About
I am an automotive interior design engineer with 7+ years of experience in plastic part and injection mold design for Japanese OEM and Tier-1 suppliers.
I specialize in end-to-end product development, from concept design to mass production, ensuring manufacturability, cost optimization, and high-quality standards.
My expertise includes CATIA V5/V6, plastic structure design, and mold feasibility analysis. I have worked on interior components such as door trims, console parts, and small functional plastic assemblies.
I can support clients with:
3D modeling & 2D drawings
Rigidity/strength analysis
Mold design
Design modification for mass production
I am committed to delivering accurate, practical, and production-ready designs.
