Modern automotive manufacturing, particularly for electric vehicle systems, requires components with complex geometries, tight tolerances, and consistent quality across production volumes. Our 5-axis CNC machining services operate under IATF 16949:2016 quality management systems, supporting automotive tier suppliers and vehicle manufacturers with precision components since 2014. Our facility operates 12 five-axis machining centers with palletized automation, enabling unattended production for volumes from prototype through series production. We support commercial procurement programs requiring APQP, PPAP, and full production part approval documentation.

We apply ISO 2768-mK for general features, with tighter tolerances per customer drawing specifications. Critical sealing and mounting features typically use ±0.02mm true position, with bores held to H7 tolerance.
Yes, we provide full PPAP Level 3 documentation including dimensional results, material certificates, process flow diagrams, PFMEA, control plans, and capability studies (Cpk > 1.67 for critical characteristics) as required by automotive customers.
Prototype parts: 7-12 working days from drawing release. Production parts: 20-30 working days for first article submission, with ongoing production releases scheduled per customer pull signals.
We provide passivation for stainless steels, anodizing and chromate conversion for aluminum, zinc and nickel plating, powder coating, and e-coating through approved automotive supply chain partners, all with PPAP documentation.
