Metallurgy Gears PM Parts

Whether by weight or by quantity, the proportion of powder metallurgy (PM) p;and metal injection molding (MIM) p;gears is much larger than that of PM parts in other fields. Gears, ratchets and cams are all suitable for powder metallurgy, p;because, p;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 p;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 p;undercutting and retracting grooves when cutting gears. When making this kind of gear by powder metallurgy, special support is needed at the blind end.
