Abstract

The present invention provides an injection molding process of a thermoplastic resin which is capable of thin molding or precision molding by improving injection moldability, particularly releasability or fluidity, without deteriorating the characteristics of the injection molded article of the thermoplastic resin. The process for producing an injection molded product comprises injection molding a mixture containing a thermoplastic resin and a polyolefin wax, Wherein the mixture has L/L0≥1.05, the L being a flow length in the case where the mixture contains the polyolefin wax and the Lo being a flow length in the case where the mixture contains no polyolefin wax, the L and Lo being measured under the conditions of a mold temperature of 40° C and a resin temperature, Tr, as determined by the following equation: Tr=¾×Tm+100 (wherein Tm represents a melting temperature (° C) of the thermoplastic resin), using a spiral flow mold having a thickness of 1mm and a width of 10mm.
