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.

With over 20 years of experience in injection mold design, I specialize in tooling for export markets, serving clients in Europe, North America, and Asia. I have deep expertise in complex mold structures, including 2-shot, unscrewing, water-assisted, rotary core, and multi-ejector molds. I am highly proficient in complete 3D mold design using Proe/Creo and UG, along with precise 2D machining drawing output via AutoCAD. My portfolio spans tier-1 automotive brands (Bentley, Mercedes-Benz, BMW, Audi, VW, Volvo, Land Rover, Toyota), home appliances (refrigerators, vacuum cleaners, lawnmowers), and medical devices (thermometers, blood pressure monitors, breast pumps). Recently, I have focused heavily on powertrain components like engine manifolds, covers, and pipe joints, as well as industrial locks, serving major clients such as SOFEGI and MAHLE. Currently operating as an independent freelancer, I partner directly with Western SMEs in the mold-making industry to provide high-quality, outsourced design services. I can handle the entire process from DFM analysis to complete tooling drawings, delivering: • Complete 3D mold design • DFM (Design for Manufacturability) reports • 2D machining drawings (AutoCAD) • Mold modification solutions and structural optimization If you are looking for a reliable partner who communicates directly, understands Western tooling standards, and delivers on time, let's connect.

Hi, I'm Marvin — a Plastic Injection Mold 3D Designer based in Dongguan, China, with 12 years of experience in EXPORT injection molds. For over a decade I've designed molds built to European and North American standards, and I work daily with HASCO, Meusburger, DME, Stack, and Knarr standard components. From 2019 to 2026 I worked as a Design Supervisor leading a small team — so I don't just draw, I take responsibility for whether the mold actually runs in production. What I deliver: • Complete 3D mold design (core, cavity, inserts, sliders, lifters, ejector, cooling, gating) — to HASCO / Meusburger / DME layouts • DFM review before you cut steel • Production-ready 3D drawings with 2D and BOM • Optional Moldflow / flow simulation Why work with me: • 12 years, export molds only — I know what overseas customers expect on drawings and in mold reports • Detail-obsessed: I check cooling balance, draft, shutoff, ejection, and machinability before you pay for steel • Based in Dongguan — I can refer you to trusted, vetted Chinese mold makers if you need someone to build the tooling • Honest: if your part will have molding problems, I'll tell you up front Send me your STEP / X_T files — I'll reply quickly and honestly. Best, Marvin
