IN THE BEGINNING
Forged metal work has a romance and history that goes back to Vulcan's forge,
conjuring up images of medieval craftsmen setting their anvils ringing with
hammers and bellows.
Hot forging as a method of shaping heated metal by compression is the oldest known metal working process. Prehistoric man realised that he could heat metal and shape it by hitting it with a rock and as time evolved, forging became a process that man used to shape tools, implements, blades and other items made of both nonferrous and ferrous metals. This activity became known as blacksmithing.
The blacksmith was immortalised as the true hero of early villages as he crafted armour for the soldiers, tools for the local artisans, metal soil tilling implements for farmers, and tools and other metal devices for homeowners and trades people of the time.
TODAY'S HOT FORGING PROCESS
During the hot forging process, a metal work piece is plastically
deformed by pressing, squeezing, or hammering forces, usually at temperatures
ranging from ambient to 1,500 degrees C, so that it approaches its maximum theoretical
density and the upper limits of the material's potential strength. The properties
of the worked metal can be greatly enhanced by selecting the proper types and
sequence of operations. The controlled process of deformation that takes place
imparts exceptional metallurgical soundness and mechanical properties to the
forging: structural integrity, impact strength, fracture toughness, fatigue
life and uniformity.
Technological advances in forging processes provide substantial advantages over other competing manufacturing processes, such as higher strength, superior internal integrity, more consistent and higher metallurgical properties. We have introduced sophisticated control systems and advanced processing equipment to produce products with greater uniformity, to extremely tight dimensional tolerances, in time to meet our customers' stringent delivery schedules.
Modern day forging imparts advantages that few processes can duplicate, and we consistently strive to improve these advantages:
Forgings are used in high performance, high strength, and high reliability applications where tension, stress, load, and human safety are critical considerations. They are also used in a wide range of demanding environments, including highly corrosive and extreme pressures and temperatures.
