MOLDED ARTICLE HAVING WELD PART

摘要

PROBLEM TO BE SOLVED: To provide a polyarylene sulfide resin molded article of which the weld part has markedly improved characteristics. SOLUTION: A resin composition based on a polyarylene sulfide resin is injection-molded in a mold at a temperature of 80-130 deg.C to obtain the molded article having the weld part of which the calorific value of cold crystallization is 0.5 J/(polyarylene sulfide resin) g or more.
