PROBLEM TO BE SOLVED: To provide a manufacturing method of fixings for vehicle which can keep high designability for a long term and can be manufactured efficiently.SOLUTION: A vacuum forming mold 6 forms a main body of surface skin material 30 consisting of thermoplastic resin. Stitches 40 are added with thread 4 to the main body of surface skin materials 30. A part of the formation part of the stitches 40 in the back side of a surface skin material 3 is covered with a thermoplastic resin sheet material 5. An injection molding tool 7 having an upper die 72 and a lower die 71 is prepared. The surface skin material 3 is set on the set surface 72a of the upper die 72 so that the resin sheet material 5 faces with the lower die 71. The injection molding tool 7 is closed, thermoplastic resin is filled within a cavity 8 formed between the back side of the surface skin material 3 set on the upper die 72 and the die surface 71a of the lower die 71, and a base material 2 is provided.
【課題】高い意匠性を長い期間維持することができ、しかも、効率良く製造できる車両用内装材の製造方法を提供する。【解決手段】真空成形型6で熱可塑性樹脂からなる表皮材本体30を成形する。表皮材本体30に縫糸4でステッチ40を施す。表皮材3裏面側におけるステッチ40形成部分の一部を熱可塑性の樹脂シート材5で覆う。上型72及び下型71を有する射出成形型7を用意する。上型72のセット面72aに表皮材3を樹脂シート材5が下型71を向くようにセットする。射出成形型7を型閉じして上型72にセットした表皮材3裏面と下型71の成形面71aとの間に形成されたキャビティ8内に熱可塑性樹脂を充填して基材2を得る。【選択図】図7
