Abstract

The present invention provides a method for producing molded articles by joining primary molded parts by injection welding, by which a molded article composed of primary molded parts that are joined with high weld strength can be produced. The present invention relates to a method for producing molded articles including a welding step of injecting an injection welding material containing a polyamide around or between butt weld portions of primary molded parts disposed in face-to-face contact, so as to weld the primary molded parts together to form a molded article. The polyamide contains dicarboxylic acid units and diamine units. This polyamide further contains triamine units in an amount of 0.05 to 1 mol % with respect to the total dicarboxylic acid units.
