Powder Metallurgy Gear

Supply some powder metallurgy parts,

The process is 

prepare the powder, mix them, press the metal powder with high pressure machine, and then sinter them to get hard solid parts. 

Since it is formed by powder, the sizes are very precise. Accordingly, we don't need CNC machine these gear’s teeth and the out shape,

Then can reduce the machining process, and save the cost, in comparison with CNC machining from the bar or forging and casting.

Now there are many powder metallurgy parts used in auto parts, audio device, medical machinery, aerospace industry, and power tools.

Sometimes the process might be cheaper and easier for some parts made by casting or forging and by CNC machining,but need high quantity

 while we can think about using this process if some parts are hard to be machined.

such as some gear teeth, curve surface,and special feature,
