A heel cap manufacturing method includes the steps of: a) preparing a multilayer composite material; b) performing the first time of molding by thermal pressing to the multilayer composite material by a thermal pressing device to obtain a thermal pressed semi-product; c) taking out the thermal pressed semi-product from the thermal pressing device and fixing it to a heel cap mold; d) performing the second time of molding by cold pressing to the thermal pressed semi-product together with the heel cap mold in a cooling device to obtain a cooled semi-product; and e) demolding and rewarming the cooled semi-product to obtain a finished heel cap. The present invention uses the processing manner of molding twice by cold and thermal pressing to manufacture the structurally more complex heel cap, effectively lowering difficulty of the manufacturing process and raising production efficiency. A heel cap manufacturing equipment is also provided.

The present invention relates to the field of shoe material technology, more particularly to a type of elastic heel and its manufacturing process, including the following steps: (1) material configuration: selecting a material from foam rubber, elastic PU, foamed latex, foam sponge, PVC foam and EVA foam required for configuration upon the need; (2) mold preparation: preparing the heel mold consisting of upper and lower platens, among which the inside surface of the lower platen is a concave while the inside surface of the upper platen is a convex, each having the same shape as the heel inner and outer surface, and there are venting holes on the upper platen, and on the inside surface of the lower platen lays elastic fabric; (3) placing the solid foaming material of the Step (1) in the mold and closing the mold halves to proceed foam forming; (4) opening the mold for demolding.

A two-part method for dye-sublimation printing a decorative design on a moldable orthotic substrate comprising a first digital printing step of printing a computer image file of a decorative design on a digital transfer paper substrate using dye-sublimation CMYK inks, and a second dye-sublimation printing step comprising the steps of heating an oven to a first temperature, placing a moldable orthotic substrate inside the oven, heating the moldable orthotic substrate to a second temperature, positioning the digital transfer paper substrate on the moldable orthotic substrate with the decorative design down and in contact with the moldable orthotic substrate, and sublimating the at least one color of dye-sublimation CMYK inks from the digital transfer paper substrate to the moldable orthotic substrate. A custom orthotic product may be manufactured by wrapping the dye-sublimation printed moldable orthotic substrate around an orthotic mold and applying a vacuum.
