    • 1. Physics of induction heating ■ Alternating current, that flows through a coil, leads to a time dependent magnetic flux around that coil. H ■ The magnetic flux creates eddy currents in a work piece that is located inside the coil . ■ The penetration of the induced current depends on the frequency. ■ Eddy currents are generated by the electrical resistance of the work piece.
    • 2. eldec history ■ 1982 Founded in 1982 by Dipl. Ing. Wolfgang Schwenk. eldec develops and manufactures inductors. ■ 1993 The product range continues to expand: eldec develops and supplies the first HF and MF generators with IGBT semiconductor transistors. ■ 1998 Founding of eldec Induction USA. This facility markets all eldec products, assembles generators and offers all services for the American markets, Canada, Mexico and South America. ■ 2000 Supply of the first SDF ® generators. A patented technology which is mainly used for truecontour inductive surface hardening of gear wheels. ■ 2004 €11 million turnover with the two facilities. ■ 2006 Completition of a worldwide unique pilot hardening system with a 3000 KW SDF® - Generator. eldec Inductors eldec MF, HF and SDF® Generators eldec USA, Auburn Hills
    • 2. eldec history ■ 2007 eldec reaches turnover of approx. € 12 million with 90 employees. ■ 2008 Introduction: MIND hardening machine range. ■ 2009 eldec establishes sales and service facility in China. Introduction of MICO product range. ■ 2010 Introduction of MIND-S product line. ■ 2011 Introduction of MIND-M product line. Additional floor space for production and assembly in USA. New production and assembly facility with additional 2000 qm in Dornstetten, Germany. Worldwide turnover approx. € 19 million with 135 employees. ■ 2012 Introduction of MICO-S. The MICO product line is complete. eldec reaches turnover of approx. € 21 million worldwide. ■ 2013 eldec becomes a member of EMAG Group. MICO product line MIND product line eldec Dornstetten
