Precision CNC Machining for Automotive Teams
Detroit automotive companies operate on a scale and cadence that few other cities match. When GM or Ford issues a prototype PO, the supplier has days — not weeks — to deliver. A drivetrain housing that's off by 0.003 inches gets rejected at receiving inspection and delays an entire validation build. We machine aluminum, steel, and stainless to tolerances as tight as ±0.0005 inches with full IATF 16949-ready documentation.
Automotive Materials
We machine aluminum 6061/7075, 4140 steel, stainless, and engineering plastics — all with full material certs and traceability on request.
Tight Tolerances
We hold ±0.001" on general features and ±0.0005" on critical bores, journals, and sealing surfaces. Every part CMM verified.
Full Documentation
Dimensional inspection reports, material certs, and first article documentation — whatever your IATF 16949-aligned quality plan requires.
What We Machine for Detroit Automotive Teams
Detroit automotive programs demand precision, traceability, and speed. We deliver all three with every order.

EV-optimizedAutomotive R&D Prototypes
Rapid prototypes for OEM and aftermarket development. 1 to 50 pieces with fast turnaround and full dimensional inspection reports.
1–50 piece runsParts for Detroit Automotive Companies
Engine brackets, drivetrain housings, EV components, and more.
Engine Brackets & Mounts
Engine mounting brackets, accessory mounts, sensor bosses, and structural frames machined from aluminum and steel. Detroit OEM programs demand repeatable bolt-pattern tolerances across multi-hundred piece runs. We fixture for consistency.
Al 6061 & steelDrivetrain Housings & Cases
Transmission housings, differential cases, transfer case bodies, and gearbox covers machined from aluminum and ductile iron. Detroit's Big Three set the bar for bore location accuracy and sealing surface finish — we meet those specs.
±0.001" standardEV Battery & Motor Parts
Battery tray structures, motor housings, inverter enclosures, and thermal management plates machined from aluminum 6061 and 7075. Lightweight, precise, and ready for sealing and assembly.
EV-readySuspension & Steering Parts
Control arm brackets, knuckle components, and steering rack housings. Machined from forged aluminum and steel billets with the bore tolerances and press-fit finishes Detroit chassis programs require.
High-strength steelBrake Calipers & Components
Custom brake caliper bodies, bracket adapters, and rotor hats machined from 6061 aluminum and 4140 steel. Detroit performance and OEM brake programs need consistent piston bore fits across multi-hundred piece runs.
Anodize-readyPrototype Fixtures & Tooling
Assembly jigs, weld fixtures, and inspection fixtures for automotive R&D. Detroit teams use our fixtures for APQP validation runs, pre-production builds, and supplier qualification testing.
