Embodiments of heat spreaders with integrated preforms, and related devices and methods, are disclosed herein. In some embodiments, a heat spreader may include: a frame formed of a metal material, wherein the metal material is a zinc alloy or an aluminum alloy; a preform secured in the frame, wherein the preform has a thermal conductivity higher than a thermal conductivity of the metal material; and a recess having at least one sidewall formed by the frame. The metal material may have an equiaxed grain structure. In some embodiments, the equiaxed grain structure may be formed by squeeze-casting or rheocasting the metal material.

A method for producing a strip using a rapid solidification technology is provided. A melt is poured onto a moving outer surface of a rotating casting wheel, the melt is solidified on the outer surface and a strip is formed. A gaseous jet is directed at the moving outer surface and the outer surface of the casting wheel is worked with the jet. The jet comprises CO.sub.2 and at least part of this CO.sub.2 strikes the moving outer surface of the casting wheel in a solid state.

A hybrid casting process for structural components uses a re-usable metallic mold rather than a sand mold to produce more consistent cast components. The hybrid casting process uses a metallic mold coupled to a core mold to produce the near net shape of the cast component. Machining operations are performed on the near net shape cast component to produce a final component that meets tolerances and other specifications of the structural component.

A precast hole scab removing device is provided. The precast hole scab removing device is composed of a stand, floating columns, ejector pins, an air cylinder, clamp cylinders, supporting poles and the like. In use, a hole I and a hole II in a workpiece respectively match with a tapered part of a left floating column and a tapered part of a right floating column; by pressing down the workpiece, locating parts of the workpiece simultaneously match with the top end of a supporting pole I, the top end of a supporting pole II and the top end of a supporting pole III, a clamp cylinder I, a clamp cylinder II and a clamp cylinder III press the workpiece tightly, and at the moment, the workpiece is completely located; the air cylinder lifts down a lifting plate and the ejector pins through two guide pillars, the ejector pins are pressed into holes, in which scabs need to be removed, of the workpiece; and therefore, the scabs can be ejected out of the workpiece. The precast hole scab removing device can remove the scabs of precast holes of casting workpieces in use, the removing efficiency is high, the scabs are removed cleanly, and additionally, the precast hole scab removing device has the characteristics of high automation degree, simple structure, low manufacturing costs and the like.

A smart trim die assembly for providing multiple internal operations during a stroke. The smart trim die assembly (10) comprises a first die (12), a second die (14), and a cavity (20) formed between the first die and second die. A plurality of sensors (22) are located between the first die and the second die for measuring the distance therebetween during a stroke. A series of tools are integrated into one of the first die or second die and each perform one of trimming, piercing, dimpling, and tapping operations. The smart trim die assembly further includes a processor (210) and a memory device (214) for receiving readings from the sensors. The memory device further contains instructions that, when executed by the processor, cause the processor to, in response to the sensor reading a predetermined distance, instruct the series of tools to perform one or more of the operations.

A method of forming a component for a gas turbine engine, including: casting a component around a ceramic core, wherein the ceramic core forms a pilot channel (40) in the component, the pilot channel oriented from a base (176) to a tip (20) of the component; sinking an ECM electrode into the pilot channel; and enlarging the pilot channel to form an inner surface of an external wall (120) of the component via electro-chemical machining, wherein a contour (94) of the inner surface is different than a contour of the pilot channel.

Aspects of the disclosure generally relate to a casting mold for forming a cast part. The casting mold includes a casting shell having an internal surface bounding an interior, and a casting core positioned within the interior to define a cavity between the casting core and the casting shell, whereby the internal surface of the casting shell defines an outer surface of the cast part.

Provided is a double-station cleaning system comprising a cleaning machine, wherein workpieces are placed into the feeding frames, the feeding frames are placed into trays, the bracket assembly is pushed to drive the trays to move along the guide rail assembly, the feeding frame in one of the trays is conveyed to a feeding inlet of the cleaning machine, the feeding frame is pushed to move along two rows of nylon wheels and linear guide rails inside the cleaning machine, and the feeding frame and the workpieces in the feeding frame are pushed into the cleaning machine so as to be cleaned. The double stations work alternately, so that the work time is saved, and the work efficiency is increased.
