Core Advantages

1. High-Precision Meshing

Precision powder metallurgy mold forming, tooth profile tolerance ≤0.02mm, ensures smooth meshing with sun gear/ring gear, low transmission noise (≤45dB).

2. Superior Wear Resistance

Oil-impregnated self-lubrication design reduces friction by 40% compared to traditional gears; sintered high-density material extends service life by 30%.

3. Cost-Efficient Mass Production

One-step mold forming without secondary machining, mass production efficiency increased by 50%, unit cost reduced by 20%-30%.

4. Customizable Performance

Material formula and sintering process can be adjusted for different load/speed requirements (torque range: 5-500 N·m).

Application Scenarios

Automotive Industry Industrial Machinery Home Appliances
Automotive automatic transmission planetary gear sets Servo motor planetary reducers Washing machine pulsator drive gearboxes
EV drive motor gear systems CNC machine tool feed systems Refrigerator compressor gear systems
Seat adjustment/side mirror adjustment gearboxes Robot joint transmission mechanisms Air conditioner swing motor gears

Production Process

1. Powder Mixing:  Cu stom material formula blending, ensuring uniform powder composition.

2. Precision Pressing:  High-pressure mold forming (300-600 MPa) to ensure initial gear shape.

3. Sintering:  Sintering at 1050-1150℃ in a protective atmosphere (N₂) to enhance density.

4. Sizing & Finishing:  Precision sizing of tooth profile/inner hole to meet tolerance requirements.

5. Surface Treatment: Optional oil impregnation/plating/phosphatization for lubrication/corrosion resistance.

Quality Assurance
