    摘要: A die casting system includes a die, a shot tube, a shot tube plunger and a melting unit. The die includes a plurality of die components that define a die cavity. The shot tube is in fluid communication with the die cavity. A shot tube plunger is moveable within the shot tube to communicate a charge of material into the die cavity. The melting unit is positioned relative to the die and includes a bottom portion having an opening for selectively releasing a charge of material through the bottom portion.

    摘要: Systems and methods for reducing the potential for riser backfilling during investment casting are provided. In this regard, a representative method for performing investment casting includes: providing a mold having an opening communicating with an interior, the interior having a part cavity and a riser; providing an insert; and using the insert to form a physical barrier to reduce a potential for molten metal to backfill into the riser while the molten metal is introduced into the interior of the mold via the opening.
