About Han Dong
Han Dong’s documented work spans product definition, mechanical design, DFM, injection molds, supplier coordination, mold trials, engineering changes, and manufacturing follow-through.
The career history and product examples below document prior professional work. They are not SourceBridge client projects and do not imply SourceBridge ownership, former-employer or customer endorsement, current employment, or certification in any particular export market.
Documented experience
2013–2018
Injection Mold Engineering
Responsibilities included product and manufacturability review, 3D injection mold design, manufacturing drawings, CNC and mold-assembly follow-up, and T0/T1 mold-trial issue resolution. Documented work includes a refrigerator air-duct cover and its injection mold.
2018–2023
Materials, CMF & Product Development
Documented work included in-mold decorative components, CMF and process development, PET refrigerator interior components, tooling and production-launch support, and mechanical development for the XCOOK food-storage product.
Work documented from 2024
DC Charging Connector & Cooling-System Development
Documented work included DC charging connectors and related cooling-system engineering, covering mechanical structure, thermal considerations, interfaces, and engineering-validation coordination. No current-employment claim is made.

Collaboration
Email the product, current stage, target deliverables, schedule, and the China-side support needed.
Confirm deliverables, manufacturing party, responsibilities, information access, schedule, and commercial terms before technical work begins.
Work to the agreed scope, keep actions and issues visible, and close with the required files, records, verification status, or next-step recommendation.
