Manufacturing Processes & Capabilities
- High-Density Compacting & Atmosphere Sintering: Covers M0.2 to M1.5 modules via multi-action powder compacting presses and controlled-atmosphere sintering furnaces; tightly manages material shrinkage and sintered density for precise tooth profiles and low pitch errors.
- Precision Bevel Pitch-Cone & Bore Tolerancing: For 90° angular bevel transmissions, tooling strictly controls pitch cone angles, mounting distances, and shaft bore concentricity to ensure centered tooth contact patterns under heavy dynamic loads.
Features & Advantages
- High Torque Capacity & Impact Fatigue Resistance: Delivers high sintered density and shear strength, outperforming plastic gears in sustaining severe stall torque, shock loads, and heavy-duty output demands.
- Near-Net Shape Cost Efficiency & Uniformity: Sintering produces near-net shape gears with integrated keyways, steps, and complex profiles without expensive machining, providing tight batch-to-batch consistency for mass production.
- Self-Lubricating Porosity & Long Wear Life: The inherent microscopic porosity allows vacuum oil impregnation, generating a continuous lubricating film during operation to lower friction, reduce wear, and extend maintenance-free service life.
