Abstract (en)
[origin: EP0956916A1] An overwhelming proportion of the melt volume required for filling of the mold cavity is forced into the latter at a maximum velocity. The melt column in the riser pipe (7, 8) is sheared off, and the residual melt volume between the shearing-off point and the mold inlet (11) is forced into the mold cavity at a velocity with a negative gradient. An Independent claim is also included for an apparatus for carrying out the low pressure casting method.
