Abstract: Proposed is an electromagnetic vibration stirring device of semi-solid high pressure casting equipment. The electromagnetic vibration stirring device includes: a ring-shaped casing including an inner wall into which a sleeve is inserted and an outer wall spaced apart from the inner wall; and a magnetic field generating unit located between the inner wall and the outer wall of the casing, and including a plurality of electromagnets radially arranged at equal intervals around the sleeve in a circumferential direction of the sleeve, each of the electromagnets including a core and a coil surrounding the core. The magnetic field generating unit generates a magnetic field by applying a current to the electromagnets in a clockwise or counterclockwise direction, and each portion of a semi-solid molten metal is sequentially vibrated by the magnetic field along the circumferential direction of the sleeve, thereby controlling a microstructure of the molten metal.

Abstract: A method of making a test coupon using a mold is provided. The mold defines a mold cavity that comprises a first-grip-portion cavity, a second-grip-portion cavity, an intermediate-portion cavity, interconnecting the first-grip-portion cavity and the second-grip-portion cavity, and runner cavities, directly interconnecting the first-grip-portion cavity and the second-grip-portion cavity and not directly connected to the intermediate-portion cavity. The method comprises injecting feedstock material, comprising a metal powder, into the mold cavity to form a monolithic precursor test coupon in the mold cavity, wherein the monolithic precursor test coupon comprises a first grip portion, a second grip portion, an intermediate portion, and runners. The method also comprises removing the runners from the monolithic precursor test coupon.

Abstract: A high-pressure die casting apparatus including a shot sleeve extending through a first die half to a molding surface, and a plunger received in the shot sleeve is provided. The shot sleeve includes a side wall presenting a fluid passageway and a partial end wall disposed in a fixed position relative to the side wall. The partial end wall defines a wall opening adjacent the molding surface. Fluid is poured into the shot sleeve while the die apparatus is open, and the partial end wall prevents the fluid from flowing out of the shot sleeve. The plunger then presses the material into the mold cavity until only a portion of the material remains in the shot sleeve and blocks the wall opening. After the solidified material is ejected from the apparatus, the portion of material blocking the wall opening prevents lubricant from entering the shot sleeve.

Abstract: A method for die casting a metal alloy in a cavity, implementing a mold comprising an induction heater to heat the molding surfaces of the cavity. The cavity is filled with the metal alloy by injection and preheated to a nominal preheating temperature T1. The metal in the cavity is solidified. The mold is opened and the part is ejected therefrom. The molding surfaces of the cavity are heated by induction while the part is no longer in contact with said surfaces. The molding surfaces of the cavity are sprayed, the mold being opened, by a release agent. The mold is closed and the cavity is heated the temperature T1.
