Mold Design & Manufacturing
DFM review, injection mold design, supplier tooling coordination, mold trials, tooling modifications, and delivery follow-through.
From Engineering Design to Manufacturing Execution.
SourceBridge Engineering helps hardware teams worldwide develop physical products, engineer injection molds, coordinate plastic-part production, and manage technical execution with manufacturing partners in China.

Four focused services for product development and manufacturing execution.
Scope, responsibilities, schedule, deliverables, and manufacturing responsibility are defined before technical work begins.
Plastic Parts Production & Assembly
DFM, injection molding coordination, Color, Material & Finish (CMF) alignment, sample follow-up, and defined assembly support.
Hardware Product Development & Manufacturing
Mechanical design, prototyping coordination, supplier alignment, engineering change management, and manufacturing handoff within the agreed scope.
China-Side Technical Project Support
Supplier coordination, drawing and revision control, agreed factory-visit support, action tracking, issue resolution and verification, and written reporting.
Engineering experience behind the work
Han Dong
Product Development & Engineering Project Lead
Han works across product definition, mechanical design, DFM, tooling, supplier coordination, mold trials, engineering changes, and manufacturing follow-through. His documented prior experience includes appliance tooling, materials and CMF development, smart hardware, and EV charging products.
