Disclosed are embodiments of a temperature regulated vessel and a fluid delivery device, and methods of use thereof. The vessel can be used in an injection molding apparatus and include one or more temperature regulating lines configured to flow a fluid or liquid within the body (e.g., to heat a cold device). The fluid delivery device is mounted in the apparatus and has a collar with an opening extending therethrough to sealingly mate with the vessel. A delivery channel is provided within the collar for directing an input flow of fluid into the vessel. An exit channel can also be provided within the collar for directing an output flow of the fluid from the vessel.

The present disclosure is directed to a method of physically separating and electrically isolating the chamber where the ohmic heating of the feedstock occurs by delivering current through the electrodes (heating barrel), from the chamber where the feedstock deformation and flow through the runner takes place by the motion of the plungers (forming barrel). The method also includes transferring the feedstock from the heating barrel to the forming barrel between the heating and the forming processes at a high enough rate such that negligible cooling and no substantial crystallization of the feedstock occurs during the transfer.

A piston of a die-casting apparatus comprises: a piston head fabricated of a first material; an elongate, inner carrier coupled to the piston head; a generally annular body seated on the carrier adjacent the piston head; and a wear ring disposed on the piston head, the wear ring being fabricated of a second material. The first material has a higher toughness and a lower hardness than the second material.

A sprue system for a diecasting die includes at least one runner channel, which extends from an entry-side sprue mouth opening to an exit-side sprue opening, which opens into a die cavity of the diecasting die that is formed between a fixed die half and a movable die half or into a gate region arranged upstream thereof. The runner channel has a geometrically and/or thermally defined parting region upstream of the sprue opening and downstream of the sprue mouth opening. The runner channel has a bend or kink in the parting region and/or a heating device is assigned to a runner channel portion between the parting region and the exit-side sprue opening and/or a heating device is assigned to a runner channel portion adjoining the parting region upstream and narrowing conically toward the parting region and/or a region of the movable die half opposite the sprue opening has a cooling channel structure.

Provided is a high-pressure casting method and a high-pressure casting device which are capable of safe and high-quality casting of a high-fusion-point metal having a fusion point exceeding 1000 K. After melting a casting material (1) inside a melting container (2) of cartridge type, the melting container (2) is linearly moved to pass through a guide (14) attached to a casting port bush (13) to thereby be communicated with the casting port bush (13). The melting container (2) is brought into close contact with the guide (14) and is setting to a cooling state. After the elapse of prescribed time, a plunger (50) is brought into contact with a plunger tip (4), and is immediately transferred together with a molten metal to the casting port bush (13). The molten metal is pressurized inside the casting port bush (13), and is injection-filled into a cavity (10).

There is provided an injection molding machine including a backflow prevention device configured to perform a backflow prevention operation in which the communication path is closed to prevent a backflow of the molten material. The backflow prevention device includes a sealing seat that is provided in the communication path, a valve rod that is movable to come in contact with the sealing seat, and a fitting portion in which the sealing seat as an end is fitted to the valve rod. The backflow prevention operation includes at least one pumping operation in which a front of the valve rod moves from a position at which the front is not fitted to the fitting portion to a position at which the front comes in contact with the sealing seat.

A shot sleeve for a die casting machine includes a shot sleeve body with a pour opening that extends to a spaced apart inner and outer diameters. The shot sleeve body is a first material. A liner is secured to the shot sleeve body beneath the pour opening. The liner is a second material. The shot sleeve body and the liner together provide a plunger surface defining a cavity that is configured to receive a molten shot of material.

A metal forming apparatus includes an injection device and a displacement speed monitoring device. The injection device includes a moveable injection rod defining a sliding channel, and a magnet ring disposed on the injection rod, the displacement speed monitoring device includes a housing sealedly connected to the injection device, and a linear displacement sensor disposed in the housing, a rear end of the injection rod is extended into the housing such that a front end of the linear displacement sensor is located in the sliding channel.

Disclosed are embodiments of a temperature regulated vessel and a fluid delivery device, and methods of use thereof. The vessel can be used in an injection molding apparatus and include one or more temperature regulating lines configured to flow a fluid or liquid within the body (e.g., to heat a cold device). The fluid delivery device is mounted in the apparatus and has a collar with an opening extending therethrough to sealingly mate with the vessel. A delivery channel is provided within the collar for directing an input flow of fluid into the vessel. An exit channel can also be provided within the collar for directing an output flow of the fluid from the vessel.

A rapid discharge heating and forming apparatus is provided. The apparatus includes a source of electrical energy and at least two electrodes configured to interconnect the source of electrical energy to a metallic glass sample. The apparatus also includes a shaping tool disposed in forming relation to the metallic glass sample. The source of electrical energy and the at least two electrodes are configured to deliver a quantum of electrical energy to the metallic glass sample to heat the metallic glass sample. The shaping tool is configured to apply a deformational force to shape the heated sample to an article. The at least two electrodes have a yield strength of at least 200 MPa, a Young's modulus that is at least 25% higher than the metallic glass sample, and an electrical resistivity that is lower than the metallic glass sample by a factor of at least 3.
