摘要： In a pressure-casting method and apparatus, wherein a metal melt is fed in a mold cavity and then an oscillating squeeze pressure is applied to the melt by a squeezing plunger of a hydraulic cylinder moving with an oscillating stroke varying to compensate for shrinkage of the melt while being solidified, the hydraulic cylinder is feedback-controlled, using a control unit including a detector for detecting information on an actual squeeze pressure, so that a pressure converted from the actual oscillating squeeze pressure to have a mean value of zero copies a desired alternately positive and negative impulsive pressure pattern or locus representing a pressure oscillated to have a mean value of zero with a given amplitude and frequency versus an elapse of time.
