The diecasting mold further comprises a demolding system, the demolding system comprising an ejector assembly, a drive device, and a force transmission device. A hot chamber system for diecasting metal melt according to the hot chamber method is also taught, a method for diecasting metal, and a use of a diecasting mold.

A casting plunger system for a die casting machine includes a stationary system part and a system part which moves relative to the stationary system part in a respective casting cycle for the introduction of melt material into a casting mould. The moved system part has a plunger, a plunger rod and a rod drive unit, and is configured to decelerate at the end of a mould filling phase of the casting cycle under the effect of pressure on the melt material. A casting method for a die casting machine is provided with such a plunger system. The moved system part has a mass which can be adjusted variably between different casting cycles, and/or the moved system part consists of a moved main system part and an additional mass unit which is arranged so as to be movable relative to the main system part and is configured to decelerate, at the end of the mould fill phase of the casting cycle, later by a predefined delay time than the main system part.

A system (5) and method (800) for unit cell casting of titanium or titanium-alloys is disclosed herein. The system (5) comprises an external chamber (45), a crucible (10) positioned within the external chamber (45), an induction coil (15) positioned around the crucible, an internal chamber (40) positioned within the external chamber (45), and a mold (30) positioned within the internal chamber (40). The external chamber (45) is evacuated and a pressurized gas is injected into the evacuated external chamber (45) to create a pressurized external chamber (45). An ingot (20) is melted within the crucible utilizing induction heating generated by the induction coil (15). The internal chamber (40) is evacuated to create an evacuated internal chamber (40). The titanium alloy material of the ingot (20) is completely transferred into the mold (30) from the crucible (10) using a pressure differential created between the external chamber (45) and the internal chamber (40).

A process for the casting of metals and their alloys includes the steps of providing at least a mold equipped with a plurality of cooling nozzles, making a layer of coolant permeable materials covering the nozzles and maintaining the materials at desired temperatures, delivering a molten metal into the mold, supplying predetermined amount of coolant to each nozzles to contact the casting at desired rate, time, and duration to achieve an acceptable level of progressive solidification from the distal end of the casting towards the riser until the casting has reached desired temperatures.

A method and apparatus for producing semi-solid material castings from its liquid state in a shot chamber of a die casting machine where the liquid material is poured into a shot chamber and rapidly cooled from its liquid state to temperatures below its liquidus. High-intensity ultrasonic vibration is coupled to the plunger, shot plate, or sprue-spreader while the cast material is injected by the plunger to fill the die cavity. The combined action of rapid cooling from the shot chamber, vigorous pushing by the plunger, and radiation of ultrasonic vibration on the cast material in the shot chamber directly turns the initial liquid material directly into a semi-solid slurry by breaking up dendrites and making these dendritic fragments globular. The slurry is then injected into the die cavity to form a casting.

A molding machine for molding material is provided. The machine includes a cavity to be filled with molten metal and a conduit system leading to the cavity, thus forming a system of interconnected hollow spaces. At least one pressure member is moveable in at least part of the conduit system. A centrifugal pump in fluid communication with a reservoir of molten metal is provided, the pump providing molten metal to the hollow space receiving the at least one pressure member.

An injection system applied to a die casting machine includes a container module, a first mold module, a second mold module, and a pipe module.
