A process of forming an erosion, oxidation, and wear resistant shot chamber, either a gooseneck or a shot sleeve, is provided. The process utilizes a self-healing erosive wear resistant coating on a liner of refractory metal to serve as the working surfaces of a shot chamber. Such a shot chamber is expected to have an improved service life for die casting of corrosive metals and alloys, including hot chamber die casting of aluminum alloys. An improved hot dipping process using stirring in the molten metal bath is also disclosed.

A mould for injection moulding is provided which has a mould body having a plurality of boundary surfaces, the plurality of boundary surfaces having at least one moulding surface configured to delimit a mould cavity. The mould body is made by additive manufacturing. The mould body has a functional domain portion on which the plurality of boundary surfaces and the moulding surface are formed, the functional domain portion being composed of a solid, continuous material structure covering a fraction of the mould body, and an application domain portion which is the complement of the functional domain portion in the mould body, the application domain portion being composed of a three-dimensional material lattice structure having an ordered repetition of unit cells including a periodic minimal surface. The at least one geometrical parameter of the periodic minimal surface is tuned locally to form unit cells with different densities of material.

A molding system for a low-pressure light alloy casting plant, extending in height along a main axis, has a mold having a lower half-mold and an upper half-mold. The molding system has a first lower fixed plate on which the lower half-mold is housed, a movable plate on which the upper half-mold is housed, a second upper fixed plate positioned at the top of the movable plate, a movement group for moving the movable plate along the main axis, having an electric drive motor and transmission members operatively connected to the electric drive motor and to the movable plate, a casting ejection group having an electric ejector motor and ejection members movable by the electric ejector motor in an ejection position in which the casting is detached from the upper half-mold, and a command unit controlling operation of the electric drive motor and of the electric ejector motor.

A method of manufacturing a joint flange using a thickness-increased, machined pipe is provided. The method includes a pipe cutting operation in which a pipe is cut to a predetermined length, a flange forming operation in which a flange having a mounting hole for installing the pipe is formed by die casting, a bump-forming operation in which a thickness-increased part, which is formed by increasing a thickness of one end of the pipe, is bumped to form a first bead locked to the flange, a machining operation in which a circumference of the thickness-increased part is machined to form a sealing groove having an O-ring installed, and a fixing operation in which the pipe is inserted in the mounting hole of the flange and the other end of the pipe is pressed to form a second bead so that the pipe is pressed to a lower end of the flange.

A molding tool made of carbon or graphite, namely a casting mold or a casting core for the processing of molten metal or to a molding tool for the processing of molten glass, such as for example a blow mold and a method for producing the molding tool.

An aluminum casting method is for pouring an aluminum molten metal (12) pumped up by an electromagnetic pump (20) into a die (50). A thickness of a powder demolding agent applied to the die (50) is set to be thinner than that of a demolding agent for a gravity die casting. A temperature of the die immediately before the molten metal is poured is controlled so as to fall within a range that is between 110° C. to 250° C. A temperature of the molten metal when poured is controlled to be a value obtained by adding 20° C. to 55° C. to a liquidus-line temperature of the aluminum.

A mold degassing device which can reduce the likelihood of particulates entering between a valve stem and an insertion hole is provided. The mold degassing device (10, 40, 50) includes an inflow passage (11, 41, 51), a discharge passage (12), a communication passage (13), a valve device (30) for opening and closing the communication passage (13), a gas-flow adjusting part to adjust a gas flow. A wall surface forming the communication passage (13) is provided with an insertion hole (32d) through which a valve stem (31) of the valve device (30) is inserted. The gas-flow adjusting part is positioned closer to the inflow passage (11, 41, 51) than the insertion hole (32d) and, when gas is discharged, generates a gas flow directed rotationally about an axis (C).
