Kinematic HVAC Louver Assembly
Fiverr
Jul 2026 - Jul 2026 • 0 mos
The client provided a raw 3D scan of a vehicle interior and needed a modernized, manufacturable dashboard assembly. I reverse engineered the 3D mesh into flawless SolidWorks Class A surfaces, ensuring perfect OEM level panel gaps. Next, I engineered a functional HVAC air vent louver system in Fusion 360, designing precise linkages and snap fits to withstand cabin vibrations. Finally, I ran a strict DFM analysis, optimizing wall thicknesses and draft angles for mass production. I delivered tooling ready STEP files, enabling the client to injection mold the complete assembly on their very first attempt without any expensive factory rework.

Led mechanical design and DFM validation for complex automotive and consumer electronics injection molds. My core responsibility was transforming raw client CAD into tooling-ready core and cavity splits, ensuring 100% manufacturability. I spearheaded the use of advanced Moldflow simulations to artificially balance runners in multi-cavity family molds, eliminating flash and short shots in thin-wall components. Over six years, I engineered 150+ mass-production tools, directly reducing CNC tooling rework by 40% through rigorous draft analysis, shrinkage compensation, and Class-A surface validation in SolidWorks.
