The decrease of weight to improve fuel economy while increasing crashworthiness Crashworthiness is the ability of a structure to protect its occupants during an impact. This is commonly tested when investigating the safety of vehicles.

Depending on the nature of the impact and the vehicle involved, different criteria are used to determine the
 are demands among the top priorities of today's automotive OEMs. To combine those criteria, the use of High-Strength Steels (HSS HSS Humanities and Social Sciences

) and Aluminum is inevitable. However, in order to employ these complex metal structures intelligently, an in-depth understanding of the full vehicle as well as a comprehensive expertise in the areas of development, design and engineering, and die construction are required. Automotive OEMs and suppliers can find that capability at MBtech Group and MBtech Autodie. As a leading global engineering provider and die manufacturer, MBtech Group and MBtech Autodie offer turnkey "From Art-to-Part with High-Strength Steels (HSS), Advanced High-Strength Steels (AHSS) and Aluminum" services for diverse industries worldwide with immediate effect.

The combined expertise of MBtech Group in Class A Surfacing & Technical Design and Body Development together with the competence and experience of MBtech Autodie in Metal Forming (Die Design & Engineering, Machining, Construction, Functional Tryout, Launch Support, Die Repair), enables MBtech to take its customers from Art-to-Part with High-Strength Steels (HSS), Advanced High-Strength Steels (AHSS) and Aluminum meeting the highest quality requirements for complex sheet metal parts.

MBtech Group - MBtech Autodie excel in finding solutions to difficult metal forming problems by determining best material fits for specific applications, assessing formability (virtual and physical), accounting for geometrical limitations, coating and joining challenges, and resolving complex matters with spring back, splitting and wrinkling -- issues that are emphasized when dealing with High-strength steels (HSS), Advanced high- strength steels (AHSS) and Aluminum.

Together with Chrysler, American Iron and Steel Institute The American Iron and Steel Institute (AISI) is an association of North American steel producers. With its predecessor organizations, is one of the oldest trade associations in the United States, dating back to 1855. It assumed its present form in 1908, with Judge Elbert H.  (AISI AISI American Iron and Steel Institute

) and Mercedes Group Research, MBtech engineers worked on a Light Weight Body Project. This advanced engineering project developed and then applied a new design process which was CAE (1) (Computer-Aided Engineering) Software that analyzes designs which have been created in the computer or that have been created elsewhere and entered into the computer.  lead with a holistic approach, and successfully applied advanced optimization techniques to achieve the project goal of significant weight reduction of the body-in-white using Advanced High-Strength Steels on the optimized load paths.

Due to numerous projects including R&D, MBtech Autodie - MBtech Group's tool & die expert based in Grand Rapids, MI -- has many years of valuable knowledge and experience in building dies producing aluminum, HSS, and AHSS parts.
