Resources and Documents
The documents a buyer or engineer needs before an RFQ: tolerance guidance, DFM rules, material notes and the records we can supply with an order.
We do not publish a downloadable PDF library yet, because a download that 404s or contains unverified numbers destroys trust faster than no download. Instead, the technical content lives in the knowledge base and in the specification tables on each product and capability page, where it can be kept accurate.
If you need a formal capability statement or a document for supplier qualification, ask directly and we will assemble the records we can actually issue — first-article reports, material certificates and dimensional data — in one package.

If you only need one number — a tolerance, a material choice, a cost driver — the knowledge base answers it directly and is easier to search than a brochure.
Tolerance capability
What tolerance bands actually mean, which features they apply to, and where thermal expansion takes over.
