Greenleaf Corporation of Saegertown, Pa., is a supplier of industrial cutting tools. The company specializes in the manufacture of high-performance carbide and ceramic inserts, tool-holding systems and custom-designed tooling solutions.
Wynnchurch Capital acquired Pennsylvania Machine Works (Penn Machine), a fully integrated manufacturer of high-pressure forged fittings and branch connections. Headquartered in Aston, Pa., Penn Machine produces high-quality products in a diverse variety of material grades that are sold into the downstream oil and gas, petrochemical, industrial and shipbuilding end markets. The company is supported by its forging facility in Swedesboro, N.J., and two machine shops in Aston and Houston, Texas.
The Ellwood Closed Die Group (ECDG) completed construction of its climate-controlled close-tolerance finish machining complex at its Ellwood Texas Forge Navasota (ETFN) facility. The new operation concludes a year-long initiative to integrate operations of the former Ellwood Texas Forge and Machine with ETFN to improve customer solutions and to better leverage engineering and management resources. Capabilities include turning, milling, drilling, boring and single-point threading operations, with up to 14,000 square feet serviced by several overhead bridge cranes.
Direct metal deposition (DMD) is a powder jet additive-manufacturing (AM) technique that can be used for low-cost build, repair, hardfacing and reconfiguration of forging dies. The technique has also been used to add features such as flanges and bosses to forged parts to improve their functionality. This article uses four case studies to examine this technique in detail and compares its merits and limitations to conventional and other AM/welding techniques.
Sheffield Forgemasters installed the U.K.’s largest five-axis vertical turning lathe (VTL) as part of a $7.9 million upgrade to its machining facilities. The project will improve capacity and throughput for complicated machining requirements. Weighing almost 250 metric tons, the VTL was manufactured by Spanish company BOST. It has a maximum machining height of 13 feet (4 meters), maximum swing diameter of 28 feet (8.5 meters) and a table weight capacity of 100 metric tons.
Forging companies are often faced with the decision about whether to add services to offer their customers. The investment in and addition of, for example, heat treating or machining service departments to your operation are viable growth strategies.
HBD Industries of Dublin, Ohio, parent company of California Drop Forge and Precision Metal Products, announced the expansion of its Precision Components Group through the acquisition of True Position Technologies LLC of Valencia, Calif. True Position provides complex machined components for flight control applications and specializes in the manufacture of high-specification components that require multiple machining, testing and finishing processes within extremely tight tolerances.
