摘要：
A method of producing molded wood flake or strand three-dimensionally curved products using draft angles of 10 degrees or larger with little or no blistering or wood flake springback from over densification. A loosely felted mat of wood flakes is placed between top and bottom molds which slidably engage one another at pinch points to pinch and sometimes remove excess flashing/pinch trim.
