...Abstract Abstract Forging machines use a wide variety of hammers, presses, and dies to produce products with the desired shape, size, and geometry. This article discusses the major types of hammers (gravity-drop, power-drop, high speed, and open-die forging), and presses (mechanical, hydraulic...

... Radial forging machines, also referred to as rotary forging machines, are a modification of the traditional open-die press design that uses two sets of opposing dies, all of which apply deformation to the workpiece. Each pair of dies is arranged perpendicularly to the other as shown in Fig. 2 , which...

Meanwhile, the rim forms by backward extrusion without radial expansion and is also safe from fracture. The preform in Fig. 8...
