Vacuumschmelze
As early as 1914, the first vacuum melting furnace laid the cornerstone for today's VACUUMSCHMELZE. VACUUMSCHMELZE GmbH & Co. KG (VAC) was founded in 1923 with its headquarters in Hanau. Alloys have been molten industrially in a vacuum since 1923. With more than 4,500 employees and production sites and sales offices in more than 40 countries, the company is globally ACTIVE today. Annual sales amount to approx. 340 million Euro. The large number of patents – more than 600 – underlines the great importance of development and research work at VAC.
Product Range
VAC develops and produces preponderant special magnetic materials and products derived of them. The company is a supplier to various industries such as the aircraft, automotive and aerospace industries, medical technology the watch industry or the power electronics industry.
The company is divided into three business units: Materials and Parts, Cores and Components and Permanent Magnets. VACUUMSCHMELZE is therefore one of the few companies in the world which produces the whole range of magnetic technology – from soft magnetic products to the strongest permanent magnets world-wide. All important key industries use quality products from VAC and benefit from the highly specialised development competence already in the conception of new applications.
In the automotive industry, for example, VACUUMSCHMELZE is represented in engine management, in ABS systems or also in effective fuel injection. In addition to transmission antennae for KEY-LESS-ENTRY and GO systems, VAC also supplies ESP sensors to the automotive industry.
In installation technology, VAC co-operates with switch manufacturers to protect persons in the home. Residual current circuit breakers are equipped with toroidal cores from VAC, as well as anchors and yokes made from VACOPERM®. These detect the slightest fault currents and interrupt the circuit.
VAC is also strongly represented in drive engineering. Permanent magnets in servo and linear motors as well as inductive components in frequency converters for motors provide speed, economy and operational reliability in the applications.
Magnetically shielded rooms and permanent magnets are used in advanced medical equipment such as state-of-the-art MEG (Magneto-Encephalography) or MRI (Magnet Resonance Imaging) systems.
VAC is also represented in transportation technology. The smaller and lighter components in transportation technology become, the more cost-effectively payload can be transported. Auxiliary converters protect the operation of air conditioning units and battery chargers in high speed trains such as the German ICE. Single plates and plate packages of CoFe alloys enable significant weight reduction for auxiliary power units in aircraft.
