A casting apparatus for producing castings using molds each having a sprue, comprising a mold-conveying means for conveying molds each containing a melt poured through the sprue; nozzles each having a gas-introducing opening attachable to and detachable from the sprue; nozzle-attaching/detaching means each moving each nozzle to attach and detach the gas-introducing opening to and from the sprue; moving means for moving the nozzle-attaching/detaching means, such that the nozzle-attaching/detaching means moves following a mold conveyed by the mold-conveying means, while keeping the connection of the gas-introducing opening to the sprue by the nozzle-attaching/detaching means; and a gas supply means connected to each nozzle for supplying a gas to the gas-introducing opening.

A method of manufacturing an aerodynamic element with an edge is provided. The method includes producing the aerodynamic element with an initial condition, cooling the aerodynamic element, generating a predefined number of data points sufficient to characterize contours of the edge and comparing the data points to a nominal condition to derive transformation parameters applicable to cutting toolpaths to adapt the cutting toolpaths to the initial condition.

To provide a system for producing steel castings that is simple and suitable to continuously produce many small steel castings. A system 1 comprises multiple furnaces 10 that are aligned and hold molten metal for cast steel, a pouring machine 20 that has a ladle 30 that receives the molten metal from the furnaces, wherein the pouring machine travels in parallel to a line of the furnaces and pours the molten metal into a mold 70 by tilting the ladle, a line 60 for conveying the molds that intermittently conveys molds that are aligned in parallel to a direction in which the pouring machine travels, wherein the line is located on the opposite side of the furnaces across the pouring machine, and a temperature sensor 38 that measures a temperature of the molten metal so as to generate an alarm if the temperature is low.

A casting system is provided with at least two low-pressure casting furnaces. Each of the at least two low-pressure casting furnaces is adapted to be connected in fluid communication with a mold. At least one controller is in cooperation with the at least two low-pressure casting furnaces to collectively operate the low-pressure casting furnaces to cast a material into the mold.

A pouring machine is provided to constantly maintain the level of the surface of melt without a leak, or the like, to maintain a necessary and sufficient pouring rate. The pouring machine (1) that pours molten metal from a container into molds in a line comprises a bogie (10) that travels along the molds; a mechanism (20) for moving the container back and forth that moves the container perpendicularly to the direction that the bogie travels; a mechanism (40) for tilting the container that tilts the container; a weight detector (50) that detects the weight of molten metal in the container; a surface-of-melt detector (60) that detects the level at a pouring cup (110) of a mold (100); and a controller (70) that controls the angle of the tilt of the container by using the detected level and the detected weight.

A metal casting installation is provided that includes a robot configured for carrying out the operations of handing a new ladle shroud to a manipulator of the ladle located at the loading station, and coupling a driving device to the ladle slide gate each manipulator is fixed relative to the corresponding first or second ladle such as to move together with the corresponding first or second ladle between the loading station and the casting station.

A machine for forming metal bars, in particular for producing ingots made of precious metal such as gold, silver, precious alloys, as well as other pure metals or different alloys, in the form of solid metal powder, grits or swarf of various sizes, having an ingot mold and a cover for closing the ingot mold when filled, the ingot mold has a dimension in height such that the cover passes from a first position to a second position when the volume occupied by the mass of metal that fills the ingot mold reduces gradually up to one third of the initial solid volume. In the first position the cover rests on the metal that fills the ingot mold and remains raised with respect to an abutting edge of the ingot mold, in such a manner that the bottom of the cover compresses and thus uniformly compacts the powders, the grits or the swarf so that, during the melting step, in the second position, the cover lowers progressively as the metal melts, until it rests on the abutting edge of the ingot mold, thus hermetically closing the ingot mold.
