The core advantages of powder metallurgy gears are near net forming, material saving, labor saving, low cost, and suitability for large quantities.

Mechanical method: including solid crushing and liquid crushing. Solid crushing is the process of rolling or vibrating a cylinder to impact and crush materials into powder using steel balls, suitable for brittle metals and alloys; Liquid pulverization is mainly the atomization method, which disperses molten metal into mist like droplets through high-pressure gas, liquid, or high-speed rotating blades. After cooling, it becomes powder and is suitable for metals with low melting points
