Abstract:
A method for producing a molded resin product with simulated wood grain patterns on an exterior surface thereof, comprising the steps of:supplying a first molten resin into a mold cell to form a resin layer with said exterior surface; making a plurality of grooves through said resin layer so as to reach said exterior surface by moving a plurality of pillars through said resin layer while in contact with an inside surface of said mold cell before said molten resin solidifies; filling up said grooves with a second molten resin such that said exterior surface exhibits simulated wood grain patterns; solidifying said first resin and said second resin; and moving said pillars at an irregular speed to thereby form simulated wood grain patterns having irregular widths on the exterior surface of the molded resin product.
