A method to manufacture reticulated metal foam via a dual investment solid mold, includes pre-investment of a precursor with a diluted pre-investment ceramic plaster then investing the encapsulated precursor with a ceramic plaster.

A method to manufacture reticulated metal foam includes coating a precursor in a molten wax to increase ligament thickness; and investment coating the molten wax coated precursor with a ceramic plaster.

A system and methods are provided for removing core elements of cast components. In one embodiment, a method includes controlling a first high temperature autoclave cycle for a cast component in a vessel with a first solution concentration to remove at least a first portion of core elements, wherein the first solution concentration, temperature and pressure in the vessel are controlled to expose one or more casting pins in the cast component. The method may also include controlling a second high temperature autoclave cycle for the cast component in the vessel with second solution concentration, wherein the second solution concentration, temperature and pressure in the vessel during the second high temperature autoclave cycle are controlled to loosen one or more of the casting pins from the cast component, and controlling one or more low temperature autoclave cycles to remove core and casting pins from the cast component.

A method to manufacture reticulated metal foam via a dual investment, includes pre-investment of a precursor with a diluted pre-investment ceramic plaster then applying an outer mold to the encapsulated precursor as a shell-mold.

In accordance with one aspect of the present embodiment, disclosed is a system and method of processing sand mold castings including the steps of placing a mold on a translation surface of a first conveyor at a first position, the mold including a sand housing having compacted sand that encapsulates a casting. The mold is translated along the translation surface of the first conveyor from the first position towards a second position. Air is directed against the casting and temperature of the air and or casting is measured after the casting is being removed from the sand mold.

Provided are a brake disc and a brake disc manufacturing method. The brake disc manufacturing method may include a porous metal block preparation operation for preparing a porous metal block having a plurality of pores therein, and an insert casting operation for mounting the porous metal block in a mold and casting a disc plate material to manufacture a brake disc.

A core discharge device is provided for discharging a sand core from a cast material in which the sand core contains a binder having water glass. The core discharge device includes a humidified gas supply device that supplies humidified gas to the sand core inside the cast molded article. The humidified gas is a gas to which humidity has been added and from which droplets have been removed.
