Abstract

PURPOSE:To manufacture a molded material with a marbly pattern having a vignettig effect by a method in which a different color material is injected into a softened synthetic resin against the flow of the resin and mixed with the resin, and the resin is introduced into molds. CONSTITUTION:A softened synthetic resin is pushed into a mixing chamber 4 while being stirred by a pressure feeder 2, and at the same time different color materials are injected into the pressure feeder 2 side from holes 8 and 9 at the inside end 5 of the holding ring 4 of a mandrel 3. And, they are mixed together in the mixing chamber 14 and then sent into a mold body 10. Thus, a molding with a marbly pattern having a vignetting effect in which light color portions 12 and 13 are gradually changed in relation to thick color portions can be obtained.
