Manufacture of preformed module of thermoformed footwear sole uses digital model based on morphology of foot, interior shape of footwear and use

摘要

A procedure for manufacturing a preformed module (1) for a thermoformed sole, consists of preparing a digital model of the module's volume based on the morphology of the foot, the inner shape of the footwear and its intended use, and making the preformed module from a thermoformable material based on the volume of the digital model. The procedure for manufacturing a preformed module (1) for a thermoformed sole consists of preparing a digital model of the module's volume based on the morphology of the foot, the inner shape of the footwear and its intended use, and making the preformed module from a thermoformable material based on the volume of the digital model. The module can be made by cutting, injection molding or machining, using a flat blank (3) with two parallel faces (4, 4') and having an outer edge (5) perpendicular to the two faces. The blank can be machined partly automatically, using procedures such as milling, routing, grinding, or cutting by laser or water jet.
