The present invention discloses a low pressure casting method and a system thereof. 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).
