Apparatus and method for manufacturing die-cast product
Fluid pressure of a first fluid chamber of a driving means, which acts as a back pressure, is monitored by a monitoring means when a core pin is driven by the driving means in an inserting direction before injection of a molten material into a cavity of a die arrangement. When the monitored fluid pressure of the first fluid chamber exhibits abnormal behavior that is different from normal behavior observed during a normal period, the monitoring means controls the driving means to stop the driving of the core pin in the inserting direction.
