AB  - A die casting plunger velocity inside a filling chamber of a pressure die casting machine is one of the most significant factors of a pressure die casting. This velocity determines the regime of a die cavity filling, thus influencing both inner and surface quality of castings. A selection of a correct velocity of a die cavity filling depends on such factors as an alloy type, a casting complexity, a ratio of a slot area to a casting area, etc. A static pressure test can be used to determine a permanent deformation value by which a casting quality can be considered.
