Geometry model
Useful for defined shape, space or assembly questions. Record material and route differences and avoid extending the result to molding-specific appearance or properties.
PARTNER-SUPPORTED MANUFACTURING / SAMPLE DECISIONS
Molding prototypes. Decide what this sample is allowed to approve.
A shape model, a resin sample and a molded prototype can answer different questions. Name the purpose and represented conditions so the approval supports the next decision without hiding unresolved production requirements.
KeepWin coordinates partner-supported review. Exact material, responsible operations, process availability, dimensions, inspection, commercial quantities and timing are confirmed in the project proposal; no universal capability or certification is promised.
Generated enclosure design study, not a sampled production part, measured inspection result or verified molding facility.

RecordAcceptance and transfer limits
01 / SAMPLE CHOICE
Choose a sample route that answers the question.
A printed shape and an actual molded component should not be treated as equivalent evidence. Compare what each represents before procurement.
Molded sample
Review the actual resin, tool and processing it represents. Define which fit, surface or functional checks support the next decision.
Initial production sample
Agree whether the offered sample represents the intended repeat configuration. Identify tool, cavity and processing questions still needing resolution.
02 / REPRESENTATION
Keep the sample condition in the acceptance record.
The value of a prototype depends on its relationship to the intended part and route. Write that relationship down before evaluating it.
Controlled files
State model, drawing, units and revision. Record sample-only changes, added reliefs or altered interfaces and their effect on the decision.
Material and processing
Name exact resin and the relevant completed state. A visually similar sample or family label is not automatically representative.
Tooling scope
Ask what tool and cavity configuration the sample uses. Confirm which characteristics transfer to the proposed repeat route and which require further review.
Mating and use references
Provide assembly parts, appearance references or functional conditions. Agree methods and the sample quantities needed for the actual question.
03 / EVIDENCE COMPARISON
Separate what is demonstrated from what is inferred.
Each approval should name the actual check and its limits. A successful sample decision does not settle every later manufacturing assumption.
| Sample decision | Evidence | Does not automatically prove |
|---|---|---|
| Shape | Controlled geometry and stated review. | Production material or tooling behavior. |
| Fit | Mating reference and checked interfaces. | Every dimension or service duty. |
| Appearance | Processed physical sample and viewing basis. | All colors, cavities or future changes. |
| Application | Defined method and material condition. | Uses or environments outside the evaluation. |
04 / TOOL & ITERATION
Define who approves the next revision.
Prototype work can create tool and geometry changes. Keep the decision owner, cost scope and resampling rules visible.
Open issues
List unresolved design, material, tooling or acceptance questions. Do not hide them inside an undefined sample approval.
Change record
Identify each revised model, resin, surface or tool decision. State which earlier evidence remains applicable and which needs another check.
Tooling terms
Confirm prototype-tool ownership, modification, storage and any transfer assumptions. No universal tool package or life is implied.
Production bridge
Ask what additional work or evidence is required before repeating the part. A prototype offer need not include all production-release scope.
05 / ACCEPTANCE RECORD
Keep a short record of the decision and its limits.
The record should let another reviewer understand what was evaluated without seeing this enquiry conversation.
| Record | Include | Reason |
|---|---|---|
| Identity | Part, revision, material and sample quantities. | Identifies what was reviewed. |
| Condition | Tool/route and completed operations. | Defines represented state. |
| Checks | Features, references, methods and outcomes. | Explains the decision basis. |
| Limitations | Open issues and production differences. | Prevents unsupported transfer. |
06 / QUOTATION BRIEF
Quote the sample purpose and the next approval step.
Samples with different material, tooling or evidence are not the same offer. Specify the decision before comparing price and timing.
Provide
Send files, exact resin or selection needs, sample quantities, critical interfaces, application or appearance reference and destination.
Confirm
Ask what tooling, setup, iterations, sample checks, reports and secondary work are included. Identify the work needed for later production separately.
Agree
State the approval owner, change process and next hold point. Minimum quantities, capacities and schedule are proposal-specific rather than general sample promises.
07 / QUESTIONS
Before ordering a molded prototype.
Approve the actual represented condition, not a broad process label.
Can a printed model approve injection molding?
It can answer its defined questions, but does not automatically represent molding material, tooling, surface or process behavior.
Does a prototype tool become the production tool?
Tool strategy, ownership, transfer and later work require actual proposal confirmation.
Does one sample approve every variant?
Only within explicit scope. Changes in material, color, geometry or tool configuration may require further evaluation.
How are sample iterations handled?
Record revisions, approval responsibility and which checks or tooling work are repeated. Confirm commercial scope.
What should the sample record say?
Identity, represented condition, checks, decision, limitations and the next production questions.
PREPARE THE NEXT DECISION
Send the decision the prototype must support.
Include CAD and drawing, intended sample purpose, exact resin if required, critical interfaces, tooling scope, appearance reference, evidence, quantities and destination.
