Can I send a rough requirement before final drawings are ready?
Yes. Send your current assumptions first, then mark pending items clearly so we can return a provisional quote scope.
Share your application, target specs, and quantity plan. We will respond with practical engineering and sourcing support.

Please include screw type, diameter, lead, stroke, load, drawings, STEP files, and quantity timeline.
NDA signing supported prior to drawing uploads.

| Required Item | Example | Why It Helps |
|---|---|---|
| Target screw type | Micro RV / inverted RVi / recirculating / custom shaft-nut | Quickly narrows the viable manufacturing and inspection route. |
| Envelope and travel | OD, lead, stroke, total length, nut style, mounting space | Confirms whether standard, inverted, or custom architecture fits. |
| Load and life target | Peak/continuous axial load, speed, duty cycle, L10 target | Drives model sizing, material choice, heat treatment, and preload recommendation. |
| Precision and quality files | Backlash target, lead accuracy, MTC, inspection report, AQL | Aligns quote scope with compliance, validation, and buyer audit needs. |
| Commercial scope | Prototype qty, annual forecast, destination, Incoterm, ship date | Aligns packaging, documents, and shipping plan early. |
Yes. Send your current assumptions first, then mark pending items clearly so we can return a provisional quote scope.
Use a revision-controlled change request with effective lot and impact scope agreed by both teams.
Yes. Please list required document types in the RFQ stage so they are included in validation and delivery planning.
If your team needs a fast start, use this structure in the first email. It improves quote precision and reduces clarification cycles.
| Output | Purpose | Buyer Action |
|---|---|---|
| Model and architecture direction | Narrow viable screw architecture against load, stroke, envelope, and precision assumptions. | Confirm baseline model path before cost-detail discussion. |
| RFQ clarification list | Close data gaps that affect pricing and lead-time accuracy. | Return missing values and drawing references in one reply. |
| Validation recommendation | Define sample test scope and acceptance evidence for technical sign-off. | Align internal engineering and procurement gates before PO. |
