Request for Quote
Get a Custom Manufacturing Quote
Send your files and requirements, and SR returns a documented custom manufacturing quote from its vetted supplier network. One request covers process scope, price, lead time and inspection.
- STEP, PDF, DXF, BOM
- Quote in 5-7 working days
- Automotive-grade suppliers
- Inspection managed by SR
Quick answer
A custom manufacturing quote is a supplier's documented estimate of price, lead time, process scope, tooling, materials, quality requirements and delivery terms for a specified part. To get one from SR, submit CAD data, a controlled 2D drawing, material grade, quantities, tolerances, finishes and inspection requirements through the RFQ form.
How it works
What to Upload for a Custom Manufacturing Quote
Upload CAD data, a controlled 2D drawing, and a BOM for assemblies. A complete package means fewer supplier assumptions and a quote closer to the final price.
A custom manufacturing quote is a supplier's documented estimate of price, lead time, process scope, tooling, materials, quality requirements, and delivery terms for producing a specified part or assembly.
| File | What it provides | Notes |
|---|---|---|
| STEP (.step,.stp) | 3D geometry for process and tooling review | Preferred neutral CAD format |
| PDF drawing | Dimensions, tolerances, GD&T, finish and notes | Must be the current revision; ASME Y14.5 is commonly used for GD&T |
| DXF (.dxf) | 2D profiles for sheet-metal and laser cutting | Include bend lines and material thickness |
| BOM | Part list, quantities and assembly structure | Useful for assemblies and multi-part orders |
Information that speeds up a manufacturing quote request
- Material alloy, grade, temper and governing specification.
- Prototype quantity, order quantity, quantity breaks and annual volume.
- Critical tolerances and which features are critical.
- Surface roughness as a drawing-defined Ra value, plus the measurement method.
- Finish, heat treatment, inspection needs and whether material certificates or MTRs are required.
- Delivery target, destination and compliance documents.
State units on every dimension, for example a bore of about 2 in (50 mm). Mixed metric and imperial callouts are a common source of quote uncertainty.

FAQ
Questions about quoting
Not covered here? Talk to an engineer before you upload anything.
Talk to an engineerWhat should a manufacturing RFQ contain?
Provide CAD, a fully dimensioned drawing, revision, material and condition, quantities, tolerances, finish, delivery target, inspection, certifications and compliance requirements. Complete inputs let suppliers quote scope, price and lead time without assumptions.
What can make a quote inaccurate?
Missing drawings, ambiguous units, unspecified finishes, incomplete quantities, unclear inspection and unpriced tooling or special processes commonly create quote uncertainty. State assumptions and exclusions in the quote so both sides see the same scope.
Should the RFQ state annual volume?
Yes. Annual volume and quantity breaks help suppliers estimate capacity, tooling amortization, material purchasing and production pricing. A prototype-only RFQ often returns a higher unit price than a quote that includes expected annual demand.
What quality documents should I request?
Depending on risk, request material certificates, a Certificate of Conformance, dimensional reports, CMM data, test results, traceability and first-article documentation. Name the documents in the RFQ so inspection scope is priced into the quote.
