    • The powder slush molding method comprises a melting step of forming a molten resin film on a mold surface of a heated slush mold: a powder removing step of removing unmelted powder slush material from the mold surface; a heat retaining step of hermetically sealing the mold surface for a predetermined period of time, allowing the adhered unmelted powder slush to be melted by the remaining heat of the slush mold; a cooling step of cooling the molten resin film; and a taking-out step of separating the film-like molding from the mold surface.
      In the heat retaining step, the hermetic sealing of the mold surface can be effected by using a mold surface cover member (20) a powder sl ush material supply vessel, a feed material recovering vessel or the like.
    • 粉末搪塑成型方法包括在加热的搪塑模具的模具表面上形成熔融树脂膜的熔融步骤:从模具表面除去未熔化的粉末状釉料的粉末去除步骤; 一个将模具表面密封一段预定时间的保温步骤,允许粘附的未熔化的粉末浆料被搪塑模具的剩余热量熔化; 冷却熔融树脂膜的冷却步骤; 以及将膜状模制品从模具表面分离的取出步骤。 在保温步骤中,可以通过使用模具表面覆盖构件(20),粉末状料料供给容器,进料回收容器等来实现模具表面的气密密封。
