Abstract:
A method for manufacturing a three dimensional molded body comprising a surface material and a non-foamable urethane layer fixed on a back surface of said surface material, comprising steps of:horizontally positioning a flat resilient sheet;mounting a textile material on said resilient sheet so that a surface of a plastic film or a foamable slab material laminated on one surface of said textile material is faced upward;coating a reactive mixture of a non-foamable liquid urethane on said surface of said plastic film or said foamable slab material by spraying said reactive mixture thereon;placing said surface material on said liquid urethane elastomer so that said surface material covers said non-foamable liquid urethane on said flat resilient sheet;integrally pressurizing and compressing said surface material, said urethane, said textile material and said resilient sheet by an upper portion of a mold and a lower portion of said mold when said non-foamable liquid urethane is still in a visco-elastic flowing condition after elapse of certain period after spraying said liquid urethane, said upper portion having a shape corresponding to a three dimensional front surface shape of said three dimensional molded body and said lower portion having a shape corresponding to a three dimensional back surface shape of said three dimensional molded body; andtransforming said non-foamable liquid urethane into a solid body and fixing said solid body as said non-foamable liquid urethane layer on said back surface of said surface material and said surface of the plastic film or the foamable slab material, by continuing said step of integrally pressurizing and compressing for a certain period.
