A method and apparatus for producing solid alloy components from its liquid state are provided. The molten alloy is rapidly cooled using a chill to temperatures below the thermosolutal transition temperature of the alloy. Finite-amplitude acoustic vibration is applied on the chill to shake off dendrites that form on the chill surface, to stir the slurry containing the fragments of dendrites, and to shake off slurry material that sticks on the surface of the chill as the chill is separating from the slurry. The slurry is then immediately poured into a chamber of a forming machine or a mold cavity shaped into solid components.

A method for producing a vehicle wheel from a light metal material is disclosed herein. The light metal material is introduced in liquid form into a mold cavity of a casting mold and pressurized casting is then used to produce the vehicle wheel. The casting mold is temperature-controlled, where different regions of the casting mold are maintained at different temperatures. An apparatus that includes the disclosed casting mold is also described herein.

An production apparatus of a semi-solidified metal has a vessel and a cooling device. The vessel into which a liquid-state metal material M is poured has a hollow member which is opened in up and down directions, and a bottom member which can close the lower opening of the hollow member and can be separated from the hollow member. The cooling device can cool the bottom member more than the hollow member.

A forming device includes a feeding component, an injection module, and a die-casting module. The feeding component has an internal space suitable for allowing a molten metal fluid to flow. The injection module is disposed on the feeding component and communicated with the internal space. The die-casting module has a mold cavity and a flow channel. The flow channel is aligned with the mold cavity and communicated with the internal space of the feeding component. The molten metal fluid flows to the die-casting module along the internal space, the injection module outputs a supercritical fluid into the internal space to mix with the molten metal fluid, and the feeding component pushes the molten metal fluid to pass through the flow channel and enter the mold cavity.

A mold device includes a frame that is a vertical wall having a first surface that is a vertical surface to which a holding mechanism is mounted and supported only by the first surface. A fixed mold base supporting a fixed mold, one surface thereof fixed to the first surface of the frame, and a mobile mold base supporting a mobile mold, the mobile mold base held by the holding mechanism so that the mobile mold base moves closer to and away from the fixed mold base. The holding mechanism includes a rail fixed to the first surface, and a guide fit on the rail in such a way that the guide moves on the rail while the guide is fixed to the mobile mold base. The mobile mold base is supported by the holding means without using a tie bar, and cantilevered on the first surface via the holding mechanism.

A die casting system can employ a counter piston to make central injection of large parts or multiple cavity parts possible. The die casting system can include a shot piston disposed on an injection side and a counter piston disposed on an ejector side. The counter piston can move between a sealing position to seal a liquid in the shot sleeve during pouring and slow injection phases, and an opening position to allow the liquid into the casting cavity during cavity injection phase.
