METHOD FOR COATING A DIE SURFACE WITH RELEASE AGENT |
摘要 |
A method for coating a die surface with a foamed release agent is disclosed. The release agent is foamed outside a die and then is supplied to a die cavity. Alternatively, liquid release agent is supplied to the die cavity and then is foamed inside the die. Excess foamed release agent is removed from the die before molten metal is supplied to the cavity. Alternatively, the foamed release agent is left in the cavity, and molten metal is supplied to the cavity. The release agent is foamed through mechanical agitation, bubbling, or by gas released from the release agent when heated. 23
