Abstract
PURPOSE: To manufacture a foamed article having shade patterns originated from density difference, by pouring a colored foamable synthetic resin into a mold in the manner to give non-uniform surface density after foaming.
CONSTITUTION: For example, a silicone rubber mold 7 is set in a lower mold 6, and colored foamable urethane 11 is poured to the rubber mold 7 in stipes through a number of orifices 10 of a fan-shaped nozzle 9 placed above the mold. The mold is closed with an upper mold 12, and the urethane composition is foamed to afford a foamed urethane plate 11' having stripewise density difference. The high-density part (a) and the low-density part (b) correspond to the dense and the light shade, respectively. Similary, a dense part (a) corresponding to the insufficient foaming can be obtained by forming a recess 8 to the rubber mold 7.
