What is powder metallurgy?
Powder metallurgy is a manufacturing process that produces highly precise parts by pressing powdered metals and alloys into a rigid mold under intense pressure. With the development and implementation of technological advances, powder metallurgy has become an essential process for the production of bushings, bearings, gears and a variety of structural parts. The key to the precision and success of powder metallurgy is the sintering process, which heats the parts and puts them under pressure so that the powder particles stick together. The temperature in sintering is slightly lower than the melting point of the primary metal, so that the powdered particles are connected to each other by bonds.
Powder metallurgy production process
The powder metallurgy process is an old and unique method for forming shapes and designs from ferrous and non-ferrous metals. Powder metallurgy has been used for thousands of years as a way to produce household items and tools. This method started as a way to mass produce products and parts in the middle of the first industrial revolution. Until the early 20th century, this process was used sporadically, but was not considered a viable manufacturing method. With the development of electricity and technological advances, powder metallurgy has found a place as a very efficient and productive method for producing parts with high tolerances and minimal waste.
