Said system comprises at least one casting unit (1); at least two sensors (2), each for detecting at least one process parameter in the casting unit (1) during the casting process; at least one intermediate control unit (3) which is connected with the sensors (2) and the casting unit (1) for receiving the process parameters detected by the sensors (2) and controlling operation of the casting unit (1); at least one main control unit (4) for comparing the production parameters detected by the sensors (2) during the casting process with the acceptable maximum and minimum values in the bill of materials, so that quality of the produced part is determined. Said method comprises the steps of initiating the part production process in a casting unit (1); receiving at least two different process parameters by means of at least two sensors (2) during the part production in the casting unit (1); sending the received process parameters to at least one intermediate control unit (3); transmitting the process parameters, which have been sent to the intermediate control unit (3), to at least one main control unit (4); detecting quality of the produced part by comparing the process parameters in at least one bill of materials in the main control unit (4), which contains maximum and minimum acceptable values of at least two process parameters for the casting process, with the process parameters transmitted from the intermediate control unit (3).

摘要： This invention provides a casting method for a casting of high quality and a press for casting such a casting by controlling the speed of the press that presses a mold in the pressing process, after a upper mold overlaps a lower mold.
The invention provides a casting method for a casting and the press for that casting method. They use the lower mold having a concave portion that has a shape of a casting, and the upper mold having a convex portion that has a shape of the casting, which convex portion forms a cavity to produce the casting by overlapping the lower mold.
A casting method to produce a casting and a press used for the casting method, using a mold which forms a cavity in a shape of a casting, so as to produce a casting by overlapping a lower mold with an upper mold, which molds are molded by a molding method, said casting method comprises steps of:
pouring into the lower mold a quantity of molten metal required to produce a casting;
lowering the upper mold at a predetermined first speed until the upper mold reaches a predetermined position just before the upper mold starts contacting a surface of the molten metal;
lowering the upper mold at a predetermined second speed after the upper mold is further lowered beyond the predetermined position ;
detecting and obtaining information on the status of the upper mold which overlaps the lower mold; and,
stopping the lowering of the upper mold when detecting the information on the status of the upper mold that shows that the predetermined conditions are met.

摘要： The present invention relates to a method for casting ferrous or heavy metal articles in vertically parted sand moulds (1) of a mould string plant through an inlet (15) below or aside the mould cavity (5), by filling the moulds with molten metal by counter-gravity delivery using a source of pressure. The pressure is varied during the filling procedure to steer the flow speed and impact on the mould (1) of the molten metal upon complete filling of the mould cavity (5) is reduced.

摘要： When casting e.g. aluminium alloy in a mould (2), that may be one of a string of moulds extending at right angles to the plane of the drawing, the pressure used for filling the mould (2) against gravity by means of a pressurizing device (4) is controlled according to a predetermined pressure/time programme having previously been read into a control unit (22), e.g. a digital computer, at least one of a number of sensors sensing pressure (8), levels (9, 10) and full level (11) being used to supply inputs to the control unit (22). Sensors are chosen according to need for each particular casting programme.

摘要： In a mould (1) with vertical parting surface, each mould cavity (2, 2') is connected through a wide throat with its own after-feeding reservoir (3, 11). When the mould (1) has been poured, a gas pressure is applied through a duct (15, 19) to a metal surface in the after-feeding reservoir (3, 11). This gas pressure is not allowed to exceed the metallostatic pressure in the mould at the surface, at which the pressure is applied, until the metal in the ingate (4) has solidified or the ingate has been blocked in some other way. At the location where the duct (15, 19) opens into the after-feeding reservoir, it is covered by an element (16, 20) that is impermeable for the metal having been poured but permeable for the pressurized gas. When the metal in the ingate (4) has solidified or the ingate has been blocked in some other way, the gas pressure may be increased.
