ABSTRACT:
A dynamic variation of a cavity pressure (P, Vac) in a die cavity (17) defined between a stationary die (3) and a movable die (7) is supervised during an injection of molten metal (M) by a pressure supervisory system (27, 29, 43, 45, 53, 75, 83, 95) that includes a pressure detection path (27,37) communicating with the die cavity, a pressure sensor (73) for detecting the cavity pressure through the pressure detection path and a processor (75) for processing detection data of the cavity pressure, and the stationary die (3) is formed with a pressure detection port (27) that constitutes part of the pressure detection path.
