Abstract: A resin forming method and a resin forming apparatus for obtaining a resin formed product, by filling a cavity of a rubber-made mold with a thermoplastic resin, and cooling the thermoplastic resin. When filling the cavity with the thermoplastic resin, an electromagnetic wave generator is used, and electromagnetic waves having an intensity peak in a wavelength region of 0.78 to 2 ?m are irradiated to the thermoplastic resin from the surface of the mold, and thereby the thermoplastic resin is heated selectively from the mold. The thermoplastic resin is an ABS resin which either a noncrystalline thermoplastic resin, or is a rubber modified thermoplastic resin.

Abstract: The present invention presents a resin forming method and a resin forming apparatus 1 for obtaining a resin formed product, by filling a cavity 21 of a rubber-made mold 2 with a thermoplastic resin 3, and cooling this thermoplastic resin 3. When filling the cavity 21 with the thermoplastic resin 3, electromagnetic wave generating means 4 is used, and electromagnetic waves having an intensity peak in a wavelength region of 0.78 to 2 ?m are irradiated to the thermoplastic resin 3 from the surface of the mold 2, and thereby the thermoplastic resin 3 is heated selectively from the mold 2. The thermoplastic resin 3 is an ABS resin which either a noncrystalline thermoplastic resin, or is a rubber modified thermoplastic resin.
