PURPOSE:To enable molding to be performed even in low temperature by injecting a resin composite containing an imide compound in a specific amount that is selected from a group consisting of bisimide or the like and the metallic salt thereof relative to polyarylene sulfide resin. CONSTITUTION:To polyarylene sulfide resin of 100 pts.wt. a resin composite is injection-molded which contains one or two or more imide compound of 0.1-100 pts.wt. selected from bisimide or the like and metallic salt thereof represented by following formula. In the formula, R<1>, R<2> represent 4-22C alkyl group or alkenyl group respectively, and 4-6C cycloalkyl group or the like and A<1>, A<2> represents a single bond or a phenylene group. The resin temperature in injection molding is preferred to be 280-400 deg.C, and the injection pressure is to be 500-1300kg/cm<2>, and the injection is carried out at high pressure and high speed, resulting in obtaining a molded item with uniformity and fine luster, on the contrary, at low pressure and low speed, resulting in obtaining a molded item with small warpages or flashes. |
