Critical features
Identify functional datums, mating fits and relationships. Give these an acceptance method rather than imposing an undefined “tight tolerance” across every surface.
PARTNER-SUPPORTED MANUFACTURING / PRODUCTION
Production machining. Make repeatability a defined requirement.
Move from an approved part to a controlled production proposal. KeepWin helps align revision, material, process route, acceptance and delivery identity so repeat orders are based on a clear configuration.
Production route, lot scope, capacity, inspection, records, MOQ and schedule require project confirmation. A successful sample does not establish unrestricted volume or identical performance for every future lot.
Generated machined-part reference. It is not evidence of an actual production lot, customer project or factory capability.

01 / RELEASE BASIS
An approved sample needs an identified production basis.
A sample can answer a limited question. Before releasing a run, define the configuration and evidence it represents and any differences from the proposed production route.
| Item | Freeze | Resolve before approval |
|---|---|---|
| Design | Controlled model and drawing revision. | Conflicts, changed geometry and open functional questions. |
| Material | Grade or formulation, condition and allowed alternatives. | Required documentation and substitution authority. |
| Finish | Treatment scope and final-state requirements. | Masking, appearance references and dimensional effects. |
| Sample | Identity, checks and accepted features. | Whether it represents the offered process and final configuration. |
| Delivery | Part number, quantity, packing and required records. | Lot identity, destination and discrepancy handling. |
02 / ROUTE CONTROL
Define repeatability around the features that matter.
Material supply, holding strategy, setups, secondary operations and finishing can influence the final result. The proposal should identify responsible operations without implying a universal in-house route.
Supplied machining-setup reference. Responsible sites, equipment suitability and actual production route are confirmed for this project.
Material and condition
Control grade, supplied condition and any required treatment. Agree what material evidence and lot identity accompany the offered supply route.
Setup and secondary steps
Review how locating and clamping preserve important relationships. Identify rework, finishing or assembly operations that affect acceptance.
Changes and substitutions
Name who approves an altered material, operation, finish or component. State which changes require renewed samples, reports or quotation.
03 / PILOT SCOPE
Use a pilot or first article to close a named uncertainty.
Where an initial production check is needed, agree its purpose and how the decision affects the remainder of the order. It is not automatically included with every project.
Geometry and assembly
Evaluate the final-state features that establish fit and function. Explain whether a mating reference or assembly check is required.
Appearance and finish
Compare agreed visible areas, texture and color. Record what reference and conditions define acceptance across the run.
Records and handoff
Confirm the report, material evidence, identifiers and packaging that will be used for the production delivery.
04 / LOT ACCEPTANCE
Inspection scope must be explicit and practical.
A drawing, measurement report and inspection plan answer different questions. Agree critical features, methods, sampling and records against the intended function.
| Area | Decision | Record to request if required |
|---|---|---|
| Dimensions | Datums, critical features and measurement conditions. | Agreed dimensional or first-article report. |
| Sampling | Which features and quantities are checked. | Agreed sampling basis and lot identification. |
| Appearance | Visible surfaces, defects and physical reference. | Appearance approval and any requested inspection evidence. |
| Material / treatment | Grade, condition and documentation needs. | Available records with the agreed traceability scope. |
No default blanket inspection claim
Do not infer all-piece inspection, a capability study or a certification from the service name. Request the actual scope and confirm feasibility.
Final-state acceptance
Specify whether features are evaluated after finishing, heat treatment or assembly. Agree how nonconforming results and proposed rework are reviewed.
05 / DELIVERY & REPEAT
Preserve identity across cartons and reorders.
A repeat order is easier to review when the approved specification, quantity and required evidence remain connected to the delivered part.
Supplied material-stock reference. It does not demonstrate stock availability, batch traceability or production capacity.
- Reference the release
Part number, revision, approved sample and material scope.
- State quantities
Current lot, any staged deliveries and expected repeat pattern.
- Confirm the proposal
Route, acceptance, records, packaging and schedule assumptions.
- Identify the delivery
Variant, lot or other agreed identifiers and packing contents.
- Review the next order
Record changed requirements and confirm whether earlier approvals remain applicable.
06 / QUOTE FACTORS
Compare total scope, not only unit price.
A production quotation should make setup, samples, finishing, inspection, documentation, packaging and transport visible where relevant.
Part and quantity
Send the controlled files, grade, condition, sample quantity and production quantity. Separate variants and any staged delivery requirement.
Evidence and appearance
Specify critical dimensions, final-state finish, required records and approval checks. Explain any special traceability or packaging need.
Commercial assumptions
Ask what is included and which milestone starts the schedule. Identify tooling or setup terms and the process for changed quantities or specifications.
07 / QUESTIONS
Before releasing a machining run.
Keep the production commitment tied to an approved configuration and the actual proposed route.
Does one good sample prove every future lot?
No. Define what the sample represents and the production controls, acceptance and change review needed for future lots.
Can a production order start from a rendering?
A rendering can communicate intent, but controlled geometry, material, finish and acceptance requirements are needed before a production basis is approved.
Is every part measured automatically?
No blanket inspection scope is implied. Agree features, methods, quantities, sampling and records in the proposal.
Can material or finish be changed on a reorder?
The change needs review and approval. Confirm whether samples, inspection records, appearance or quotation assumptions must be revised.
What MOQ or capacity can be confirmed?
These are project-specific proposal items. State quantities, variants, repeat pattern and timing for the responsible supply route to review.
PREPARE THE NEXT DECISION
Bring the approved part and the production assumptions.
Share CAD and drawing revision, sample record, quantities, material and finish, critical features, required records and expected repeat-order pattern.
