Molten metal before casting Casting iron in a sand mold. In metalworking and jewelry making, casting is a process in which a liquid metal is delivered into a mold (usually by a crucible) that contains a negative impression (i.e., a three-dimensional negative image) of the intended shape.
In 2007, the company purchased Cherry Aerospace to expand their fastener business. [9] After ranking as the 568th largest U.S. company by Fortune in 2007, [10] the company became a Fortune 500 the next year when it ranked 444, and rose to 362 in 2009. [3] It ranked 322 prior to its sale to Berkshire in 2016.
The cast metal from the twin-belt continuous casting machine is synchronized with, and directly fed into, a hot rolling mill. Combining the casting and rolling operations can result in significant energy and cost savings over other casting processes which incorporate intermediate cast and reheat steps.
The mill was incorporated as the Henry River Manufacturing Company. The company manufactured fine cotton yarns. Beginning in 1905, a 30-foot (9.1 m) reinforced concrete dam was constructed with a three-story brick mill building. In its early years, the mill operated 4,000 yarn-making spindles.

Metal stitching is an industrial technique for repairing cracked and broken cast iron, steel, bronze or aluminium structures and their components. The process is carried out cold, without welding . It allows the repair of cast iron and cast steel , often in-situ, without the distortion from welding , and can be used in other situations where ...
David Kirkaldy (1820–1897) was a Scottish engineer who pioneered the testing of materials as a service to engineers during the Victorian period. He established a test house in Southwark, London and built a large hydraulic tensile test machine, or tensometer for examining the mechanical properties of components, such as their tensile strength and tensile modulus or stiffness.
Cast iron development lagged in Europe because wrought iron was the desired product and the intermediate step of producing cast iron involved an expensive blast furnace and further refining of pig iron to cast iron, which then required a labor and capital intensive conversion to wrought iron.
