Parts, Springs, and Equipment You Can Source
Vetted supplier network
North America RFQ support
Quality documents available
Prototype to production
Built for engineers and buyers
Get manufacturable parts into assembly without unnecessary back-and-forth.
Send your drawings, CAD files, material requirements, finish specifications, and quantity targets. We match the job to the right vetted supplier network resources, then review manufacturability, tolerance risk, workholding, secondary operations, inspection needs, and cost drivers before production begins.

Quality and delivery
Quality Documents Buyers Expect
Inspection Report
Dimensional inspection records can be supplied for critical features, first articles, production lots, or customer-defined checkpoints.
Material Certificate
Material certs can be requested for metal, plastic, spring wire, heat-treated material, and other traceability-sensitive orders.
COC / COA
Certificates of Conformance or Analysis can be provided when the PO, drawing, or project quality plan requires them.
Sourcing controls
Built to reduce RFQ risk before parts move into production.
Supplier Review
RFQs are matched to supplier resources based on process fit, material experience, inspection capability, finishing access, and repeat-order readiness.
Quality Planning
Critical dimensions, tolerance risk, material certificates, inspection reports, COC, COA, and first article needs are reviewed before quoting assumptions are finalized.
Packaging and Shipping
Parts can be planned for protected packaging, labeling, batch separation, receiving-friendly documentation, and practical export or domestic delivery support.
Repeat Order Support
Approved specifications, notes, documentation requirements, and packaging expectations can be carried forward for repeat production and maintenance orders.
RFQ process
Submit RFQ -> Review -> Quote -> Sample -> Production
- Submit RFQ Send drawings, CAD files, material, quantity, finish, target date, and any quality documentation requirements.
- Review We screen the request for manufacturability, supplier fit, tolerance risk, drawing gaps, and packaging needs.
- Quote You receive pricing, lead time, assumptions, sample options, and any clarifying questions before purchase.
- Sample Prototype or first article parts can be produced for fit check, performance review, and approval before scale-up.
- Production Approved parts move into short-run or production quantities with inspection, documentation, and repeat order support.
FAQ
Common RFQ Questions
What files should I send for a machining or spring RFQ?
STEP, STP, IGS, X_T, DWG, PDF, images, and sample photos are useful. Include material, quantity, finish, critical dimensions, load requirements for springs, and target delivery date.
Can you review drawings before quoting?
Yes. RFQs are screened for manufacturability, tolerance risk, missing specifications, finish requirements, inspection needs, and supplier fit before quoting assumptions are confirmed.
Do you support prototypes and production runs?
Support can include prototypes, samples, short-run production, repeat maintenance parts, tooling, fixtures, and approved repeat orders.
What quality documents can be requested?
Inspection reports, material certificates, COC, COA, first article review, dimensional checks, and load checks for springs can be discussed during RFQ review.
Can you help with obsolete or replacement parts?
Yes. Send drawings, photos, dimensions, equipment model information, samples, or marked-up sketches for reverse-engineered or drawing-based replacement part review.
