Multi Part Integration at 2021 Aachen Body Engineering Day

 

ArcelorMittal’s MPI concept will be presented during the 14th Aachen Body Engineering Day to be held on 21 and 22 September 2021.

 

The transition to electrification is creating many challenges for the global automotive industry. One of the most complex is how OEMs manage the need to produce vehicles with different powertrains (ICE, MHEV, PHEV, and BEV) at the same time.

Multiple assembly lines

ArcelorMittal Global R&D and ArcelorMittal Tailored Blanks have developed an innovative approach to reduce that complexity by integrating many parts into just one laser welded blank (LWB). Known as Multi Part Integration (MPI), the solution uses ArcelorMittal’s latest press hardenable steels (PHS) and hot stamping technology to create the single part.

ArcelorMittal’s first MPI concept has reduced the rear H-frame of a PHEV from 11 separate parts to just one LWB

The MPI door ring reduces the number of spot welds from 310 to just 66 per vehicle

For OEMS, the benefits include:

  • Radical simplification of the vehicle production process, including a reduction in the area required
  • One common and modular solution for multiple powertrains
  • Enhanced crash management
  • Considerable sustainability (CO2) gains including a lighter finished vehicle
  • Potential cost savings of up to 10 percent.

 

The speakers will include Jessé Paegle, Head of Product & Solution Development at ArcelorMittal Tailored Blanks, and Dr.-Ing. Joël Wilsius, a research engineer for steel automotive applications at ArcelorMittal Global R&D.
