Why OpenSpindle
Built for automotive buyers
Real quotes, not estimates
Your part is quoted by independent shops set up for automotive work, so the price reflects the real job, not an automated estimate that changes later.
No sales gate
Upload a drawing and request quotes without a sales rep or account manager in the middle. Faster than the login-walled portals.
Prototype and motorsport friendly
Independent shops routinely quote single prototypes, race one-offs, and small aftermarket batches, not just high-volume production runs.
Compare multiple shops
See several independent shops set up for automotive work and compare quotes rather than taking a single price.
Trust
Certifications and standards that matter
For automotive work, the right certification depends on where the part is going. OEM production has strict quality gates, while motorsport, aftermarket, and prototype work is often far less certification-gated. Confirm the specific scope for your part.
IATF 16949
The automotive quality management standard, built on ISO 9001 with additional requirements for production and service parts. The baseline expectation for OEM and tier-one production supply chains.
ISO 9001
The general quality management baseline. Common on shops that do automotive work outside OEM production, and often sufficient for aftermarket, motorsport, and prototype parts.
PPAP
Production Part Approval Process, the automotive workflow for demonstrating that a shop can consistently make a part to print before volume production. Required by most OEM and tier-one customers on new parts.
Motorsport & aftermarket work
Motorsport, aftermarket, and prototype parts are usually less certification-gated than OEM production. Here the priorities are turnaround, material selection, and a shop that can iterate on a design, so judge shops on capability and communication rather than a certificate.
Questions
Frequently asked questions
Yes. Many shops on OpenSpindle focus on motorsport, aftermarket, and restoration work, which is usually less certification-gated than OEM production. For these parts, judge a shop on capability, materials, and turnaround rather than a formal automotive certificate.
