Engineering feedback that makes your part faster and cheaper to build.
Our Process
From CAD file to parts on your dock.
Step 01
Send Your Files
Upload a STEP or Parasolid model and a PDF drawing with your tolerances, materials, and finish callouts. Building an assembly? Send the BOM too — we quote turnkey.
Step 02
DFM Review & Quote
Our process engineers review every job before it's priced. If a small design change will cut your cost or improve quality, we'll tell you before we cut a single chip.
Step 03
First Articles, Verified
We machine, inspect, and document your first articles — measured on CMM and vision systems, with reports in hand — so production starts from proof, not hope.
Step 04
Scale Without the Ceiling
Approved parts move into automated, lights-out production that runs 24/7. Your volume ramps. Your lead times don't.

Questions, Answered
Machine Shop FAQ
What is your minimum order?
We specialize in complex, critical parts — the ones that have to be right every time, because your product and your reputation depend on them. Because of the engineering, automation, and quality systems we put behind every part, most of our work is on components with annual purchasing of $1M or more. If you have a critical part and you’re buying around $1M of it per year, that is exactly the kind of work we are built for.
What do you need from me to quote a job?
A 3D model (STEP, Parasolid, or IGES) and a PDF drawing with tolerances, material, and finish callouts, plus your quantities and target dates. For assemblies, include the BOM. The more complete the package, the faster and sharper the quote.
Do you handle prototypes or production?
We specialize in production and repeat orders. It can be high production or it can be low quantity but orders that repeat every month.
What tolerances can you hold?
If your drawing calls it out, we plan for it. Every critical feature is verified on CMM and vision metrology systems, and the inspection report ships with your parts — so you're not taking our word for it.
What industries and materials do you work with?
Medical device, analytical instruments, semiconductor, aerospace, small satellite, and EV programs. We routinely machine aluminum, stainless steel, titanium, and zirconium, and have developed specific expertise in plastics like Ultem 1000, PEEK, Delrin, Hydex, and grey PVC. Our finishing network covers everything from anodize to specialty processes like vapor polishing.
Can you help improve my design for manufacturing?
Yes — DFM is a core competency here, built over 38 years. Bring us in at design review and we'll flag the small changes that lower cost, improve quality, or shorten cycle time, then keep finding year-over-year reductions once you're in production.
What are your lead times like?
It depends on complexity and volume — but this is exactly why we automated. Lights-out capacity means production keeps moving around the clock, and your quote comes with a committed schedule we plan the floor around.
Do you do more than machining?
Yes. Mechanical assembly, process planning, finishing management, and engineering support — so you can hand us a drawing and receive a finished, inspected, ready-to-integrate part or assembly.
