Sample planning, acceptance criteria, and inspection record support for cycloidal reducer prototype programs.
| Program Metric | Typical Range | Procurement Value |
|---|---|---|
| Sample evidence | Inspection records plus buyer validation feedback | Evidence quality determines whether prototype results can support production decisions. |
| Revision loop time | Sample build, buyer test, DFM update, and re-sample | The calendar risk is usually the feedback loop, not only supplier manufacturing time. |
| Decision Point | Choose When | Verify Before Quote | Next Internal Step |
|---|---|---|---|
| Sample evidence is the first sourcing filter | Ideal for buyers moving from concept selection to sample validation. Use this path when sample evidence (Inspection records plus buyer validation feedback) is more important than starting from a generic gearbox size. | Evidence quality determines whether prototype results can support production decisions. Include prototype quantity and test plan in the first RFQ packet. | Compare OEM Capabilities |
| Mechanical interface risk is visible early | Define pass/fail thresholds before sample shipment. | Unusable sample feedback: Agree test method and report structure before shipment. | Send RFQ Package |
| Sample acceptance must be measurable | Use prototype planning when revision loop time must be confirmed against buyer-side machine tests. | Acceptance criteria change: Separate must-pass requirements from engineering observations before the next sample batch. | Plan Quality / Export Support |
| Phase | Engineering / QC Checkpoint | Buyer Output |
|---|---|---|
| Requirement baseline | Prototype quantity and test plan; Required inspection records. Confirm drawing revision, quantity, destination, and timeline in the same packet. | A quote-ready RFQ sheet that separates required performance from preferred options. |
| Engineering fit review | Define pass/fail thresholds before sample shipment. Separate supplier inspection records from buyer-side machine validation. Record open issues before sample cost and lead time are frozen. | A reducer shortlist and issue log for Prototype Validation Support. |
| Prototype or incoming validation | Measure sample evidence and revision loop time against the agreed method. Agree test method and report structure before shipment. | Inspection and test evidence with pass/fail limits, measured values, and revision actions. |
| Batch control and export readiness | Acceptance criteria change: tie the control plan to outgoing inspection, packaging, labeling, and shipment records. | Repeat-order package covering drawing baseline, CTQ records, packaging rules, forecast, and Incoterm. |
Manufacturing Evidence Pack
Use this pack to align sample release, production records, quality evidence, export paperwork, and revision control before moving from prototype discussion to repeat supply.

These images support product recognition and envelope review. They are not inspection reports, certificates, or measured test results.
Buyer Review
Tooth profile, pin wheel, eccentric shaft, housing datum, bearing fit, and output interface reviewed as one reducer system.
Artifact to Request
Process photos, CTQ dimension list, approved 2D drawing, CMM or critical-dimension record when available.
Release Status
Requires model-family approval
Buyer Review
Which material route and hardness target apply to this model instead of a generic catalog claim.
Artifact to Request
Material route note, heat-treatment target, hardness inspection field, and sample-lot traceability scope.

No certificate or test result should be displayed until approved. Keep the page useful by showing the review path, then attach real evidence during RFQ or after factory approval.
OEM RFQ
Share drawings, revision status, required records, sample scope, forecast, destination, and timeline so the factory-side review can separate technical risk from commercial assumptions.
Yes. Required records should be listed in the RFQ so they are built into the sample plan.
Document the test condition, measured result, suspected cause, and required design response before revising the sample.
Execution Route
Prototype Validation Support is part of the factory-side path. Buyers still need the product family, application context, sample plan, and quote packet connected in one thread.
Check reducer architecture, model family, envelope class, and CAD availability before the quote is treated as final.
Review the machine or robot axis context so torque, shock, backlash, stiffness, and validation risk stay tied to real use.
Move from fit review into DFM, sample validation, inspection records, packaging, and repeat-order control.
Use these links when the buyer is ready to send requirements, compare directories, or review sourcing guidance.
Inquiry Email
Include ratio, torque, backlash, interface drawings, quantity plan, and destination terms.
