Abstract: A type of relief engraved doorplate, comprising an inside plate that is composed of a first Bakelite layer and a second Bakelite layer, said first Bakelite layer and second Bakelite layer being composed of coarse wood dust and fine wood powder respectively, the second Bakelite layer enveloping the exterior of the first Bakelite layer before they are subjected to heated compression molding to obtain the relief engraved pattern on the top and bottom panels of the inside plate; and, at least one pair of outside decorative plates, including at least a layer of thin wood plate and a layer of water-resistant paper, the water-resistant paper being glued onto the thin wood plate and put in a compression mold with a pattern that is opposite to that of the inside plate, to obtain a depressed pattern on one side of the outside decorative plate, which is opposite to the relief engraved pattern on the inside plate, and then it is fitted to the top and bottom panels of the inside plate and subjected to compression molding process to obtain a relief engraved doorplate that has a tightly knit structure and tenacity to resist water and fire.
