I help companies turn product ideas into functional, manufacturable designs — from concept development and 3D CAD modeling to prototype-ready solutions. With 20 years of experience in product development and manufacturing environments in China, I bring practical engineering knowledge from injection molding, tooling, and production processes into every project. My strength is not only creating CAD models, but understanding how products will actually be manufactured, assembled, and improved before moving into production. My professional background includes: • 7+ years in injection mold design and tooling development • 5+ years in plastic product design and mechanical engineering • 6 years managing engineering projects and localization programs • Experience working with international customers, suppliers, and manufacturing teams My services include: ◆ Plastic Product Development - Concept development and mechanical design - 3D CAD modeling (Siemens NX) - Product structure optimization - Prototype-ready design - Design improvement based on function, assembly, and manufacturability ◆ Design for Manufacturing (DFM) - Plastic part design review - Wall thickness, rib, boss, snap-fit optimization - Draft angle and molding considerations - Material and process recommendations - Risk identification before tooling ◆ Manufacturing Cost & Production Optimization - Manufacturing cost driver analysis - Design optimization for cost reduction - Tooling cost evaluation - Mold configuration recommendations - Material selection for cost and performance - Production feasibility assessment - Supplier quotation review - Manufacturing process optimization ◆ Injection Molding & Manufacturing Support - Mold feasibility review - Tooling risk assessment - Technical communication with manufacturers - Prototype and engineering change support I have worked on projects including industrial components, plastic products, and consumer products where practical engineering decisions are critical. If you need an engineering partner who can improve manufacturability, reduce production risk, and optimize manufacturing cost before tooling, I'd be happy to discuss your project.

I am a mechanical design engineer focused on turning product ideas into practical, manufacturable designs. I help with mechanical concepts, 3D CAD modeling, assemblies, technical drawings, electronic enclosures, and prototype-ready design packages. My main interests are robotics, compact smart devices, and electromechanical products. I can support requirement clarification, enclosure and internal layout, mechanism design, component integration, design reviews, and preparation for 3D printing or manufacturing. What you can expect: • Clear milestones and documented assumptions • Careful attention to fit, assembly, serviceability, and manufacturability • STEP/STL and drawing handoff suited to the agreed scope • Responsive communication and structured revisions I prefer well-defined, milestone-based projects and will flag missing dimensions or technical risks before finalizing a design.
