Abstract

A process for injection molding a styrenic resin composition containing metallic fibers under the molding condition of: t </= 8.0 x 10<-3> x { (Tr - Tm)/(100 - Tm) }<2> (wherein Tm ( DEG C) represents a mold temperature, Tr ( DEG C) represents a molten resin temperature, and t (sec) represents a time taken for filling a mold with the resin composition). This process provides moldings having excellent surface quality and enables manufacture of housings, etc. of electronic and electric appliances having electromagnetic wave shielding properties.
