  • Aluminum ingot casting machine
    Patent number: 7637304
    Abstract: An aluminum ingot casting machine having a source of molten metal, a rotatable annular ring, carrying ingot casting moulds and a drive member for indexing the moulds. The machine includes a vacuum demoulder having a vacuum seal arrangement having a sealing element having a flexible core which can deform to form a vacuum seal against an ingot and a flexible abrasion resistant outer layer on the core, and retaining elements located on a lower face of the vacuum lifting head for releasably retaining the sealing element onto the lifting head. The vacuum seal has a flexible ring shaped body, being rounded in cross section, having a fibre cord core and an abrasion resistant flexible sheathing surrounding the core.
