Abstract
Cast polyurethane parts for shoes or other items may be formed in an automated fashion. A dispensing mechanism may dispense a predetermined amount of a liquid phase polyurethane mixture onto a flat surface face of a mold. A dispersal mechanism may distribute the liquid phase polyurethane mixture over the flat surface face of the mold to fill at least one cavity in the form. A vacuum may be applied to remove air bubbles from the liquid phase polyurethane mixture. Excess liquid phase polyurethane mixture may be removed from the flat surface face of the mold using a flexible blade that contacts and moves across the flat surface face. One or more conveyance mechanism may transport molds through the desired stages of a system and/or method in accordance with the present invention.
