Below is a list of Alloy Castings manufacturers from Machesney Park, Illinois. Alloy castings are die cast products that are formed out of metal alloys. During this process, the alloys, which are usually non-ferrous (not containing iron) are heated until molten and injected into a mold, where they solidify and take a certain shape to form a vast array of different parts and products for the automotive, aerospace, construction, commercial product manufacturing and many other industries. They may be as complex as a vehicle's transmission housing or as simple as a door handle.
