Cross-wedge rolling (CWR) is a forging technique in which a heated billet is formed by rolling it between two flat (or cylindrical parallel-axis) die plates. This article describes the CWR process and equipment as applied to the production of railroad screws and other similar products.
A recent company survey indicates that forgers are more concerned with the availability of qualified labor than its cost. Given that, the forging community should consider automation to minimize its labor requirements. Automated billet feeding is one area that can improve manufacturing efficiency and reduce labor costs.
Western Superconducting Technologies Co. Ltd. (WST) successfully put a 63-/80-MN two-column open-die forging press into service. Supplied by SMS group, the high-speed push-down press has a maximum press force of 63 MN and an upsetting force of 80 MN. Due to the advanced hydraulic and control systems installed, the press is capable of forging highly demanding and temperature-sensitive materials such as titanium and titanium alloys with extreme precision.
For the third consecutive time, Cleveland played host to the biennial Forge Fair, which was held on the shores of Lake Erie May 21-23, 2019. Nearly 2,000 attendees and 169 exhibitors made Forge Fair 2019 the largest ever.
This fourth article about Germany’s Lightweight Forging Initiative (now with international industry support) focuses on potential weight savings through innovative material selection and forging part and process design. This continuation of the article from June examines additional specific lightweighting opportunities on a hybrid car and a heavy-duty truck.

Forging technology has undergone continuous development during the past few years.
Primetals Technologies and Mitsubishi Heavy Industries (MHI) will acquire ABP Induction Systems (ABP), a global manufacturer and servicer of induction furnaces and heating systems. ABP provides state-of-the-art equipment for ferrous and nonferrous metal casting, forging and steelmaking. Its main products are induction melting, holding and pouring furnaces as well as induction heaters. MHI and Primetals Technologies will jointly take ABP’s shares, and future business activities will be conducted in close cooperation with and under the leadership of Primetals Technologies.
India’s Bharat Forge Ltd. (Kalyani Group), a manufacturer of heavy-duty diesel crankshafts for commercial vehicles, rolled out its one millionth finish-machined crankshaft in mid-May. Bharat Forge, a long-standing supplier to Daimler AG, produces crankshafts that power Daimler’s heavy-duty engines. The company supplies machined crankshafts for the 13L and 15L engine platforms to Detroit Diesel in the U.S. Additionally, Bharat Forge shares the 13L platform with Daimler’s Mannheim plant in Germany.
Allegheny Technologies Inc. (ATI) agreed to sell two non-core forging facilities to Chicago-based Wynnchurch Capital LLC for $37 million. The transaction will close during the second quarter of 2019. The facilities, located in Portland, Ind., and Lebanon, Ky., are part of ATI’s High Performance Materials & Components (HPMC) segment. They use primarily traditional forging methods to produce carbon-steel forged products for use in the oil and gas, transportation, construction and mining industries. Their capabilities include comprehensive forging processes complemented by in-house design and engineering, product machining and heat-treating services.
Material-handling automation plays a key role in today’s forging equipment solutions. Even older equipment can be updated and upgraded to take advantage of automation technologies that improve safety and increase production efficiency in your plant.
