2. About Detroit Engineered Products (DEP)
• Incorporated in the state of Michigan in 1994
DEP is a full service Engineering Services & Software development
company with Innovative game changing technology that transforms the
product development process

3. DEP’s Meshwork’s
CAE & CAD Morpher is part of the Meshwork's Suite developed by
DEP has the capability of morphing CAE & CAD data in a wide
variety of scenarios very simply , efficiently and Rapidly.
Morpher can significantly reduce the initial
CAD data generation and concept
Engineering time since the data for CAD
Morpher is feed from available Performance
models and existing CAD Data.
Meshworks is Maintaining a leading edge
in Morpher enabled Design and
Simulation technology for the past
15years by continuously inventing and
innovating the tool capability to meet
industry needs and future technology
trends

15. DEP sample weight reduction success projects
1.China / Korea Small car program
35Kg. was successfully reduced from the BIW while meeting Crash, NVH, Aerodrag, Vehicle Dynamics and
Powertrain mounting targets. Executed for Chinese OEM whose development center is in Korea.
2.High Volume North American V6 Engine Optimization
3.High Volume North American LCV / MCV program
•Weight reduction on current large volume Cross-over platform
•Optimization reduce about 25 to 35Kg in BIW.
4.Multi-Powertrain Body structure Development for a US Global Midsize car program
•New architecture for Electric, Hybrid-electric and Conventional powertrain program
•85Kg. was reduced from the BIW while providing a common platform for three different powertrain configurations
5.Load Body Value Engineering
•~12Kg was reduced from a 102Kg. pick-up box.
• The value engineered load body was proven to have equivalent
• Design, prototyping and volume production carried out.
• Executed with minimal impact to current production tooling
