Abstract:
A method of applying a molding material which becomes malleable with heat into a designated mold while eliminating air entrapment within the molded material, the method comprising the steps of:inserting the molding material into a container, the container attached to the designated mold to allow the molding material to pass from the container into the mold when a force is applied to the molding material;applying a gradient heat to the molding material in the container to make the molding material more malleable, the gradient heat having a temperature distribution from a least heat to a greatest heat, wherein the greatest heat is applied to molding material closest to the mold and the least heat is applied to molding material furthest away from the mold; andforcing the molding material from the container into the mold while allowing air to escape along sides of the container and out a container opening furthest away from the mold.
