Abstract

A heating device for heating a hollow component may include at least one inner induction coil and at least one outer induction coil, each configured to be heated. At least one element may be configured to influence a magnetic field formed between the inner and the outer induction coil during the operation of the heating device. The element may be arranged between the inner and the outer induction coils. Regions of the hollow component may be thinner and the thinner regions may be configured to heat more quickly than the remaining thicker regions. The thinner and thicker regions of the component may allow even heating of the component to be achieved.
