Automotive Gearbox Cover Die Casting Parts

The automotive transmission cover is a critical structural component within the drivetrain system, demanding exceptional strength, sealing integrity, and heat resistance. We employ high-pressure die casting technology using premium aluminum alloy raw materials to achieve a dense structure with low porosity and dimensional stability. Surface processes including deburring, sandblasting, machining, and precision milling of sealing surfaces ensure component reliability under the high-temperature, high-load conditions of the transmission environment.

Products undergo rigorous leak testing, CMM inspection, and fatigue endurance testing to meet OEM quality standards. They are compatible with automatic transmissions (AT), dual-clutch transmissions (DCT), and continuously variable transmissions (CVT) across multiple vehicle models.
