CNC Milling for the Michigan Automotive Industry
We're 25 minutes from the Big Three and surrounded by the Tier 1 and Tier 2 supplier base that built metro Detroit. A meaningful share of our work is automotive prototype and validation milling. The parts that get a program from PPAP draft to a green-light release.

Why automotive companies work with Carpatians
Local to metro Detroit
Same-day pickup, walk-in problem-solving, and engineers stopping by with parts in their hand. The Tier 1 ecosystem still runs on people who can drive to each other.
Short prototype lead times
Most prototype brackets and fixtures move from STEP to first article inside a week. Material in stock for all common automotive alloys.
Low-volume validation work welcome
Runs of 10 to 500 parts for validation lots are routine. We don't push you toward a tooling spend you don't need yet.
Documented material traceability
DFARS-compliant materials with mill certs on request and supplier traceability kept on file with the job, useful upstream of PPAP and Tier 1 audit work.
