A method of over-molding a hybrid sub-assembly onto a base structure includes providing a mold for an over-molding process. The mold may comprise a lower mold tool, an upper mold tool, and a tube locator positioned on one of the upper mold tool or lower mold tool. A base structure formed of a first material is located into the tube locator. A mandrel tool is inserted into an opening in the base structure. The upper and lower mold tools are closed and clamped shut. A second material, such as a lighter weight or lower density material is heated to at least a semi-solid or slurry state. The semi-solid or slurry is injected into the mold to form a molded sub-assembly that is mechanically bonded to the base structure.

A vacuum die casting method may include: coupling a fixed die and a movable die to each other; closing a molten metal pouring hole formed in a sleeve using an injection plunger operated in the sleeve, which is formed on a lower side of the fixed die or the movable die; performing vacuum decompression in a cavity formed between the fixed die and the movable die using a vacuum decompression device connected to chill vent blocks provided on upper portions of the fixed die and the movable die; supplying oxygen in the cavity using an oxygen supply device connected to the chill vent blocks after completing the step of performing vacuum decompression; and supplying a molten metal to the cavity through the molten metal pouring hole.

The neck is configured for combination with a club; the hitting panel is connected to the bottom of the neck; the peripheral wall is located on a rear surface of the hitting panel, the peripheral wall forms a rear concave cavity with the hitting panel; the cushion block is embedded in the peripheral wall to reduce the casting thickness of the peripheral wall, and provided with a plurality of pillars thereon, wherein one end of each pillar is fixedly connected to the cushion block body, and the other end of the pillar has an exposed surface or exposed section not covered by the peripheral wall; and the adjusting member is matingly connected to the pillar.

A die casting machine with a die casting mold produces metal die cast parts. The die casting machine has a first machine shield, to which a first mold half of the die casting mold is secured, and a second machine shield, to which a second mold half of the die casting mold is secured. In order to compensate for the deflection of the machine shields, an intermediate plate which has at least two temperature-controlling devices that can be used to generate a temperature difference leading to the curving of the intermediate plate is arranged between the first machine shield and the first mold half and/or between the second machine shield and the second mold half.

A casting apparatus for manufacturing a cast product from molten metal includes a molten metal and a cooling portion. The molten metal contacts a surface for contact with the molten metal. The cooling portion forms a cooling flow passage. The cooling flow passage is configured to cool the molten metal contacting surface. At least a part of an inner surface of the cooling flow passage is constituted of a welding portion formed by welding, the welding portion sealing the cooling flow passage. The welding portion is constituted such that an exposure to the molten metal becomes equal to or less than a predetermined ratio with respect to an area of the welding portion constituting the inner surface of the cooling flow passage.

Disclosed is a high-temperature alloy pressure casting mold for an impeller and a guide vane. The high-temperature alloy pressure casting mold includes a casting main pipe, a lower casting pipe, and forming steel mold assemblies, wherein the plurality of forming steel mold assemblies surround the casting main pipe, the casting main pipe is provided with a pressure device, the bottom of the casting main pipe is connected to a casting gate at the bottom of each forming steel mold assembly by means of the lower casting pipe, and casting is carried out using pressure supplied by the main pipe. Further disclosed is a high-temperature alloy pressure casting process for an impeller and a guide vane using the casting mold.

A casting device in which refrigerant is pressure-fed to a cooling passage formed in a die, leakage of refrigerant in the die can be reliably detected in a short time without a significant modification applied to the conventional device. A casting device includes a pressure-feed device that pressure-feeds refrigerant to a cooling passage formed in a die, and a release agent coating applicator that applies a release agent to the die, and further includes a unit that mixes a fluorescent agent into the refrigerant (fluorescent agent tank), a unit that irradiates the die surface of the die with black light while the refrigerant containing the fluorescent agent mixed therein is pressure-fed to the die, and an imaging device that captures an image of the die surface. The imaging device is integrally assembled with the release agent coating applicator.

A semi-solid metal in-cavity molding die includes a die body. The die body includes a male die and a female die, a cavity formed by the male die and the female die, a runner communicated with the cavity and a sprue communicated with the runner are provided inside the die body. An inner wall of the runner is provided with a plurality of guide protrusions which are arranged in a spiral track. The guide protrusions combine the inner wall of the runner to form a special-shaped pipeline for molten metal to flow through, and a cooling mechanism arranged around the runner is further provided in the die body.

Method for near-contour surface temperature control of shell-shaped molds (14) with mold rim zones (1), wherein the temperature control of the mold (14) on a near-contour temperature control surface (4) with adjacent, web-like or wall-like separated subareas (4.i) is effected from the respective rear space (3) of the mold rim zones (1) of the mold (14) and/or the respective mold rim zone (1) of the mold (14). The shell-shaped molds (14) are designed in two or more parts with the respective mold rim zones (1). Specifically, the temperature control as cooling in the form of temperature control on the temperature control surface (4) is locally different in subareas (4.i). The temperature control surface (4) is effected in accordance with the temperature ranges of convection, bubble evaporation, partial and/or stable film evaporation of the liquid cooling fluid water.
