Abstract (en)
[origin: WO2018232201A1] A die casting furnace system includes a die casting holding furnace unit defining a cavity for holding a molten metal. A dosing unit is disposed within the cavity and defines a dosing area disposed in fluid communication with the cavity for receiving the molten material during a pressurization of the cavity. The cavity of said die casting holding furnace unit has a first storage capacity and the dosing area of said dosing unit has a second storage capacity being less than the first storage capacity. An ultrasonic unit is operably coupled with the finitely sized dosing area and is configured to introduce vibration into the received molten material for facilitating the removal of gases from the received molten material. The treatment of the finitely sized dosing area with the ultrasonic unit leads to improved metal cleanliness and accuracy that is not achievable with prior art systems.
