Mini Metal Gear
Mini metal gears are usually composed of gear teeth, tooth grooves, tooth root circles, tooth tip circles, wheel hubs, and other parts. Its structural design is compact, with small gear teeth and a module that may be as low as 0.2 or even smaller. In order to meet different transmission needs, there are different shapes of tooth profiles such as straight teeth, helical teeth, and bevel teeth, which can also be divided into cylindrical gears, bevel gears, and other types.
- Product Introduction
Product Introduction
Powder metallurgy mini metal gears are manufactured using advanced powder metallurgy processes. This process begins with uniformly mixing metal powder (such as iron-based, copper based alloy powder) with specific additives, and then applying high pressure in a high-precision mold to preliminarily shape the powder into a green body with a certain shape and density. Next, the billet is sintered at high temperature, causing diffusion and bonding between atoms, significantly improving the strength and density of the material, and ultimately obtaining a mini metal gear with an almost finished shape. Compared with traditional mechanical processing methods, powder metallurgy technology can achieve net or near net forming, greatly reducing material waste, lowering production costs, while ensuring high dimensional accuracy and good consistency of products, especially suitable for large-scale production of small and complex gear structures.
