Same process, whatever the industry

How every job runs, from drawing to dock

01

Drawing review in 16 hours

Bill reads every drawing before it is priced and sends back price, lead time and the two or three changes that would make the part cheaper.

02

Free DFM before you commit

Tolerances, wall thickness, tool access and finish are questioned before metal is cut — not after the first article.

03

First article measured on a CMM

Every first article is measured against your drawing datums in a temperature-controlled measuring room before the run continues.

04

Shipped with a report

DHL, FedEx or UPS to your dock with commercial invoice, HS codes and a dimensional report per part.

Before you ask

Three questions buyers in every industry ask

Are you ISO 9001, ISO 13485 or IATF 16949 certified?

No. We are not certified to ISO 9001, 13485 or IATF 16949, and we will not pretend otherwise. What we do is measure every first article on a CMM and ship a dimensional report with every batch, so you can see what you are getting rather than trust a certificate.

Will you sign an NDA before I send drawings?

Yes. We sign your NDA before you send anything, or send you ours. Drawings are used to quote and make your parts, nothing else.

Is there a minimum order?

No. One prototype or ten thousand pieces — the quote and the inspection are the same. Many of our long-term customers started with a single part.

Ready for a quote?

Send the drawing — price and lead time within 16 hours. STEP, IGES, X_T, DWG, DXF or PDF.
No minimum order.
