Vacuum furnaces


Optimum vacuum solutions from a single source for your vacuum furnace applications

Every day we come into contact with products that were manufactured in vacuum furnaces: Gears in automotive transmissions, specially hardened drill bits for industrial or DIY applications. High strength materials are difficult to produce without vacuum.

The components to be processed are heated in a vacuum furnace while vacuum pumps generate a low-oxygen atmosphere. This prevents any oxidation of the components. Vacuum furnaces are used in many different industrial applications, such as vacuum sintering for the production of hard metals for the tool industry or vacuum soldering for the production of vacuum switching chambers for the electrical industry. Vacuum hardening is used for high-alloy steels, such as those used for gear manufacturing by the automotive industry.

The advantages of vacuum
The vacuum in the furnaces acts as a protective atmosphere that prevents oxidation of the components. Vacuum sintering improves the surface quality of the components. This considerably reduces the need for mechanical reworking. The mechanical properties are also optimized through higher density, lower porosity and higher strength. In vacuum soldering, a high joint quality is achieved through the improved strength of the soldered seam. In addition, vacuum soldering ensures the high reproducibility of the process. Vacuum hardening is used to minimize distortion while also ensuring excellent surface quality. Another advantage of this process: The high surface quality allows direct nitriding after hardening.

Comprehensive portfolio for vacuum furnaces
Pfeiffer Vacuum offers a very large product portfolio, particularly for vacuum furnace applications. This ranges from vacuum pumps for evacuating furnaces to pressure measurement equipment, and from calibration pumping stations to leak detectors for locating leaks. With our components and valves you get the complete vacuum equipment from one source.
