Abstract:
A manufacturing method for forming an interior vehicle component having an impact area and an interference area, said method comprising the steps of:setting a skin member on a die surface of an upper die of a mold press; lowering said upper die in a predetermined stroke toward a lower die; and forming a core member in contact with said skin member by supplying a first resin for a first portion of said core member to first predetermined portions of said lower die through a gate disposed in said lower die and supplying a second high-impact resistant resin, different from said first resin, to second predetermined portions of said lower die for a second portion of said core member, different from said first portion of said core member, said second portion of said core member corresponding to said impact area and/or said interference area, said second high-impact resistant resin having a ductile breakdown property that enables effective shock-absorption and suppression of the generation of sharp-edged fragments in said impact area and/or said interference area, wherein said first and second portions of said core member are in contact with said skin member, and wherein said first resin and said second high-impact resistant resin are injected simultaneously.
