Induction Hardening
Induction hardening has considerable advantages compared to other surface hardening processes. The heat is only generated where it is functionally needed: In the surface layer. The high-precision process thus causes fewer distortions, enables process data acquisition at part level thanks to single-work-piece-flow and at the same time consumes significantly less energy than case hardening or flame hardening processes. Powered by green electricity, induction hardening enables CO2 emission-free production.
Induction hardening 2.0 - the SDF® process from eldec
With Simultaneous Dual Frequency, also known as SDF®, eldec offers a very special hardening process that is primarily used for complex workpiece geometries. A medium frequency is superimposed on a high frequency so that both frequencies act on the component at the same time. This technology ensures that certain areas of gears, for example, are heated evenly even though they are at different distances from the inductor. With SDF® hardening, a surface can reach the required temperature at the tooth root and tooth tip so that the entire workpiece is hardened true to contour. The result: absolute precision, uniform depth and temperature level.
