A method for producing a metal container includes providing first and second metals. The first metal has a first melting point, and the second metal has a second melting point higher than the first melting point. The first metal is adapted to form an engagement portion. The second metal is in the form of a container having a bottom plate. The first metal has first and second faces. The bottom plate has an outer face. The method further includes positioning the first metal on the bottom plate and heating the first and second metals until the first metal turns into a semi-molten state. The method further includes rotating and compressing a mold onto the first face in order to distribute the semi-molten first metal along the outer face to form the engagement portion. The method further includes removing the mold and engaging a heating member with the engagement portion.
