Abstract
The method for producing a skin material includes heat-pressing a raw material using an embossing die to obtain a skin material having a concave part formed on a front surface side and a flat back surface. The raw material is heat-pressed between the embossing die and an elastic mat to form, as the concave part, at least one of a plurality of concave parts for intensity display having different depths of a bottom and a concave part for gradation display in which the depth of the bottom gradually changes.
Claims12
A method for producing a skin material, the method comprising:
- heat-pressing a raw material using an embossing die to obtain the skin material having a concave part formed on a front surface side of the raw material and a flat back surface of the raw material,
- wherein the raw material is heat-pressed between the embossing die and an elastic mat to form, as the concave part that includes a bottom, at least one of:
- a plurality of concave parts for intensity display having different depths of the bottom, and
- a concave part for gradation display in which a depth of the bottom gradually changes, and
- wherein, during the heat-pressing, an end of the embossing die that contacts the bottom of at least one of the concave part is disposed closer to the flat back surface than to a surface height of the elastic mat in a natural state.
