Abstract

PURPOSE: To manufacture the title molded article having excellent surface glossiness, by the injection molding of a mixture comprising a polyamide derived from hexamethylene isophthalamide (6I) and a reinforcing material comprising inorganic fibers, at a molding temperature to give an apparent melt viscosity of lower than a specific value.
CONSTITUTION: A resin mixture composed of (A) 50W90wt% of a 6I polyamide derived from (a) 30W100% of 6I component, (b) 0W50% of hexamethylene terephthalamide, and (c) 0W30% of hexamethylene adipamide, and (B) 5W50wt% of a reinforcing agent comprising inorganic fibers, is kneaded, pelletized, and injection molded. The injection molding is carried out at a temperature to give an apparent viscosity of the formula I (μa10 is melt viscosity (poise) at a molding temp. of T°C, under a shear rate of 10 sec-1; Ts is the softening point of the polyamide; 10°C≤T-Ts≤100°C). A reinforced polyamide molded article having a surface glossiness of ≥40% is manufactured by this process.
