Although they have shrunk, brown parts are still larger than what s desired in finished parts. The sintering process is carried out in controlled-atmosphere furnaces, often in vacuum furnaces, at temperatures high enough to weld the particles together, but below the melting point of the powders. A very large degree of shrinkage occurs during sintering. The finished part is near full density. If properly designed, molded, debound, and sintered, finished parts require no further finishing.
Parts are recyclable.
