Mechanical Design Engineer with 10+ years of experience in product mechanical design for consumer electronics, automotive switch modules, connectors, and precision mechanical components like plastic enclosures, sheet metal parts, and die-casting parts. Previously, I worked at global companies such as Amphenol and Littelfuse, where I was responsible for mechanical design, 3D modeling, assembly design, manufacturing drawings, and supporting products from development to mass production. I specialize in 3D product design, CAD drafting, DFM, and rapid prototyping. My experience covers the complete product development process, from concept design and engineering drawings to prototype validation and manufacturing support. My expertise includes: • 3D modeling and assembly design using Creo • 2D CAD manufacturing drawings and technical documentation • Product structure design for consumer electronics products/electronic components/precision mechanical parts • DFM for plastic injection parts, sheet metal structures, 3D printing • 3D printing design, prototype optimization, and design validation • Converting sketches, PDFs, or ideas into accurate CAD models • Supporting prototype builds and design optimization I can help with: • CAD drafting and technical drawings • 3D modeling for mechanical parts • Product structure design • Design optimization for manufacturing • STEP / DWG / STL file preparation • 3D printing design and prototype preparation I focus on accurate design, clear communication, and fast delivery. Feel free to contact me to discuss your project.

I'm a product mechanical engineer in robot, consumer, networking and medical device, I'm familiar with plastic product, sheet-metal product, CNC product and die-casting product design and these products manufacturing process. I also can provide engineering analysis, such as tolerance analysis, thermal design and analysis, finite element analysis(static/shock/random vibration/fatigue).I'm based in south of China, I can provide manufacturing support if you need.
