Abstract
Certain polyamide resin compositions make it possible to shorten the injection molding processing cycle for polyamide resins. The polyamide resin compositions are obtained by adding an external lubricant to polyamide resin granules composed of from 55 to 85% by weight of polyamide resin, 10 to 40% by weight of filler, and 0.3 to 2.0% by weight of at least one type of higher fatty acid ester type internal lubricant selected from among esters of higher alcohols and higher fatty acids and higher fatty acid partial esters of polyhydric alcohol compounds.
