DRAWING-BASED ROUTE REVIEW
From Drawings to a Practical Manufacturing Route
Before production starts, OUJI reviews drawings, material, tolerance, quantity, surface finish, and delivery target. This helps customers choose a practical manufacturing route before quotation.
Review drawing requirements
We check material notes, key dimensions, tolerance areas, threads, surface finish, heat treatment, and possible machining risks.
Select a suitable process route
Parts can be matched to CNC machining, sheet metal fabrication, 3D printing, surface finishing, or a combined manufacturing route.
Coordinate production follow-up
For multi-process projects, OUJI helps follow up production status, secondary processes, inspection, packing, and shipment preparation.
QUALITY & INSPECTION SUPPORT
Quality Follow-Up Based on Drawings and Project Requirements
For custom precision parts, quality control should start from drawing review. OUJI focuses on critical dimensions, appearance, surface finish, packing, and inspection documentation when required.
Critical dimension review
Important tolerance areas, thread features, datum references, mating surfaces, and functional dimensions can be highlighted before production.
Process and production follow-up
OUJI helps follow machining progress, secondary processes, surface treatment, inspection status, and potential delivery risks for selected projects.
Inspection documentation
Inspection photos, dimensional checks, material certificates, surface treatment records, and reports can be arranged based on project needs.
Packing and shipment check
We pay attention to part protection, surface separation, labeling, packing strength, and export shipment preparation before delivery.
PROJECT TYPES
Custom Manufacturing Support for Different Project Needs
Whether you are developing prototypes, preparing small production batches, or sourcing mixed custom parts from overseas, OUJI can help review the route and coordinate production based on your drawing package.
Prototype Parts
For fit checks, testing, appearance review, engineering validation, and design improvement before production.
Low-Volume Production
For small batches, pilot runs, repeat orders, spare parts, and overseas buyers who need practical follow-up.
Tight-Tolerance Parts

Yes. You can send 2D drawings, 3D files, material, quantity, surface finish, tolerance notes, and delivery target. OUJI can help review whether CNC machining, sheet metal fabrication, 3D printing, or a combined manufacturing route is more suitable for your project.
Can OUJI support tight tolerance parts?
Yes. Selected critical features can be supported down to ±0.005 mm depending on geometry, material, process route, inspection method, and supplier capability. Final tolerance should always be confirmed based on the drawing, function, and inspection requirements.
Do you support prototypes and low-volume production?
Yes. OUJI supports prototype parts, small batches, pilot production, repeat low-volume orders, replacement parts, and overseas OEM sourcing projects. This is one of the key manufacturing capabilities for buyers who need flexible production instead of large MOQ manufacturing.
Can you arrange surface finishing and secondary processes?
Yes. Depending on the project, OUJI can coordinate deburring, polishing, anodizing, plating, passivation, heat treatment, painting, powder coating, cleaning, inspection, labeling, and export packing.
What materials can OUJI work with?
OUJI can support common engineering materials such as aluminum, stainless steel, carbon steel, brass, copper, plastics, and selected engineering alloys. Material availability, machining risk, surface finish, and lead time should be confirmed according to the drawing and quantity.
Can you provide inspection reports with the parts?
Yes. Depending on project requirements, OUJI can support dimensional inspection, CMM inspection, appearance checks, material certificates, surface finish checks, and final inspection reports. Inspection scope should be confirmed before production.
