Durable Forged Transmission Components for Automotive & Heavy Equipment Applications

Durable Forged Transmission Components for Automotive & Heavy Equipment Applications

Product Overview

We manufacture precision-forged gearbox housings and differential cases using high-grade alloys and new condition dies for superior dimensional accuracy. Our components are engineered for :

✔ Automotive Transmissions (Passenger & commercial vehicles)
✔ Heavy-Duty Differentials (Trucks, tractors, mining equipment)
✔ Industrial Gearboxes (Wind turbines, marine propulsion)
✔ Off-Road & Military Vehicles (High-stress environments)

Key Features & Benefits

1. Superior Forging Quality

• New Die Sets for optimal dimensional consistency (±0.2mm tolerance)

• Closed-Die Forging Process enhances grain structure & fatigue resistance

• Material Options: 4140 steel, 4340 alloy, aluminum A356-T6

2. Performance Advantages

• 30% stronger than cast alternatives

• Excellent impact resistance at extreme temperatures

• Reduced machining requirements (near-net shape)

3. Custom Engineering Support

• CAD/CAM die design services

• Heat treatment customization (quench & temper, T6 aging)

• Balanced machining allowances (3-5mm standard)
