A component formed of metal, such as aluminum, and including a hollow core is provided. The component can be used as a cradle, rail, A-pillar, twist axle, control arm, or shock tower, for example. The component is manufactured by a high pressure vacuum die casting (HPVDC) process. To form the component with the hollow core, a blown or stamped hollow glass core is placed in a die cavity of the high pressure vacuum die casting apparatus, and the metal is melted and injected into the die cavity around the glass core. The metal is then cast and solidifies around the glass core. After the casting process, the glass core can be shattered, removed from the cast component, and recycled.

Various embodiments may include a method for removing filling material from a cavity in a manufactured component with a connection from the cavity opening to surroundings of the component, the method comprising: holding the component in a movable mounting; moving the component and at the same time removing the filling material through the connection opening; and executing a computer program with a processor, wherein the computer program instructs the processor to: analyze geometry data of the component including the connection opening; and calculate a necessary positioning of the component, based on the geometry data and gravitational force; and direct the movable mounting through a sequence of movements for moving the component in space to spill the filling material from the cavity through the connection opening out of the component.

A hammer includes a jacket having an inner chamber; an inlet circuit for the entry of compressed air, and an outlet circuit for the exit of compressed air. The hammer includes a motion mechanism, for generating vibratory motion under the action of compressed air; and a punch or beater, connected to the motion mechanism, for contacting the casting to be de-cored, forming a first end of the hammer. The hammer has a measurement circuit measuring the oscillation frequency of the motion circuit. The measurement circuit includes a sensor for measuring the oscillation frequency of the motion circuit; a processing circuit, enclosed in a protective casing, for receiving electric signals transmitted by the sensor, and a communication line for conducting electric signals from and/or to the measurement circuit. The jacket includes a housing formed in the outer surface of the jacket, such that it incorporating the measurement circuit protective casing.

A hammer includes a jacket, which includes an inner chamber, an inlet circuit for entry of compressed air, and an outlet circuit for exit of compressed air. The hammer further includes a motion mechanism, for generating a vibratory motion under the action of compressed air; and a punch or beater, connected to the motion mechanism, for coming into contact with the casting to be de-cored, forming a first end of the hammer. The inlet circuit includes an inlet connector for connecting the hammer to a compressed-air circuit; the inlet connector being located at a second end of the hammer, opposite to the end where the punch or beater is located. The outlet circuit has an outlet connector for connecting the hammer to an air recovery circuit. The outlet connector is located at the second end of the hammer, in proximity to the inlet connector.

A pneumatic hammer or de-coring vibrator is for de-coring of foundry castings. The hammer includes a jacket, in turn having an inner chamber; an inlet circuit for the entry of compressed air, and an outlet circuit for the exit of compressed air. The hammer further includes a motion mechanism for generating vibratory motion under the action of compressed air. The motion mechanism is arranged within the inner chamber of the jacket; and a punch or beater is connected to the motion mechanism, for coming into contact with the casting to be subjected to de-coring. The jacket of the hammer is made of an alloy including aluminum, silicon and magnesium.

A method of manufacturing a core for casting a component can include manufacturing a core for at least partially forming an internal passage architecture of a component with a material including radiopaque particles. A method can include removing a material including radio opaque particles from an internal passage architecture of a component; and inspecting the component via radiographic imaging at gamma/X-ray wavelengths to detect residual material. A core for use in casting an internal passage architecture of a component can include a material with radiopaque particles dispersed therein.

Provided is a manufacturing method of a faucet, including: (1) fabricating a liner with a cavity; (2) injecting a liner filler into the cavity of the liner, and allowing forming of the liner filler in the cavity; and (3) placing the liner injected with the liner filler in a mold, conducting high-pressure die casting, cooling for solidification, and removing the liner filler from the cavity to produce the faucet. The liner filler is one or more of a resin, a silica gel, a foam material, a resin sand, a steel ball, a cement, a wood shaving, a flour, a wax, an ice, and a dry ice. A raw material for fabricating the liner is at least one of a stainless steel, a titanium metal, copper, and aluminum. The method is simple and features low difficulty in industrial production. The faucets have a smooth liner, regular appearance, and excellent consistency.
