  • Patent number: 6843946
    Abstract: A mold for forming wood flakes into a molded wood flake part including a top mold die and a bottom mold die. The top mold die includes a punch for forming a hole in the part, and the bottom mold die includes a punch receiving aperture. The punch includes a tapered upper portion and a cylindrical lower portion for forming the hole in molded parts of varying thicknesses. The punch includes a tapered upper section defining an upper opening of a first radius in a top surface of the molded part and a cylindrical lower section defining an opening of a second radius in a bottom surface of the molded part. The cylindrical lower portion is sufficiently long that the bottom opening in the hole in each part formed will have the same second radius.
