MATERIAL PURCHASING & PROCESS GUIDE
Specify the sheet, the formed geometry and the visible surface together. OUJI coordinates sheet metal fabrication through specialist partners; CNC machining experience in an alloy does not establish its sheet-forming route.
SPECIFICATION REFERENCE
Sheet thickness, condition, grain or surface direction, bend geometry and weld requirements can change the fabrication review. Supply flat and formed information where available and identify which document controls.
| Sheet family | Material input | Fabrication question | Surface / inspection input | Reference / next step |
|---|---|---|---|---|
| Aluminum sheet | Alloy, temper and thickness | Which bend radii and formed dimensions are required? Is welding included? | Show final dimensions after any anodizing or coating | Aluminum material context |
| Stainless sheet | Grade, thickness and supplied surface | Which faces are visible? Does grain direction need to be retained through forming? | Define brushed direction, weld appearance and any passivation | Stainless material context |
| Carbon steel sheet | Full sheet grade, thickness and coated / uncoated stock | Are welds, inserts or threaded features included in the assembly? | Specify corrosion protection, masking and final coating acceptance | Steel material context |
| Copper, brass or special sheet | Exact alloy, temper and product form | Does the part require forming as well as cutting or machining? | Mark contact faces and appearance requirements | Partner fabrication review |
A DXF can describe the cut outline while a formed model describes the assembled shape. Include bend details and final dimensions; identify whether the supplier may develop the flat pattern from the controlled formed drawing.
Call out weld scope, inserted hardware and any features that need machining after forming or assembly. These operations belong in the same quotation when they affect the delivered fit.
The fabrication and finishing scope is partner-coordinated. Refer to OUJI’s CNC capability pages for in-house milling or turning requirements instead of presenting all sheet operations as in-house processes.
DRAWING TO QUOTATION
Send the drawing and quantity. We’ll review the material, machining route, finish and inspection requirements together.
Response within 24 hours of receiving complete project details.
Details already in your drawing do not need to be repeated. If a material is undecided, tell us what the part needs to do.
