CNC Machined EV Battery Enclosures for EV Teams
EV teams in Milwaukee need battery enclosures that are sealed, thermally managed, and precisely machined. We machine aluminum and stainless battery trays, module housings, and cooling plates with tight sealing surface tolerances. CMM inspection on every order.
EV-Grade Materials
Aluminum 6061/7075 and 316L stainless with material certs.
Sealing Precision
±0.0005" on o-ring grooves and sealing flanges.
QC Docs
CMM inspection reports on every EV battery component order.
Wisconsin's Manufacturing Muscle Powers Auto Supply Chains
Milwaukee's automotive contributions flow through its deep manufacturing base — A.O. Smith, Rexnord, and Modine Manufacturing supply thermal management and drivetrain components to automakers, while Harley-Davidson's headquarters and engine plant keep powertrain machining expertise sharp. The Chrysler engine plant in Kenosha (south of the metro) and GM's Janesville legacy maintain the region's OEM connections.
RivCut serves Milwaukee automotive suppliers with CNC machining, tight tolerances, and the PPAP documentation your OEM and Tier 1 quality systems require.

A Southeast Wisconsin EV team needed battery module enclosures with precise O-ring grooves for IP67 sealing, threaded inserts for cover bolts, and hard anodize for corrosion resistance. Teams near companies like Harley-Davidson trust this kind of precision and documentation rigor.
Every unit shipped with full documentation:
- CMM dimensional report — O-ring groove and bolt pattern verified
- Material cert with heat lot traceability
- Anodize process cert with thickness verification
- Dimensional layout per customer specification
What Milwaukee Automotive Buyers Should Know
Harley-Davidson and powersports machining demands cosmetic finish quality on visible engine components
specify surface roughness requirements (Ra 16-32 µin) on your drawings.
Wisconsin's manufacturing-engineering talent pool is deep
leverage local shops' expertise in fixture design and multi-op machining to reduce your per-piece cost.
Thermal management components for Modine require tight flatness tolerances on aluminum cold plates
verify your supplier's CMM capability and fixturing approach.
