Abstract
By application of induction heating for thermal disconnecting of prestressed dies it is possible to produce high temperature gradients in the body of the die. By computer simulation a so-called "bottleneck"-effect was detected. This effect complicates the disconnecting of the insert. As convenient solutions are considered a suitable temperature-time course and variations of geometrical design.
