A process for producing a thermoplastic resin molded product, comprising: a placement step of placing a thermoplastic resin particle compositionA into a cavityof a rubber diemade of a rubber material; a particle heating step of irradiating the thermoplastic resin particle compositionA in the cavitywith electromagnetic waves having wavelengths ranging from 0.78 to 2 &#x3bc;m through the rubber die, thereby heating to melt the thermoplastic resin particle compositionA; a filling step of filling a thermoplastic resinin a molten state into a spaceleft in the cavity; and a cooling step of cooling a thermoplastic resinin the cavitythereby obtaining a thermoplastic resin molded product.

Process for producing thermoplastic resin molded product and thermoplastic resin particle composition

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 &#x3bc;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.
