 MPIs combined. If we add other MPIs, performance and savings are likely to increase.
