Abstract:
A metal casting chamber apparatus is fabricated from fire-resistant materials and is fully enclosed and externally ventilated to safely contain the molten metal and extract fumes released during casting operations. The metal casting chamber apparatus may additionally feature a smart chamber monitoring system capable of wirelessly transmitting one or more monitored parameters of the process and/or visual data to a mobile device such as smartphone, and to allow wireless control of one or more parameters of the metal casting process.

Abstract:
A method of moulding a settable material includes the steps of: (i) providing a first mould or mould cavity; (ii) providing an outlet from which a settable material is discharged; (iii) aligning the first mould or mould cavity with the outlet; (iv) discharging settable material from the outlet into the first mould or mould cavity; (v) providing a second mould or mould cavity; (vi) displacing the first mould or mould cavity away from the outlet; (vii) aligning the second mould or mould cavity with: (a) the outlet; and (b) the first mould or mould cavity such that the second mould or mould cavity is in fluid communication with the first mould or mould cavity; (viii) discharging settable material from the outlet into the second mould or mould cavity; (ix) permitting a portion of the settable material discharged into the second mould or mould cavity to flow from within the second mould or mould cavity to within the first mould or mould cavity; (x) further displacing the first mould or mould cavity and the second mould or mould cavity away from the outlet; (xii) permitting: (a) the settable material in the first mould or mould cavity to set into a first moulded article; and (b) the settable material in the second mould or mould cavity to set into a second moulded article; and (xiii) severing the first moulded article from the second moulded article.
Abstract:
The invention relates to a method for direct casting of cast components by layer-wise generation of composite molds, wherein the composite molds are generated as monolithic elements and simultaneously with their respective cores in an assembled form. The system for layer-wise generation of three- dimensional models from the powdered material in a removable container (1) with a movable bottom (2), which is separated from the device for lifting and lowering (4) the movable bottom, which is built into the system for layer- wise generation of three-dimensional models. The generation of the molds is done by application of layers of powdered material and binding of the particles of each layer through a binder, added selectively according to a program/pattern only in the volumes, where the solid body of the model is being generated. This procedure is subsequently repeated until the entire volume is constructed, allowing direct casting in the resulting molds without removing them from the container (1), in which they are generated, after removing the unnecessary powdered material from their working cavities.

Abstract:
The invention provides a method, of indexing moulds (2 1 , 2 2 ) using; a flaskless moulding Machine (10) for forming moulds (2,2 1 , 2 2 ) and a mould conveyor (20) for carrying, and advancing a mould string (4) produced from a plurality of the moulds (2 1 , 2 2 ) received by the mould conveyor (20) from the flaskless moulding machine (10). The method comprises the first step of: (i) forming one or more moulds (2 1 , 2 2 ) one at a time using the flaskless moulding machine (10), each of the one or more moulds (2 1 , 2 2 ) being added to the mould string (4) while the mould string (4) is stationary by being brought Into contact with the mould string (4), subsequently to being produced by the flaskless moulding machine (10). Once the one or more moulds (2 1 , 2 2 ) has been produced and added to the mould string (4), the method continues in step (ii) by advancing the mould siring (4), in a single motion, away from the flaskless moulding machine (10) a distance corresponding to the sum of the thicknesses of the one or more moulds using: the mould: conveyor (20) wherein the flaskless moulding machine (10) assists the mould conveyor (20) in advancing the mould string (4) during a first part of the distance, and wherein the mould conveyor (20) advances the mould string (4) a second part of the distance, corresponding to the remainder of the distance, without assistance from the flaskless moulding machine (10), The single motion is continuous, A system for indexing moulds is also provided.
