A preferred method of constructing a snowboard comprises co-injection molding, utilizing a skin polymer with a smooth finish for exterior portions of the snowboard and a core polymer that is lighter, structurally stronger and potentially cheaper than the skin polymer for the interior of the snowboard. A mold cavity is designed for the desired shape of the snowboard. In addition to providing for the shape of the snowboard, the mold cavity is designed to accommodate inserts for side metal edges and clips to secure such edges, if necessary, and inserts for top, flush mounted binding mounts or screw threads as well as the clips to secure such mounts. An additional set of metal components may be embedded within the top surface of the snowboard to compensate for warping away from the bottom metal edges due to the polymer shrink rate. The mold cavity must be designed to accommodate inserts for securing such metal components if such components are utilized.
