Forging - the oldest means of metalworking - includes methods of plastically deforming a metal by hammering, sometimes resulting in a stronger workpiece. Most often, a hot-forming process is used in which the temperature of the workpiece is elevated in an oven, by direct flame or by induction.
Open-die forging usually involves striking the workpiece with a hammer against an anvil: good for short-run or single-piece work.
In impression-die (or closed-die) forging, the workpiece is compressed between two die halves, such that the metal is deformed in the cavity between them. Forged pieces have outstanding grain structure and the best combination of mechanical properties.
Induction heating is a prime candidate for many forging applications. The process and economic inefficiencies of gas furnaces or flames are avoided with this unique technology which quickly and accurately delivers the required heating to the workpiece only. Additional benefits accrue since the heating can be integrated into the forging process nearer the die. With Ameritherm's modern technology, remote heat stations are placed directly into production lines for high volume rapid forging processes.
Hot forging takes place at workpiece temperatures above which recrystallization occurs. This process requires uniform through-heating. Typical part geometries are simple, often comprising of bar stock, tubular products, and sheet metal.
