| 20090239023 | INJECTION-MOULD WITH INDUCTIVE HEATING, INJECTION MOULDING METHOD, OPTICAL INFORMATION CARRIER AND LIGHT GUIDE PLATE - An injection-molding device includes at least first and second mould parts, defining a mould cavity, wherein at least one of the mould parts includes a heating device, for heating the mould part in the vicinity of a mould cavity surface, the heating device includes an inductive coil having a plurality of windings and being powered by an oscillator. The heating device 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. | 09-24-2009 |
| 20090068306 | Moulding Device and Method - An injection-moulding device is disclosed, comprising at least first and second mould parts, defining a mould cavity, 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 having a plurality of windings and being powered by an oscillator. The mould part comprises a top member, at the mould cavity surface, and, beneath the top member, a carrier member comprising grooves for taking up said coil windings, wherein the top member resistivity is lower than 1.5*10 | 03-12-2009 |
