Faster Prototypes. Controlled Production.

OUJI combines a dedicated prototype engineering team with flexible multi-process equipment to move new parts from drawing review to machining faster, while repeat production remains separately controlled.
01

DEDICATED PROTOTYPE MANUFACTURING

Integrated Processes for Faster Prototypes

Our prototype specialists review every drawing and convert engineering requirements into a unified manufacturing standard, creating a clear and efficient route from design intent to finished part.

  • 10 conventional lathes provide flexible support for rapid turned-part development
  • EDM, manual precision milling and grinding work together in one prototype route
  • Standardized engineering conversion reduces handoff time and improves prototype efficiency

REPEAT TURNING PRODUCTION · 500+ PARTS

Dedicated Control for Repeat Turning

Orders of 500 turned parts or more do not run through the prototype workflow. They enter an independently managed production system with separate workshop planning, personnel, scheduling, process control and quality gates.

  • Prototype and repeat turning orders managed separately
  • Dedicated personnel, planning and production control
  • Locked setups, inspection gates and traceable output

APPLICATION-LED CNC TURNING

CNC Turning for Demanding Industries

OUJI supports precision turned components from prototype through controlled production. Each project is planned around stock condition, concentricity, thread requirements, inspection, repeatability and delivery.
