Abstract:
1. A method for producing a metal container, comprising: providing a first metal and a second metal, wherein the first metal has a first melting point, wherein the second metal has a second melting point higher than the first melting point, wherein the first metal is adapted to form an engagement portion, wherein the second metal is in the form of a container having a bottom plate, wherein the first metal has a first face and a second face opposite to the first face, and wherein the bottom plate has an outer face facing the first metal; positioning the first metal on the bottom plate of the second metal, with the second face of the first metal in contact with the outer face of the bottom plate; heating the first and second metals until the first metal turns into a semi-molten state; rotating and compressing a mold onto the first face of the first metal in order to distribute the semi-molten first metal along the outer face of the second metal to form the engagement portion on the first surface of the first metal, thereby firmly adhering the first metal to the outer face of the second metal, wherein rotating and compressing the mold comprises rotating the mold in a first direction as the mold is constantly being compressed down on the first face of the first metal; removing the mold from the first metal and rotating the mold in a second direction opposite to the first direction as the mold is constantly being raised from the first metal; and engaging a heating member with the engagement portion of the first metal.
