Manufacture of plastisol skin

Abstract

Abstract PURPOSE:To obtain readily a hollow skin, by spraying a plastisol on a mold inner surface to form a thin film, allowing the film to gel, adding an additional plastisol on the inner surfaces of the gelled film, allowing the additional plastisol to gel, removing the excess ungelled plastisol, and heating both the gelled layers to melt to be integrated. CONSTITUTION:Colored plastisol is sprayed by a spray gun 12 on the inner surfaces of the mold 2 in a rotating box 3 to form a film 13, and by heating the mold 2 the film 13 is allowed to gel. Then, uncolored plastisol 14 is filled in said mold 2 having the colored and gelled plastisol 13, and by heating the mold 2 a gelled layer is formed in the mold 2. Then the mold 2 is rotated 180 deg. to remove the excess uncolored plastisol. In this case, the colored and gelled layers and the uncolored and gelled layer thereon remain on the inner surfaces of the mold 2. The mold 2 is heated to melt both the gelled layers to be integrated, and is cooled to obtain a skin 15.
