Whether by weight or by quantity, the proportion of powder metallurgy (PM) and metal injection molding (MIM) gears is much larger than that of PM parts in other fields. Gears, ratchets and cams are all suitable for powder metallurgy, because, in terms of powder metallurgy and MIM gears, besides low cost and high production efficiency, there are also the following advantages.

Powder metallurgy and metal injection molding have the characteristics of excellent surface roughness, uniform performance among parts and self-lubrication, which is especially advantageous for making gears and cams. Sintered cams with self-lubricating properties often have more durable surfaces than grinders. Powder metallurgy gears can be formed at one time, which not only saves cost, but also improves productivity.
