Plasma Atomization Production Unit

Our team of engineers, scientists and technicians have developed this patented technology for producing a highly pure spherical metallic powder for a multitude of application in the biomedical and additive manufacturing fields. A small wire is fed to the chamber, where three RPT plasma torches impinge on the surface of the wire at 3-4 times the speed of sound to both melting the wire and to finely atomize the metal, forming small droplets, which solidying as the powders fall down the tall chamber filled with argon.

This system was operated by PyroGenesis for many years before the company entered into a joint venture which ultimately led to the sale of the system to AP&C in 2006. The Plasma Atomization technology platform is now the industry standard for producing spherical metal powders for additive manufacturing techniques like 3D Printing. AP&C sold their powder business to ARCAM, a supplier of 3D Printing units in 2013.
