VLOG #4 - Multi Parts Integration - Double Door Ring


In this fourth episode of a series of videos about breakthrough applications of laser welded blanks, Jessé Paegle, Head of Product & Solution Development at ArcelorMittal Tailored Blanks, shows how the Multi Part Integration (MPI) concept applies to the Double Door Ring, the biggest part of a car structure. MPI radically simplifies the vehicle production process by reducing the number of operations, leading to significant sustainability gains and potential cost savings.


What is Multi Part Integration?

Multi Part Integration (MPI) is a new concept from ArcelorMittal Tailored Blanks which is designed to incorporate many parts into one laser welded blank (LWB). MPI uses press hardenable steels (PHS) and hot stamping LWB technology to create the single part. The goal is to simplify production for OEMs.

What are the benefits of Multi Part Integration?

The MPI concept brings significant benefits for OEMs including:

  • Radical simplification of the vehicle production process
  • One common and modular solution for multiple powertrains
  • Enhanced crash management
  • Considerable sustainability gains including a lighter finished vehicle
  • Potential cost savings of up to ten percent
