introduction

High-Tolerance CNC Milling for Engine Components

We utilize advanced high-speed CNC machining centers to fabricate complex cylinder heads and engine blocks from premium alloys, meticulously managing intricate internal cooling galleries while maintaining strict dimensional stability across complex geometries.

Our simultaneous multi-axis milling capability ensures flat sealing surfaces and micron-level precision, guaranteeing reliable vehicle performance and durability under extreme, high-stress thermal operating environments. The EV scope is covered under EV components. These parts are machined to drawing as part of our automotive machining services.

Scalable CNC Machining for EV Powertrain Systems

DEK Automotive specializes in scalable precision manufacturing for critical EV powertrain components, providing tailored CNC milling and turning solutions for motor housings, stator supports, inverter enclosures, and complex, thin-walled battery cooling plates.

By integrating cutting-edge multi-axis centers with rigorous SPC process monitoring, we ensure a seamless and reliable transition from rapid prototyping to high-consistency, volume-series production.
