DCI’s time-zone-opposed and tele-video linked Hong Kong and US offices co-manage production of top quality prototype parts and assemblies.


Design Circle’s U.S. model shop produces mock-ups, breadboard models, licensed sculpture, functional display models, RTV molds, urethane castings, and product samples. Running changes to all prototypes are made in our US facility reducing otherwise lost shipping time to China.

Design Polygon’s digitally driven facility in Shenzhen, China produces hand fabricated, SLA, RP, and CNC-machined precision appearance and functional electro-mechanical models; engineering check models, tooling patterns, and pre-production product samples.


Using our two facilities together, we produce the most rapid, and cost effective, professional prototypes available.
