## Sourcing pain points we solve

Automotive machining spans two worlds: development, where an EV team needs five inverter housings next week and the design will change twice more, and production, where a bracket must arrive in thousands, identical and documented at a locked price. Most suppliers serve one world and fail the other. Volume programs demand SPC with Cpk ≥ 1.33, PPAP-style documentation and IMDS material declarations that prototype shops cannot produce. Meanwhile blanket-order economics punish any vendor who cannot hold unit price across a model year.

## Typical parts

- Inverter and controller housings (prototype)
- Battery module end plates and busbars
- Sensor housings and radar brackets
- Thermal management cold plates
- Validation and assembly-line fixtures

## Certifications & standards

- **IATF 16949**: We understand IATF 16949 supplier expectations — process control, traceability and corrective-action discipline aligned with automotive quality systems.
- **PPAP**: We support PPAP submissions with dimensional reports, material certs and process documentation in the format your SQE expects.
- **ISO 9001**: We understand ISO 9001 forms the baseline for automotive purchasing audits and run documented, repeatable processes accordingly.

_We understand and support these requirements; certification and documentation scope is confirmed per order — we do not claim to hold certifications on this page._
