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.

(1) The dimensional accuracy of powder metallurgy gears produced in large quantities is uniform, especially when carbide die is used.

(2) Because of the porosity in the material structure, it is helpful for the gear to run smoothly and self-lubricate.

(3) Powder metallurgical gears with blind angle can be made, which can eliminate undercutting and retracting grooves when cutting gears. When making this kind of gear by powder metallurgy, special support is needed at the blind end.

(4) Gear can be combined with other shape parts, such as cam, ratchet, other gears, etc., and integrated production can be realized by powder metallurgy process.

(5) Bevel gears, bevel gears with equal diameter, helical gears and other special tooth-shaped gears can be made.

(6) Standard involute gears can be made, which is simpler and cheaper than other methods.

(7) The ratchet wheel, like the gear, is easily manufactured by powder metallurgy and MIM. Root cutting should be avoided, and large radius should be allowed at the top and root of teeth.

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.
