Overview
Manufacturing depends on controlled revisions. When a file changes, the quote, supplier match, lead time, material plan, and inspection scope may also change. Clear revision control helps prevent wrong parts and makes issue resolution faster.
Revision control
- Use clear file names such as part-name_rev-B.step and part-name_rev-B.pdf.
- Upload the model and drawing revision together when both change.
- Describe what changed if a quote is being updated.
- Do not assume a supplier will notice small geometry changes without a revision note.
- Once production starts, revisions may require stop-work, re-quote, or new lead time.
Change impact
| Change | Possible impact |
|---|---|
| Geometry update | Machine time, tooling, material, feasibility, supplier routing, and price may change. |
| Material change | Availability, finish compatibility, strength, and lead time may change. |
| Tolerance change | Inspection effort and supplier capability may change. |
| Finish change | Post-processing, masking, color, and schedule may change. |
| Quantity change | Setup amortization, unit price, and production plan may change. |
Issue reporting
- 1Document the issue
Take clear photos, measurements, order number, part number, and revision details.
- 2Compare against scope
Check model, drawing, tolerance, finish, and order notes.
- 3Contact support
Submit the issue with evidence so Uretyco can review supplier records and order requirements.
- 4Resolution path
Depending on findings, the path may be clarification, replacement, rework, return, credit, or updated production scope.
Returns and rework
Custom manufactured parts are usually produced to a specific order scope. Return or rework eligibility depends on whether the delivered parts conform to that scope, whether the issue is documented, and which terms apply to the order.
Preventing issues
- Use drawings for all critical requirements.
- Confirm units and revisions before checkout.
- Order prototypes before large batches when the design is new.
- Ask for inspection reports or sample approval when the risk justifies it.
- Define cosmetic requirements before finishing starts.
FAQ
- Can I revise a part after ordering? It may be possible, but production status determines cost and lead-time impact.
- What evidence helps issue review? Photos, measurements, drawings, order notes, and revision files.
- Are custom parts returnable? Return handling depends on order terms and whether the issue is a conformity problem.
