Date Dec. 14, 1995In order to improve the compression operation and to produce better products with thin-walled castings, the invention calls for the compression operation to be divided into three phases and controlled by high-dynamic continuous-operation valves which have very short switching times and are actuated by a control device. Fitted in the hot-chamber die-casting machine for this purpose is a metal sensor which is disposed in a die relief leading from the rising bore in the casting container into the mould.
