Vacuum furnace users are striving to increase productivity and reduce operating costs. Higher performance and reduced maintenance is now the target. Through use of dry-compressing vacuum pumps, this target can be achieved. This article will introduce the modern design of a dry-compression vacuum pump with cantilevered screw rotors and feature advantages for use in demanding vacuum heat-treatment applications including sintering, brazing and carburizing.

With hundreds of years of history, heat treatment of workpieces is a known and well-proven technology. The purpose of heat treatment is to modify or influence the properties of a material in a controlled manner.
