EFD Induction GmbH is one of the largest manufacturers of induction - hardening systems , with sales, service and manufacturing facilities and production development centers worldwide. EFD Induction is number one in Europe.
EFD Induction is a holding company and is headquartered in Skien ( Norway ). In more than 25 branches it employs around 1000 people in 20 different countries worldwide, 150 of them at the location Freiburg im Breisgau (Germany), the company EFD Induction GmbH .
EFD is the abbreviation of Elva Fritz Düsseldorf.
Further production locations are Grenoble (France), Bangalore (India), Shanghai (China), Madison Heights (USA) and Bucharest (Romania).
The company's main customers come from the automotive , electrical and mechanical engineering industries .
The EFD Group develops and supplies systems and frequency converters for heat treatment, in particular for hardening , soldering , pipe welding , straightening and many other industrial applications.
history
The Fritz Düsseldorf GmbH company with the company logo FDF was founded in 1950 by the engineer Fritz Düsseldorf in Freiburg.
The first turnover was achieved with individual hardening orders for the neighboring industry in the Black Forest region , whereby the first universal induction hardening machine could already be manufactured and sold in the founding year. In the 1970s, the second generation of the family, under Manfred Düsseldorf, also a mechanical engineer, took over the management and developed FDF into the leading manufacturer of systems for inductive heat treatment in Europe .
In 1996 FDF merged with the Norwegian company ELVA Induksjon as , which had become famous in the 1980s for its transistorized and mobile induction heating systems . The mechanical engineering for induction hardening systems has been operating under the name Elva-Fritz Düsseldorf GmbH since then .
Today the Norwegian EFD Induction as is responsible for the development and production of frequency converters up to 2000 kW / 400 kHz under the roof of the EFD Group . Furthermore, inverter in Grenoble (France) and Bangalore made (India).
In 1997 the previously integrated contract hardening shop was transferred to an independent company with the name Lohnhärterei Fritz Düsseldorf GmbH and from 2007 had the name EFD Härterei F. Düsseldorf GmbH . The location of this hardening shop has been in Freiburg-Hochdorf since 1998.
The hardening shop was sold at the end of 2011 and renamed VTN Fritz Düsseldorf GmbH on January 1, 2012 .
particularities
The company has further developed inductive heating and laser hardening in many technical applications around the world, such as: B. also hardening under protective gas . As a result, EFD Induction has many national and global patents . Using the technology of inductive and conductive surface layer heating , workpieces can be partially hardened. The hardening system can be integrated directly into a production line.
From an ecological point of view, inductive hardening can save considerable energy compared to conventional hardening in the oven.
