Drawing-led engineering review
Material, tolerance, finish and critical features are checked before the manufacturing route is confirmed.
CUSTOM PRECISION COMPONENTS
Non-Standard Precision Parts Made From Your Drawings
When a component does not fit a standard catalog or a single industry, OUJI builds the manufacturing route around its geometry, tolerance, material, finish and inspection requirements.

WHY OUJI
Built Around the Drawing, Not a Standard Part
This service is for drawing-based parts that need a practical process decision rather than a catalog selection.
One coordinated process route
CNC machining, sheet metal, 3D printing, finishing and inspection can be coordinated around one project.
Critical features checked
Important datums, fits and dimensions become agreed inspection points before parts are released.
From one part to repeat orders
OUJI supports one-off prototypes, low-volume batches and controlled repeat production from the same drawings.
TYPICAL PARTS
Precision Components We Commonly Support
The part may be simple or complex; the common requirement is that it must be manufactured and checked against a clear drawing.Precision housings
Cavities, sealing faces, bearing seats and threaded interfaces.
Manifolds and blocks
Cross holes, ports, plugs and controlled internal passages.
Shafts and sleeves
Diameters, runout, grooves, threads and mating fits.
Brackets and structural parts
Custom geometry for equipment, instruments and assemblies.
Inserts and miniature parts
Small turned and milled components with burr-control needs.
Multi-process components
Parts requiring machining, EDM, grinding, heat treatment or finish.
MANUFACTURING ROUTES
Use the Process That Fits the Part
OUJI selects a route based on part geometry and risk, then coordinates the required operations and checks.
