PROBLEM TO BE SOLVED: To provide a manufacturing method of ceiling material for vehicles, capable of molding two types of ceiling material, ceiling material having a convex or concave shape on the design surface and ceiling material having no convex or concave shape on the design surface, by using one mold without exposure of a parting line on the design surface, the ceiling material being excellent in usability and workability.SOLUTION: A manufacturing method of ceiling material for vehicles includes hot pressing a laminate material 6 composed of a surface material 9 laminated on a substrate 7, with a male mold 1 and a female mold 2. A mold for hot pressing has a thin plate 3 composed of a plate surface 31 in parallel with a molding surface 11 of the male mold 1 and an outside area surface 36 extending outward from the plate surface and a tangible expression object 4 formed of a plate piece 46 fastened to a plate surface 32 on the opposite side of the plate surface 31, or formed by boring in the plate surface 32. Between the opened male mold 1 and female mold 2, the tangible expression object 4 is opposed to the surface material 9. The laminate material 6 and the thin plate 3 having the tangible expression object 4 which is placed more adjacent to the male mold 1 are set, and then the molds are closed. Subsequently hot pressing is performed, and in parallel with molding of a ceiling material body 51, a concave or convex decoration pattern 55 of the tangible expression object 4 is transfer molded on a design surface 5a on the surface material 9 side.
【課題】意匠面にパーティングラインが出ず、使い勝手,作業性に優れ、意匠面側に凸部又は凹部の形状が有りのケースと無しのケースとの二種類の天井材を一つの型で成形対応し得る車両用天井材の製造方法を提供する。【解決手段】雄型1と雌型2とを備えて、基材7に表面材9が積層された積層材6を加熱プレス成形する車両用天井材の製造方法であって、雄型1の成形型面11に沿う板面31と該板面から外方へ延在する域外面36とを有する薄状板3と、板面31と反対側の板表面32上に固着した板片46で形成されるか、板表面32にくり抜き形成されるかした有形表現体4と、を具備する加熱プレス成形型を用いて、型開状態の雄型1と雌型2との間で、有形表現体4を表面材9と対向させ、且つ積層材6とこれよりも雄型1側に置かれる有形表現体4付き薄状板3とをセットした後、型閉じし、その後、加熱プレス成形して天井材本体51の成形と同時に、表面材9側の意匠面5aに有形表現体4による凹形又は凸形の加飾図形55を転写成形する。【選択図】図3
