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

Metal injection molding (MIM) is widely used in multiple industries that require small and precise metal components, thanks to its ability to form complex shapes, high precision, and wide material adaptability. The core application areas and specific scenarios are as follows

Metal powder should be fine, spherical, and of high purity, with a low oxygen content. The powder loading capacity should be controlled at 55% to 65%. If it is too high, it is prone to material shortage, and if it is too low, it is prone to deformation. The adhesive and powder should be well wetted, and the mixing should be uniform to prevent powder adhesive separation. The feeding must be thoroughly dried to prevent bubbles and delamination.

The core advantages of powder metallurgy gears lie in their high-volume production, low cost, self-lubricating properties, and integral structural molding. Therefore, they are primarily used in transmission scenarios with medium to low loads, high precision, and large quantities.
