A method for accelerating the creep age forming of a metallic component is provided. The method includes the steps of applying static loading and ultrasound vibrations to the local regions on a metallic component during the creep age forming process. The transmission of ultrasound in the component enhances the mobility of dislocations and atoms and thus accelerates the creep deformation in the component.

A three-plate die casting mold for producing a metal die-cast part by die casting a molten metal includes a first, second, and third mold part, where the third mold part is disposed between the first and second mold parts. Molten metal is feedable to a die cavity through a sprue system where the sprue system has a plurality of feed channels that are disposed in the third mold part and open into the die cavity. The plurality of feed channels have a respective tapering at a die cavity-side end where the respective tapering locally decreases a channel cross section such that a predetermined breaking point is generated during a die casting operation which allows a defined separation of the metal die-cast part from a sprue created in the sprue system when the three-plate die casting mold is being opened.

An injection device and method for producing at least one metallic glass part, in which a vertical piston is able to move in a vertical direction, a top end portion of the piston being suitable for being engaged in an injection chamber of a mould linked to a cavity of this mould and open at the bottom; the piston having a top end face on which an element made from metallic glass to be introduced into said chamber can be positioned, the top face of the piston having a concave shape suitable for receiving a bottom portion of the element made from metallic glass. A heating means situated under the mould comprises induction coils, such that, when the piston is in an intermediate position, the majority of the metallic element is situated in the space surrounded by the induction coils.

With excellent heat retention of molten metal and better productivity/work environment, regardless of low-speed or high-speed, the usable die lubricant for die casting will be provided. An aqueous die lubricant for die casting in which a phyllosilicate mineral is dispersed at a concentration of 0.005 wt % or more and less than 5 wt % and has a particle diameter of 0.1 μm or less during the dispersion.

A pressure intensifier device increases pressure in a pressurized fluid chamber of a piston/cylinder unit. The pressure intensifier device has a pressure intensifier cylinder and a pressure intensifier piston, which is guided in an axially movable manner in the cylinder, wherein the pressure intensifier cylinder has an outlet region, an inlet region upstream of the outlet region and a piston guiding chamber, and the pressure intensifier piston has a piston part, which is guided in the piston guiding chamber, and a piston rod, which extends from the piston part to the inlet region, in a maximally retracted release position releases a fluid connection between the inlet region and the outlet region and, in a maximally advanced blocking position, blocks this connection with a free end portion, with which it extends into the outlet region. Over a portion that can be passed through by the free end portion of the piston rod during movement from the release position into the blocking position, the outlet region has a free passage cross section for the free piston rod end portion that is at least equal in size to a rod cross section of the free piston rod end portion. A pressure intensifier inlet valve can be controlled independently of a pressure in the pressurized fluid chamber of the piston/cylinder unit.

A process of forming an erosion, oxidation, and wear resistant shot chamber, either a gooseneck or a shot sleeve, is provided. The process utilizes a shrink fitting process for forming a one-piece shot chamber having a liner bonded to the bulk portion of the shot chamber. Channels of predetermined shape and layout are built on the tubular external surface of the liner for facilitating thermal management of the shot chamber during die casting operations.

A differential carrier case with an inserted pipe for high pressure casting may include a mold core into which a first end of a pipe is inserted, a mold core pin fixed to the mold core to fix the mold core and the first end of the pipe, a drive core pin inserted into a second end of the pipe, and a thick portion surrounding an outer portion of the pipe.

An injection chamber or container for machines for pressure die-casting processes is provided, which is formed by a cylinder (1) includes an external cuff (2) and an internal insert (3), through which passes material that is introduced through an opening (4) and pressure-driven by means of a piston (5) into a mould (6). The internal insert (3) has an outer diameter (d) smaller than the inner diameter (D) of the external cuff (2), there being between the two diameters (d, D), a difference of dimension (a) such that the insert (3) can be inserted into and removed from the cuff (2) directly and cold, that is, without dilating it, and such that the only dilation that the insert undergoes (3), which is caused by the heat of the material to be extruded that passes therethrough when the cylinder (1) is operating, causes the insert to become fixed inside the cuff (2).

The disclosure provides a local extrusion device for high-pressing casting. The local extrusion device for high-pressure casting includes an extrusion core sleeve, an extrusion rod, an extrusion oil cylinder and an extrusion oil cylinder piston. The extrusion oil cylinder includes the extrusion oil cylinder piston, the extrusion oil cylinder piston is connected with the extrusion rod, the extrusion rod is positioned in the extrusion core sleeve, and the extrusion core sleeve and the extrusion oil cylinder are fixed.
