ArcelorMittal’s Multi Part Integration™ (MPI) concept allows multiple vehicle components to be integrated into one large laser welded blank (LWB). MPI is one of the most cost-effective ways for carmakers to develop and deploy sustainable mobility solutions while simplifying vehicle design and production.
ArcelorMittal’s Multi Part Integration™ (MPI) concept allows multiple vehicle components to be integrated into one large laser welded blank (LWB). MPI is one of the most cost-effective ways for carmakers to develop and deploy sustainable mobility solutions while simplifying vehicle design and production.
ArcelorMittal Multi Part Integration™ uses the latest press hardenable steels (PHS) and laser welding technology to create a single part. The MPI part can replace several separate parts with one – reducing the weight and complexity of carmaking significantly.
The viability of the MPI concept has already been proven for various applications and production vehicles with MPI parts are already on the roads of Asia, Europe, and North America. ArcelorMittal Global R&D has also developed several case studies which show how MPI can be contribute to simplificiation today while offering OEMs significant reductions in costs, weight, emissions, and lower investments in tools and production space.
Further studies are in progress and will be as they are completed. ArcelorMittal is undertaking further studies and continue to develop the MPI concept in response to new challenges facing the automotive market.
The top 6 benefits of the MPI concept for OEMs :
Combining multiple parts into one greatly simplifies the part production process and associated costs. Advantages include:
Using MPI, one modular solution can be developed for multiple powertrains and vehicle types including e-mobility and micro-mobility solutions.
Part shape and the distribution of material is similar for every powertrain. Patches can be applied to the part to add reinforcement for a specific powertrain – without increasing costs.
MPI solutions can be used with almost any powertrain including:
OEMs already use laser welded blanks (LWBs) to ensure that the right steel, in the right thickness, is in the right place to enhance crash performance. LWBs have continuous weld lines which enhance energy absorption and the behaviour of the part during a crash. LWBs also eliminate weak points in the part.
MPI parts utilise ArcelorMittal’s latest press hardenable steels (PHS) to dramatically enhance safety while reducing mass.
ArcelorMittal PHS families – such as Usibor® and Ductibor® – are ideal material choices.
Working in combination these grades enable engineers to tailor how a part behaves in a range of crash scenarios.

By integrating multiple parts into one, OEMs can reduce the overall mass of the part. This approach offers many sustainability benefits including:
ArcelorMittal contracted an independent external partner to calculate the cost savings from every MPI study. The methodology uses an ideal, virtual plant which produces 150,000 vehicles annually. The calculation assumes that the same vehicle – in different powertrain versions – is produced for five years.
Each study contains more information on the potential cost reductions when MPI is deployed.
ArcelorMittal’s MPI concept has already been applied to several vehicle parts in detailed. The results of the studies show that for every part produced using the MPI concept, significant emission, cost, and process savings are generated.
The following MPI case studies are already complete:
