Engineering Review Before We Quote — Not After
Every RFQ is read by a machinist before it is priced. We have been cutting Inconel and titanium since 2012; the DFM notes you get back are from people who have actually made parts like yours — not from a quoting algorithm.
Tolerance Reality Check
If a ±0.01mm callout only needs ±0.05mm for function, we tell you — and your price drops. If you need ±0.002mm, we tell you that too, and what it costs.
Tooling Access
We flag deep pockets, sharp internal corners and thin walls before they become scrap. Standard radius recommendations are free.
Material Optimisation
6061 vs 7075, 304 vs 316L, cast vs machined — we recommend the grade that meets function at the lowest landed cost.
Drawing Review
Missing datums, inconsistent GD&T, outdated surface finish symbols — caught before production, not after.
Engineering Hub — Read the Guides
Written by the people who quote your parts. No filler — tolerance budgets, material trade-offs, finish limits and inspection practice that survive contact with a real drawing.
