High Precision Automotive Transmission Die Casting Parts Manufacturer,Aluminum Gearbox & e-Drive Housing Supplier

Automotive Transmission Die Casting Parts Manufacturer

Jinyuanfu Metal Products Co., Ltd. has been deeply engaged in high-performance aluminum die casting manufacturing for over 20 years.

We provide precision die-cast transmission components widely used in fuel vehicles, hybrid vehicles, and new energy vehicles (EVs), covering gearbox housings, differential cases, e-drive modules, and other critical drivetrain structures.

Core Advantages

1.  High-Density Vacuum Die Casting

Advanced vacuum die casting process ensures dense, porosity-free structures, meeting vacuum welding standards below 50 mbar for superior sealing performance.

2.  Excellent Fatigue Resistance

Using high-strength aluminum alloys, our parts exhibit outstanding fatigue resistance, dimensional stability, and reliability under high-speed, high-load conditions.

3.  Superior Dimensional Precision

Tooling accuracy up to ±0.01mm, with CNC machining parallelism and perpendicularity ≤0.03mm, ensuring perfect assembly fit and high transmission efficiency.

4.  Complex Structure Integration

Supports one-shot forming of complex holes, ribs, and threads, reducing machining steps and assembly errors.

5.  Versatile Surface Treatments

Available finishes: sandblasting, electrophoresis, anodizing, corrosion-resistant coating, enhancing both durability and appearance.
