A compacted PM part is heated in a furnace up to about (typically) 2100 F, after which it might move on to various secondary operations. By sintering, it is easy to produce completely identical batches of parts, with very small deviation of sizes, for example, pistons and rod guides for shock absorbers production. Expensive tools and equipment are necessary for powder handling and manufacturing, as well as skilled personnel. The powder metallurgy process is a manufacturing process that uses a machine called a compactor to reduce the size of metal powder. There are a number of secondary operations. This technique is particularly used with pure metals in a vacuum. In contrast to other methods, it has the ability to produce particles on a microscale, which allows for very high purity levels even when large quantities are produced. In theory, the technique is applicable to any metal that can be melted and is commercially used to produce iron, copper, alloy steels, brass, bronze, low-melting-point metals such as aluminum, tin, lead, zinc, and cadmium, and, in some cases, tungsten, titanium, rhenium, and other high-melting-point materials. Sintering is a general term for the densification process and phenomenon of powder or green billet at high temperature.To be specific, with the increase of temperature and the extension of time, solid particles bond with each other, and grains grow up.
