Patent ID: 8414811

Claim:
A method of manufacturing a heat moldable insole comprising an arch portion and a heel portion each having a harder thermoplastic elastomer, and, a non-arch portion having a softer thermoplastic elastomer comprising the steps of: creating a mold with a plurality of cavities outlining a human foot utilizing a rotary, two shot, tool indexing means wherein the molding is either loaded by hand or manual means or loaded by automatic or robotic means, said mold in a closed position; loading the first shot of a thermoplastic resin into a first cavity in the mold while said mold is in a first position facilitating loading of thermoplastic resin into said first cavity, at a first time interval; rotating the mold either by hand or automatically, to a second position and loading a second shot of a thermoplastic resin into a second cavity while said mold is in a second position facilitating loading of the thermoplastic resin into said second cavity, at a second time interval; bonding the first and second shot thermoplastic resins mechanically and/or chemically to one another and opening the mold to remove the heat moldable insole.
