Auto Starter Housing

Precision aluminum die casting engineered for high sudden torque loads, strict bearing coaxiality, and optimal dimensional stability for flawless powertrain integration.

Manufacturing Challenges We Control

Starter housings require exceptional precision to prevent motor binding, gear wear, and assembly misalignments.

Bearing Coaxiality

Misaligned rotor bearings cause premature motor failure and excessive noise. We utilize single-setup CNC machining to guarantee strict concentricity and true position for all internal bearing bores.

High Torque Rigidity

Starters endure severe, sudden torque loads during engine cranking. Our Moldflow-optimized designs ensure dense, void-free internal ribbing to provide maximum structural rigidity without adding unnecessary weight.

Mounting & Gear Alignment

Improper engagement with the engine flywheel leads to catastrophic wear. We maintain strict flatness and positional tolerances on the mounting flange to ensure flawless drop-in assembly and perfect pinion gear alignment.
