moulage sans châssis

OBS: flask casting / moulage en châssis.

CONT: In flaskless molding (whether vertical or horizontal) instead of using ""tight"" individual flasks for each mold produced, the master flask is contained as an integral unit of the totally mechanized mold producing system. Once the mold has been stripped from the integral mold producing unit, it is held against the other half of the mold with enough pressure to allow pouring of the metal.
CONT: The new system is flaskless moulding thus eliminating the inherent problems associated with conventional moulding boxes.
