Forge shops can increase productivity and reduce costs in hot-forging and heat-treatment processes using synthetic lubricants and/or protective coatings. Hard coatings cold-welded onto high-wear areas of dies or anti-oxidation coatings painted directly onto forging billets can help.
Protective coatings continue to play a major role in increasing productivity and reducing costs in hot forging and heat treatment. This paper presents details and successful case studies of three such protective coatings.
Sheffield Forgemasters will lead a consortium of partners in a research-and-development project to explore the industrialization of electron-beam welding (EBW) in civil nuclear assemblies, with the potential to integrate welding into the manufacturing process. The Sheffield, U.K., company will install an electron-beam welder capable of welding 3-meter-diameter cylinders under localized vacuum and without traditional welding preparation, offering narrower welds than traditional methods plus the ability to weld as part of the manufacturing process, prior to quality heat treatment. It will then manufacture a civil nuclear component to demonstrate a full-sized (4.3 meters high x 3 meters diameter) small modular reactor pressure vessel and also produce several grades of steel alloys suitable for civil fission and fusion nuclear applications within the project's research element.

OSR Inc., a manufacturer of automotive fasteners, plans to increase its manufacturing production in Columbus, Ind. The company, a joint venture between Japan’s Owari Precise Products Co. and Columbus-based Rightway Fasteners Inc., will invest $7 million to construct and equip a new 82,395-square-foot manufacturing facility. OSR plans to add up to 12 new positions and is hiring immediately for positions in heat treatment and IT. Production is scheduled to increase at the beginning of 2020. OSR, which currently has 29 employees, specializes in M4 to M9 cold-forged fasteners, primarily for Toyota.
High-temperature insulating wool (HTIW) products boast significant advantages compared to traditional refractory products on investment cost, operating expenses, reliability, overall efficiency and the fast availability of the equipment following relining or maintenance and repair work.
The Ellwood Closed Die Group (ECDG) is launching a new product line for Seakeeper. The line includes finish-machined flywheels that are assembled into gyro stabilizers, which, according to Seakeeper, cut down “95% of all boat roll, the rocking motion that causes sea sickness, anxiety and fatigue.” Ellwood Texas Forge Navasota (ETFN) will use the entire Ellwood Group supply chain to manufacture the flywheels from start to finish.
