Abstract

See full text

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.
