Welcome to MJ Prototypes — your factory for prototypes, tooling and production.

Home/Industries/Automotive

Automotive

Functional prototypes, testing fixtures and low-volume parts for powertrain, EV and trim programmes.

Automotive schedules are unforgiving. Our value is a validated part in the test rig this month, then a stable supply for the pilot build next quarter.

We support battery enclosures, e-motor housings, sensor brackets, HVAC ducting, lighting bezels and interior trim, in both prototype and production-intent materials. Thermal and vibration fixtures are a regular part of our order book.

For pre-series work we run aluminium bridge tooling and record the process so the same part can move to a hardened steel tool with a documented PPAP-style submission.
