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.

The method can include: using a mold, casting an encapsulation onto a workpiece including solidifying the encapsulation around the workpiece in the mold and extracting the encapsulation from the mold, and cooling the extracted encapsulation using a vortex tube.

The invention relates to a device for removing at least one cooling element from an at least partially demoulded cast part, in particular from a cast housing for an electric motor formed from a light metal alloy, which has an apparatus for removing the at least one cooling element. Furthermore, the invention relates to a method for removing at least one cooling element from an at least partially demoulded cast part, a method for introducing at least one cooling element into a mould core of a cast part mould, a cooling element, and a cast part.

A system and method of increasing a cooling rate of a metal sand casting during solidification. The system includes a 3-D printed manufactured sand mold defining a mold cavity, a coolant inlet port extending into the manufactured sand mold, a myriad of coolant passageways surrounding a portion of the mold cavity, and a coolant outlet port in fluid communication with the coolant passageways. The system further includes a coolant vapor extraction system having a collection manifold in fluid connection with the outlet port of the sand mold. A molten metal is poured into the mold cavity and a liquid coolant is introduced into the sand mold. The liquid coolant changes state into a gas phase as it permeates through the sand mold, thereby increasing the cooling rate of the casting. The liquid coolant may be that of a liquid nitrogen.

A thermal system for casting process includes a set of centralized infrastructure components. The centralized infrastructure components include a central fluid reservoir providing fluid to the entire system. A control system for the thermal system is configured to supply fluids to a plurality of fluid lines corresponding to a plurality of casting circuits at various temperatures. The control system generates fluids for a plurality of casting circuits at various temperatures by mixing a plurality of fluid sources at different ratios.

A process for high integrity castings of metals and their alloys includes the steps of providing at least a sand mold at desired elevated temperatures, delivering a molten metal into the mold, and supplying a predetermined amount of coolant to contact the surfaces of the casting at desired rates, times, and durations to achieve an acceptable level of progressive solidification from the distal end of the casting towards the riser until the casting has reached desired temperatures.

An insert including a taper is covered with a molten metal. A metal molded product with the insert joined thereto is generated by semi-cooling the molten metal to a press-fitting temperature which is higher than a recrystallization temperature of the molten metal and lower than a melting point of the molten metal. A fitting hole which is filled with the insert is formed in the metal molded product. The taper is fitted into the fitting hole. An undercut is not formed in front of a tip of the taper. The insert is press-fitted into the fitting hole while pressing and extending the fitting hole with the taper in a thinning direction of the taper at a press-fitting temperature. The metal molded product is further cooled with the press-fitting maintained.
