Abstract
Disclosed is a metal molding process, including passing, through a conduit passageway, a volume of molten metal located downstream of a passageway blockage formable in the conduit passageway. Also disclosed is a molded article having a body made by a metal molding process, including passing, through a conduit passageway, a volume of molten metal located downstream of a passageway blockage formable in the conduit passageway.
Claims7
A metal molding process, comprising:
- supplying a molten metal to a metal hot runner assembly (401) from a metal injection unit (403B) via a nozzle (403C);
- supplying the molten metal from a metal hot runner assembly (401) to a mold cavity (412) of a metal molding system (403A), the metal hot runner assembly (401) includes a metal molding conduit assembly (400) with a conduit passageway (402), the conduit passageway (402) defined by a conduit body member (408) that forms a central passageway configured to receive molten metal from the metal injection unit (403B) and a plurality of drops (410A, 410B) leading to the mold cavity (412);
- forming a metal plug (406) in the central passageway configured to receive molten metal from the metal injection unit (403B);
- and
- catching the metal plug (406) in a plug catcher (430) so that the metal plug (406) does not disrupt flow of molten metal into the plurality of drops (410A, 410B) leading to the mold cavity (412).
