Custom Manufacturing Solutions
Custom Manufacturing Support for Prototype, Low-Volume and Complex Precision Parts
OUJI helps overseas buyers review drawings, choose practical manufacturing routes, and source CNC machined parts, sheet metal parts, finishing, inspection, and small-batch custom production.
Send your 2D drawings, 3D files, material, quantity, tolerance notes, and surface finish requirements. We aim to review standard custom part projects within 12 hours.

What Type of Custom Part Project Are You Working On?
Start with your project situation. OUJI helps review the right manufacturing path based on drawings, quantity, process complexity, tolerance needs, and delivery expectations.
Prototype Support
I need prototype parts before design freeze
For samples, fit checks, functional testing, fixtures, housings, brackets, and early-stage design validation.
Low-Volume Support
I need low-volume production without high MOQ pressure
For pilot runs, bridge production, repeat small batches, and flexible overseas sourcing.
Process Coordination
I need machining, finishing, heat treatment, or inspection coordinated
For CNC parts requiring anodizing, plating, deburring, grinding, EDM, heat treatment, or inspection reports.
Critical Feature Support
I need closer control for tolerance-sensitive features
For key holes, mating surfaces, flatness, concentricity, threaded features, and drawing-controlled dimensions.
Not Sure Which Solution Fits?
Just Send the Drawing. We Help Review the Manufacturing Route.
Many buyers are not sure whether a part should be CNC machined, sheet metal fabricated, finished first, heat treated later, or inspected with special attention. OUJI helps review the drawing and identify the practical process route before production starts.
Send drawings and requirements
2D drawing, 3D file, material, quantity, finish, tolerance, and inspection needs.
We review risks and process path
Machining method, secondary process, finish risk, tolerance concern, and delivery direction.
We reply with quote direction
Manufacturing route, lead time expectation, cost drivers, and next questions if needed.
OUJI Solution Areas
Four Practical Ways We Support Custom Part Projects
These solution areas are designed for overseas buyers who need more than a simple unit price. They need practical review, production coordination, and follow-up.

Quality-Critical Support
Tight-Tolerance & Critical Parts
For tolerance-sensitive features, critical assembly areas, key holes, flatness, concentricity, and inspection-controlled dimensions.
- Critical feature review
- Inspection planning support
- Quality-sensitive project follow-up
Why Buyers Use OUJI
Custom Part Problems Often Come From Poor Coordination, Not Machining Alone
For prototype and low-volume custom parts, delays and quality issues often happen when drawing risks, finishing requirements, tolerance expectations, and inspection needs are not reviewed early.
Drawing risks reviewed earlier
We check material, tolerance notes, surface finish, threads, and special requirements before production moves too far.
Finishing planned earlier
Anodizing, plating, heat treatment, and deburring can affect dimensions, appearance, cost, and lead time.
Inspection expectations clarified
Critical dimensions, fit surfaces, appearance areas, and report requirements should be clear before production starts.
Multi-process handoff controlled
OUJI helps coordinate machining, outside processes, inspection, packaging, and communication for custom projects.
Project Flow
How Your Custom Part Project Moves Forward
From drawing review to manufacturing route planning, OUJI helps keep project requirements clearer before production starts.
Drawing Review
We review drawings, material, quantity, tolerance, finish, and inspection requirements.
Manufacturing Route
We suggest the practical route based on CNC, sheet metal, finishing, heat treatment, or inspection needs.
Quote & Lead Time
We provide quote direction, lead time expectation, and key cost or risk factors.
Production Follow-Up
We coordinate production, outside processes, inspection, packaging, and delivery communication.
