Precision CNC Machining for Automotive Teams
Automotive companies in Vallejo need parts that are repeatable, durable, and cost-effective. A drivetrain housing that's off by 0.003 inches affects assembly fit and seal performance. We machine aluminum, steel, and stainless to tolerances as tight as ±0.0005 inches with full 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.
