Molten metal filter device for casting vehicle components

A molten metal filter system, comprising:

• a holding tank operable to receive a molten metal;
• a filter device comprising a chamber, an inlet channel operable to receive the molten metal from the holding tank and convey a flow of molten metal into the chamber, and an outlet channel operable to convey the flow of molten metal out of the chamber and back into the holding tank;
• a pump operable to move the molten metal from the holding tank through the inlet channel;
• and
• a plurality of removeable filters disposed in series within the inlet channel, wherein the plurality of removable filters are operable to remove inclusions above a determined diameter size from the molten metal;
• wherein at least one of plurality of removeable filters includes a form factor occupying a cross-section of the inlet channel perpendicular to a direction of the flow of molten metal through the inlet channel
• wherein the filter device further comprises a heat conductive partition wall disposed between the inlet channel and the outlet channel;
• and
• wherein the outlet channel is operable to convey the flow of molten metal in a direction counter-current to the direction of the flow of molten metal through the inlet channel.

A continuous flow molten metal filter system, comprising:

• a filter device operable to filter a molten casting alloy to produce a filtered molten casting alloy;
• and
• a casting device operable to receive the filtered molten casting alloy to form a solidified casting;
• wherein the filter device comprises:
• an inlet channel;
• a chamber downstream of the inlet channel;
• and
• an outlet channel downstream of the inlet channel;
• a heat conductive partition wall disposed between the inlet channel and the outlet channel;
• and
• at least one removable filter disposed in the inlet channel;
• wherein the at least one removeable filter includes a form factor occupying a cross-section of the inlet channel perpendicular to a direction of a flow of molten metal through the inlet channel;
• and
• wherein the outlet channel is operable to convey the flow of molten metal in a direction counter-current to the direction of the flow of molten metal through the inlet channel.
