Abstract
The die casting machine includes a trough containing a supply of molten metal and a feed tube extending into the supply of molten metal in the trough. A flow of molten metal is maintained in the trough past the feed tube independent of the transfer of molten metal through the feed tube. The die casting machine further includes a filtering system.
