Patent ID: 8293165

Claim:
A resin forming apparatus comprising: a silicone rubber mold having a cavity to be filled with a thermoplastic resin, wherein the material of the rubber mold has transmissivity for electromagnetic waves of 0.78 to 2 μm in wavelength; an electromagnetic wave generator, having a power consumption of at least 500 watts, for emitting electromagnetic waves of at least 0.78 μm to 4 μm, wherein waves in the range of 0.78 μm to 2 μm and waves in the range of 2 μm to 4 μm are present; and means for limiting the transmission amount of the emitted electromagnetic waves from said electromagnetic wave generator having a wavelength exceeding 2 μm and not for limiting the transmission amount of the emitted electromagnetic waves from said electromagnetic wave generator having a wavelength not exceeding 2 μm, wherein the rubber mold is positioned to be irradiated by the emitted electromagnetic waves limited by the means for limiting, wherein the emitted electromagnetic waves from said electromagnetic wave generator, whose transmission amount has been limited by said means for limiting, heat the thermoplastic resin more than the rubber mold and have power sufficient to maintain melted thermoplastic resin in the mold in a molten state.
