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.

Senior Mechanical Design Engineer with 15+ years of hands-on industrial machinery design and manufacturing experience (BEng in Mechatronics Engineering from Soochow University). I specialize in 3D parametric CAD modeling (SolidWorks, Autodesk Inventor, Siemens NX), DFM-compliant shop drawings, dynamic mechanism design, and turnkey industrial automation integration. Core Technical Expertise: • Multi-CAD 3D Modeling: SolidWorks (Primary), Autodesk Inventor, and Siemens NX. Expertise in Part & Assembly families, Design Tables, Equations, Feature Suppression, and Top-Down Skeleton/Layout sketches. • Production Engineering Package: 2D manufacturing drawings adhering strictly to ASME Y14.5 GD&T standards, AWS welding symbols, bend deductions, and structured BOMs. • Shop-Floor Machining Experience: Direct background in 3-axis CNC milling and lathe machining. Every design is optimized for real-world manufacturability, tool clearances, and tolerance stack-up. • Equipment Focus: Non-standard automation machinery, Machine Vision & AOI inspection equipment, rotating equipment (drive shafts, roller systems, bearing blocks), structural frames, and custom jigs/fixtures. • C# Software & Automation Integration: Experienced in C# HMI upper-computer development, PLC control logic, and CAD API automation scripts. Whether you need a configurable 3D product family, design modifications, or production-ready job shop drawings, I deliver clean, error-free, and maintainable engineering deliverables.
