About
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

Design Supervisor / Lead Mold Designer
An Export Mold Factory, Dongguan · Full-time
Jun 2026 –
Oct 2026
4 mos
Dongguan, China
Led a team of mold designers delivering export-quality injection molds to clients in Europe, North America, and Japan.
Responsible for full mold design packages: layout, core/cavity, sliders/lifters, gating, cooling, ejector, and 2D drawings.
Deep working knowledge of international mold standards: HASCO, Meusburger, DME, Stack, Knarr — designing directly to these standard component catalogs.
Performed DFM reviews with overseas customers and handled design changes through T0 / T1 / T2 sampling.
Personally reviewed every drawing before release to the toolroom. Focused on the small details that decide mold life: cooling balance, draft angle, parting-line shutoff, ejection angle, and machining-friendly geometry. -
Injection Mold Designer
An Export Mold Factory, Dongguan · Full-time
Jun 2014 –
May 2019
4 yrs 11 mos
Dongguan, China
Started my career in export mold design right after graduation, taking on small to medium single- and multi-cavity molds.
Built 3D models and 2D drawings directly to HASCO / DME standard layouts for overseas customers.
Supported tooling trials and worked closely with CNC, EDM, and bench workers to resolve first-article issues.
Grew from junior designer to independently owning projects — from customer DFM discussion through mold acceptance.
