In mfg. process for metallic components using the principles of squeeze casting, approx. the required amount of liq. metal is put into the mould form and displaced by an upper die, and a flat edge sealing flange pref. made of copper or a copper alloy, is placed between the mould halves around the mould shape above the bath level initially. As the upper die is lowered the level of the liquid metal increases until it fills the increased headspace created by the sealing ring. After solidification pressure is applied to form the metal simultaneously expanding the seal.
