A state determination device includes: a data acquirer configured to acquire data related to an industrial machine; an estimator configured to perform estimation using a learning model based on the acquired data; and a statistical data calculator configured to calculate a statistical quantity in accordance with a predetermined statistical condition and uses the calculated statistical quantity to calculate a statistical estimation value corrected from the estimation value estimated by the estimator and, accordingly, can adapt a state determination result calculated by the learning model to a change in the operation status or the like of the industrial machine.

A die-casting machine has a casting mould, a casting chamber, a casting piston arranged in an axially movable manner in the casting chamber, a melt inlet channel which leads into the casting chamber, a shut-off valve in the melt inlet channel, a melt outlet channel which leads from the casting chamber to the casting mould, and a control unit for controlling the casting piston. The control unit and the shut-off valve are configured, after completing a filling phase in a subsequent refilling phase firstly to bring the shut-off valve into an open position and to control the casting piston to move back into the casting start position, in order to supply the casting chamber with melt material via the melt inlet channel, and to control the shut-off valve into its closed position again before the casting piston has reached its casting start position by virtue of its return movement, and to control the casting piston to back-suction melt material in the melt outlet channel by virtue of the further return movement of the casting piston.

A process of reducing internal defects or enhancing mechanical properties in local regions in a solidified casting utilizes the combination effect of compression, high-intensity ultrasound, and heat on improving the local microstructure. The casting is brought to predetermined temperatures where plastic deformation in the local regions of the casting is produced under controlled conditions to close voids, breakup oxide films, and refine solidification structure.

A vacuum sensor system includes a vacuum pump, vacuum tank, solenoid valve, filters, vacuum block, sensors, and a central processing unit (CPU). The vacuum sensor system monitors the performance of a vacuum system connected to a high pressure die casting machine to ensure that the components cast in the mold or die will have a greater yield of acceptable parts. More specifically, the vacuum sensor system uses sensors to monitor and analyze the vacuum pressure at multiple locations to determine which components are clogging and causing a loss of vacuum pressure in the system. When the CPU detects an anomaly in the pressure, the CPU provides notification in one or more of the following ways: sending a command to shut down the die casting machine; visual notification on the screen of the CPU; an audible warning signal; a visual notification on a semaphore installed on the machine; and/or an electronic notification to one or more users via email, text, or other form of telecommunication.
