INJECTION-WELDED POLYAMIDE RESIN MOLDING

摘要

PROBLEM TO BE SOLVED: To provide a polyamide resin molding improved in welding strength in a molding produced by welding/integrating the polyamide resin moldings by an injection welding method. SOLUTION: In the injection-welded polyamide resin molding, on the surface of at least one primary molding formed from a primary molding material, a secondary molding material different from the primary molding material is injection-molded, and the primary molding and a molding part made of the secondary molding material are integrated by welding. (1) The primary molding material is a polyamide resin composition obtained by blending 0-100 pts.wt. of a component (B): a thermoplastic polymer other than a polyamide resin with 100 pts.wt. of a component (A): a polyamide resin. (2) The secondary molding material is a polyamide resin composition obtained by blending 0.1-40 pts.wt. of a component (D): a saponified ethylene-vinyl acetate copolymer, and 0-200 pts.wt. of a component (E): an inorganic filler with 100 pts.wt. of a component (C): a polyamide resin.
