Abstract: An example system includes a first stamping portion having a first surface to form a corresponding stamped surface on a metal component to be stamped, and a second stamping portion having a second surface, the second surface to oppose the first surface of the first stamping portion during stamping of the metal component. The second surface includes a metal flow receiving feature, the metal flow receiving feature including a non-flat surface to attenuate an amount of metal flowing therein during stamping of the metal component between the first stamping portion and the second stamping portion.

Abstract: Various examples provide a mold including a molding component and a supplementary component. The molding component may have a cavity, to enable a molten material to fill into the molding component to form an object. The supplementary component may include a bypass having a first opening located at a first position of the molding component and a second opening located at a second position of the molding component. The molten material may flow from the first position to the second position via the molding component, flow from the first opening to the second opening via the bypass and fill into the second position of the molding component through the second opening.
