Cylinder Head Cover

Lightweight aluminum die casting engineered for strict oil sealing, NVH reduction, and high-temperature engine environments. Manufactured to precise OEM geometric tolerances.

Manufacturing Challenges We Control

Preventing engine oil leaks requires strict management of gasket groove roughness, mating face flatness, and internal porosity.

Precise Oil Sealing

Oil leaks are the primary failure mode for head covers. We utilize multi-axis CNC machining to achieve strict flatness and precise surface roughness (Ra) within the gasket grooves, ensuring a reliable, long-lasting seal.

Porosity Mitigation

Micro-porosity can lead to oil weeping under pressurized, high-temperature conditions. We employ optimized gating systems and Vacuum HPDC to strictly control internal voids, verified by X-Ray flaw detection.

NVH & Thin-Wall Integrity

Valvetrain components generate significant noise and vibration. Our casting designs incorporate optimized ribbing to dampen NVH while maintaining a lightweight, thin-wall structure without cold shuts.
