Vacuum Sintering

Sintering is a very challenging application for vacuum pumps as during the dewaxing step the used polymer binder evaporate and partly crack. These vapors enter the vacuum pumps and could condense inside the pumps’ compression stage. Oil-sealed pumps operate unreliable and do require very frequent maintenance and service. Dry pumps will build up layers inside the compression stage over time and will require a regular cleaning step. The best pump choice for such application is the SCREWLINE, as by the moderate inner temperatures built-up of layers is reduced as the pumps compression can be manually cleaned by the user.
