The Vacuumschmelze (VAC) is a global business headquartered in Hanau its focus on the development, manufacturing and marketing of magnetic materials is. The company carries a wide range of products, ranging from soft magnetic materials to inductive components and permanent magnets . The main applications for the products are in the automotive and aerospace industries , automation technology or in energy conversion and distribution.

Company history

founding

Dr. Wilhelm Rohn, head of the physical test laboratory at WC Heraeus GmbH, developed a process for melting metals in a vacuum in 1913 .

With the outbreak of the First World War , the work had to be interrupted and further development was delayed by three years. The patenting for the "process for vacuum melting and tempering of metals and alloys", which should make it possible to replace expensive precious metals such as platinum or rhodium with cheaper base metals such as chrome-nickel alloys, did not follow until 1918. About five years after the development WC Heraeus outsourced the department with 50 employees by establishing Heraeus-Vacuumschmelze AG on July 1, 1923 under the direction of Dr. Rohn founded.

The product range was expanded in 1927 to include thermal bimetals with defined thermal expansion behavior and MUMETALL. It was the first soft magnetic nickel-iron alloy.

In order to be able to implement the order volume, Vacuumschmelze expanded its production area in 1929. In 1930 Vacuumschmelze had 84 patents.

In November 1933, after a long collaboration, Siemens & Halske took over 81.5% of the shares in Vacuumschmelze. As a result of further enlargements of the production area, the factory premises already comprised a total of 17,000 m² in 1939, on which 550 people were employed.

After 1943

With the death of Dr. Wilhelm Rohn on October 5, 1943, Vacuumschmelze lost its leading engineer. Vacuumschmelze suffered another setback due to the destruction of the Hanau plant during the war.

Three years after the end of the war, Vacuumschmelze was operational again with 479 employees. In 1948 the company developed the new soft magnetic alloy ULTRAPERM. n the times of the economic miracle , in the 1950s, Vacuumschmelze also expanded strongly and founded a company in Berlin.

The development of toroidal cores made of highly permeable alloys, spring materials for the watch industry and cobalt-iron alloys of the VACOFLUX series for the aviation industry also took place during this period .

Further developments from the Vacuumschmelze company were sheet metal stacks, permanent magnets , heating conductor materials for household appliances and industrial applications, inductive components , superconductors and rapidly solidifying materials. With the growing product portfolio, the company also opened new locations abroad. After the network of international sales offices that had existed for decades was expanded in the 1970s, the company also grew with international production locations: in 1994 in Malaysia, 1996 in the USA, 1997 in Slovakia, 2001 in China and finally in Finland in 2005.

Hartmut Eisele led the company from 2003 to September 1, 2014, which was replaced by Richard Boulter. The company has been run by Stefaan Florquin and Erik Eschen since June 2016. Erik Eschen has been running Vacuumschmelze alone since November 2018.

The VACUUMSCHMELZE group is now part of the Apollo Global Management portfolio .

Production sites

The company, which was founded in 1923, has its main production site in Hanau near Frankfurt, as well as other production sites in Slovakia , Finland , Malaysia and China . In addition, VAC has a global network of sales and application engineers who advise customers and interested parties in over 40 countries on site.

Product range

VAC's product range with over 800 patents is essentially based on soft magnetic alloys and rare earth permanent magnets. The products are offered in various refinement stages as crystalline , amorphous or nanocrystalline semi-finished products in the form of strips and wires, parts such as stamped / bent parts, sheet metal packages and toroidal tape cores , inductive components such as chokes or current sensors as well as magnets and magnet systems.

The products are used as components in many different fields of application in the processing industry. The most important are:

Electromobility:

  • Charging infrastructure
  • 48V electrical system
  • Rotor-stator systems for electrically powered premium sports cars and motorsport

Automotive:

  • Electric power steering and other auxiliary motors
  • Injection systems
  • Double clutch
  • Cooling systems
  • On-board network suppression

Aviation:

  • Rotor-stator systems for electric motors and generators

Industry:

  • Drive technology for industrial automation
  • Sensors
  • Inverter
