Abstract
PURPOSE: To obtain the resin sheet having smoothly curved convex parts, by arranging the freely expandable and contractable release sheet to the back of the mold plate provided with the through holes, foaming the foamable resin filled in its back side and protruding the foam convex like from the through holes.
CONSTITUTION: Foamable resin 4 is poured in the upper face opened silicone molding bath 6 and covered by a releasing sheet 3, then, after the planar mold plate 2 drilled with many through holes 1 is fixed to the upper face opening of the silicone rubber bath 6, the foamable resin is foamed. Expansion of foamed resin 4 pushes up the releasing sheet and the foam protrudes from the through holes, the foamed resin sheet shaping the smoothly curved convex part 5 is obtained.
