A casting device and a diecasting method, preferably a vacuum die-casting method, includes a casting chamber having a filling opening, and a casting piston that can be moved in the casting chamber and is connected with a casting drive by way of a casting piston rod. The device also includes a feed line, by way of which casting material can be filled into the casting chamber through the filling opening. The casting chamber is disposed, at least in part, in a sleeve that is mounted so as to rotate.

A method of casting is provided, wherein a molten material is introduced into a mould such that the molten material flows out of the mould, wherein once a desired temperature of the mould is achieved, the molten material is prevented from flowing out of the mould such that the molten material at least partially fills the mould.

Apparatus and methods for injecting molten filler material into a hole. The method in accordance with one embodiment comprises: drilling a hole in a composite layer; heating filler material comprising an electrically conductive low-melting alloy to a molten state; inserting a nozzle having an internal channel system into the hole with a gap separating the nozzle and the hole; forcing molten filler material into, through and out of the internal channel system of the nozzle and into the gap; and retracting the nozzle from the hole. The nozzle may be rotary or not rotary.

According to a first embodiment, a molten metal transferring system is provided. The system includes a device capable of lifting molten metal from a bath to a launder at varying quantity per unit of time. The system includes a sensor, such as a laser, arranged to monitor molten metal flow in the launder. The launder further includes a removeable insert facilitating, reversible modification of a cross-sectional area of the launder.

An apparatus for low-pressure casting includes a furnace wall bounding a furnace chamber, a melting crucible unit located in the furnace chamber, a heating device for heating the melting crucible, and at least one pressurizing unit for applying overpressure to the melting crucible. The furnace chamber in a top view has a length which is greater than its width, so that the furnace chamber has an elongated shape in a longitudinal direction, wherein preferably several riser pipes extending vertically are distributed roughly evenly over around 60% to 95% of the length in the longitudinal direction of the melting crucible or crucibles.

A casting device is provided with: a positioning member that is provided to a base and comes into contact with an upper mold and a slide member to define the positions of the upper mold and the slide member at the time of mold clamping; and a restraining force-applying mechanism for applying a restraining force to the slide member in a direction opposite a pressing force acting on the positioning member from the slide member at the time of mold clamping of the slide member.

A self-cleaning transfer gear pump for transferring molten metal includes the following features: a transfer conduit extends upward from an outlet of a base, two rotatable gears are formed of refractory material and disposed in the gear chamber and engage each other during rotation. A boss functioning as a bearing extends from the drive gear and is adapted to be received in an opening in the base. A shaft is fastened at a lower end to the drive gear. A filter is fastened to the base so as to cover the inlet and prevents particles and objects in the molten metal from entering the gear chamber. In operational mode, a motor rotates the shaft and the drive gear whereby the drive gear and the second gear engage each other while being rotated so as to positively displace molten metal from the inlet to the outlet and along the transfer conduit to the remote location. In self-cleaning mode, the motor rotates the shaft and the drive gear effectively to draw molten metal from the transfer conduit by positive displacement, through the outlet, and toward the inlet therefore cleaning the filter by removing the particles adhering to the filter. Also included are a system with optional filter and optional self-cleaning mode but including an inlet portion of a die casting machine, and a method for operating the gear pump. A flow sensor may be used to transmit pulses into and from the transfer conduit so as to enable determination of a volume of molten metal being charged. The control of the molten metal volume being charged is not solely controlled by the flow sensor.
