Abstract: Methods for casting high strength, high ductility lightweight metal components are provided. The casting may be die-casting. A molten lightweight metal alloy is introduced into a cavity of a mold. The molten lightweight metal alloy is solidified and then a solid component is removed from the mold. The solid component is designed to have a thin wall. For example, the solid component has at least one dimension of less than or equal to about 2 mm. In this way, a chill zone microstructure is formed that extends across the at least one dimension of the solid lightweight metal alloy component. The solid component thus may be substantially free of dendritic microstructure formation, enabling more extensive alloy chemistries than previously possible during casting. Such methods may be used to form high strength, high ductility, and lightweight metal alloy vehicle components.

Abstract: A method for preparing semisolid slurry. The method is achieved using a device for preparing semisolid slurry. The device includes a slurry vessel and a mechanical stirring rod. The mechanical stirring rod includes a first end and a second end extending into the slurry vessel. The method includes: S1. putting a molten alloy having a first preset temperature into the slurry vessel; S2. cooling the molten alloy to a second preset temperature, positioning the second end of the mechanical stirring rod to be 5-25 mm higher than the bottom wall of the slurry vessel, rotating the mechanical stirring rod and injecting a cooling medium into the mechanical stirring rod; and S3: allowing the temperature of the molten alloy to be 10-90 degrees centigrade lower than the liquidus temperature of the molten alloy, stopping stirring and cooling, to yield a semisolid slurry.

Abstract: A mold (1) for injection-compression molding includes a punch (2) and a matrix (3) suitable to close on the punch (2) to delimit with this an injection chamber (10) to contain the material to be injected. The matrix (3) and punch (2) are axially movable between them with respect to an axial direction (Y-Y) of opening/closing of the mold (1). The mold has a perimetral ring (4) slidingly associated to the punch (2) or the matrix (3), along the axial direction (Y-Y), suitable to define, together with the matrix (3) and the punch (2), the profile of the injection chamber (10). The perimetral ring (4) includes an interface profile (43) engaging with the matrix (3) or with the punch (2), equipped with a particular geometry generating in the closing phase of the mold (1), a compression force of the ring (4) towards the inside of the mold (1).

Abstract: A die casting machine includes a clamping device 7 which opens and closes and clamps a pair of die halves, an injection apparatus which performs injection to the pair of die halves by making a plunger move forward in a sleeve communicated with a space between the pair of die halves, and a control device which controls the clamping device and injection apparatus. The control device includes an injection control part and press-use clamping control part. The injection control part controls the injection apparatus so as to start the injection in a state where the pair of die halves face each other through a gap. The press-use clamping control part controls the clamping device so that the die contact and clamping are carried out after the start of injection. Further, the injection control part performs control for decelerating the plunger before the plunger stops.
