It is better to process gears by powder metallurgy or by cold heading and casting

Whether the gear is processed by powder metallurgy or cold heading or casting is a very precise part. The traditional process is difficult, complex, cumbersome and expensive, and cannot be produced in large quantities. At present, powder metallurgy technology can solve these problems well, and is more suitable for some strange, complex and precise parts. Next, Shenzhen powder metallurgy manufacturer zhongwei will give you an analysis of precision gears. Which is better for powder metallurgy processing or cold heading casting?

1： Which is better for precision gear powder metallurgy processing or cold heading processing? In fact, cold heading is an extrusion process. The presence of a boss during extrusion may cause uneven extrusion of parts. For precision parts like gears, the teeth are relatively precise and the mold is easy to be damaged, which is not suitable for technology. The powder metallurgy processing technology and near-net forming technology are very suitable for one-time forming, mass production and production cost saving.

2： Which is better for precision gear, powder metallurgy or casting? In fact, gears can also be made by casting, but the casting process is complex and there are too many post-processing steps, so the precision of gears is not high enough and the production efficiency is not high, thus increasing the production cost of gears. The gear can be rapidly formed by powder metallurgy processing, and can maintain the accuracy, hardness and other properties of the gear. It can be produced and processed in large quantities to reduce production costs. With higher efficiency, better gear performance and durability, the casting process is more suitable for manufacturing large products.

Gear is a kind of precision component, which is widely used in the fields of automobile, consumer electronics, mechanical equipment and communication base stations. Especially in the field of automobile, automobile gears are basically processed by powder metallurgy. Facts have proved that the gear manufactured by powder metallurgy technology has better effect and more stable performance.
