An injection-moulding device is disclosed, comprising at least first (1) and second (3) mould parts, defining a mould cavity (4), wherein at least one of the mould parts comprises heating means, for heating the mould part in the vicinity of a mould cavity surface, said heating means comprising an inductive coil (18) having a plurality of windings and being powered by an oscillator. The heating means further comprises a thin top member, which functions as a susceptor for electromagnetic energy emitted by the inductive coil, which is placed in grooves in a carrier member. An intermediate member is placed between the top member and the carrier member. The intermediate member does not function as a susceptor to any grater extent, but provides mechanical stability while allowing the heat generation to be concentrated to the top member. |
