eldec Induction U.S.A.
eldec’sSimultaneous Dual Frequency (SDF®) technology yields true profile hardening for complex shapes (i.e. gears, sprockets, CV joints). Applying massive power densities (up to 3 megawatt) using medium and high frequencies simultaneously. This results in super-short heating times, which yield precise contours and little or no distortion coming from heat bleeding into the core material.
