Smart Lock Lever PM Sintered Part
The powder metallurgy lever is a high-tech product with less chips and no chips. Although powder metallurgy gear levers are difficult to count separately among the entire powder metallurgy parts, the proportion of powder metallurgy gear levers in automobiles and motorcycles is far greater than that of powder in other fields, no matter in terms of weight or number of parts. metallurgical parts. Carry out in a high temperature furnace or a vacuum furnace with a protective atmosphere.

Long-term supply of high-precision smart lock levers for metal powder metallurgy structural parts.
The powder metallurgy lever is a high-tech product with less chips and no chips. Although powder metallurgy gear levers are difficult to count separately among the entire powder metallurgy parts, the proportion of powder metallurgy gear levers in automobiles and motorcycles is far greater than that of powder in other fields, no matter in terms of weight or number of parts. metallurgical parts. Carry out in a high temperature furnace or a vacuum furnace with a protective atmosphere. Sintering differs from metal melting in that at least one element remains in the solid state during sintering. During the sintering process, the powder particles become a metallurgical product with a certain porosity through a series of physical and chemical processes such as diffusion, recrystallization, welding, compounding, and dissolution. Therefore, it can be seen from the increase in the proportion of automobiles and motorcycles in the entire powder metallurgy parts that the powder metallurgy gear lever is in a position of rapid development in the entire powder metallurgy parts. According to the characteristics of parts, gears belong to structural parts, and the weight of structural parts in the whole iron-based parts is much larger than that of other types.
