What automotive CNC parts do you manufacture?

We machine engine brackets, sensor housings, transmission components, prototype fixtures, and custom jigs for automotive OEMs and Tier 1 suppliers.

What materials do you use for automotive CNC parts?

Aluminum 6061-T6, Steel 1045/4140, Stainless 304/316, and engineering plastics like PEEK and Delrin.

What tolerances are standard for automotive CNC machining?

Standard tolerances at ±0.05mm, with critical features held to ±0.01mm. We work to IATF 16949 quality standards.

Can you handle both prototypes and production runs?

Yes. One-off prototypes to 10,000+ production parts. Same quality system, same Zeiss CMM inspection regardless of volume.

Do you offer PPAP documentation?

Yes, we provide PPAP Level 3 documentation including FMEA, control plan, MSA, and capability studies for automotive customers.
