Abstract

An article having non-planar portions, such as a pallet having a substantially flat deck member and a plurality of hollow leg members projecting integrally from the deck member, is molded as a one-piece unit from a loosely-felted, layered mat formed from a mixture of a resinous particle board binder and flake-like wood particles. The wood flakes have an average length of about 11/4 to about 6 inches, preferably about 2 to about 3 inches, an average thickness of about 0.005 to about 0.075 inch, preferably about 0.015 to about 0.025 inch, and an average width of 3 inches or less and no greater than the average length. Each layer of wood flakes in the mat lie substantially flat on a plane generally parallel to the major plane thereof and are randomly oriented to each other. The mat is placed between the male and female dies of a mold or press and compressed therein to substantially the desired shape under temperature and pressure conditions sufficient to bond the flakes together.
