Forging, while an ancient art, continues to be a pillar of metalworking excellence today. At its essence, forging involves the transformation of raw metal without reaching its melting point, preserving its solid state. This unique process is a symphony of shaping techniques like hammering, rolling, or pressing. Each method, equipped with its own distinct benefits, often involves elevating the workpiece to high temperatures, making the metal malleable for these precision shaping endeavors.
Forging stands superior to casting and other techniques, offering unmatched physical properties, notably high tensile strength, at a competitive price. This superiority arises from the transformation of the metal's grain structure. As the material remains unmelted, the applied forces during forging align the grain with the product's shape, resulting in components with remarkable strength, surpassing machined or casted versions.
CMC Forge empowers industries by translating these forging benefits into reality, providing a comprehensive suite of forging services tailored to diverse application needs.
THE FORGING PROCESS
The forging process features a variety of subtypes, each contributing its own steps to the overall procedure. Despite these variations, a fundamental outline guides most forging operations.
Within the realm of metal forming processes, two prominent techniques stand out: hot forging and cold forging. Both hot forging and cold forging are distinct methodologies, yet they both aim to achieve similar outcomes in shaping metals.
Hot forging is a fascinating process where metals are heated beyond their recrystallization temperature, potentially reaching up to a scorching 2,300 degrees Fahrenheit. The key advantage of this method lies in the reduced energy necessary for proper metal shaping, as the intense heat diminishes yield strength while enhancing ductility. Additionally, hot forged products boast improved uniformity due to the elimination of chemical inconsistencies.
Cold forging is predominantly associated with shaping metals at ambient, room temperatures, though it technically includes any temperature below recrystallization levels. While high-carbon steel, for instance, often proves too robust for cold forging, this technique excels in providing superior dimensional control, enhanced product uniformity, and a flawless surface finish. Cold forging is versatile, encompassing methods like bending, extruding, cold drawing, and cold heading. However, this versatility requires more powerful machinery and might necessitate intermediate annealing processes.

Our expertise spans from lightweight a few grams to massive components weighing several hundred kilograms. For those specialized finishes, we provide a comprehensive suite of secondary operations, including precision machining and surface finishing, to meet all your specific requirements.
Hot forging is a transformative process that involves heating metal beyond its recrystallization temperature, drastically lowering the flow stress and energy needed for shaping. This method significantly enhances production efficiency and allows for seamless metal shaping with a reduced risk of fractures.
Iron and its alloys are primarily hot forged due to two compelling reasons: Firstly, avoiding work hardening in tough materials like steel and iron is crucial. Secondly, hot forging is a cost-effective option, as metals like steel can be further fortified through subsequent heat treatments, making it preferable over solely cold-working processes.
Hot forging operates at distinct temperatures for various metals: Aluminum (Al) Alloys are processed between 360° (680°F) and 520°C (968°F); Copper (Cu) Alloys at 700°C (1,292°F) to 800°C (1,472°F); Steel reaches up to a scorching 1,150°C (2,102°F).
In the dynamic process of hot forging, metals are heated beyond their recrystallization threshold to prevent strain hardening during shaping. The metal, now highly pliable, is then placed in molds that may also be heated. This allows for intricate and complex designs that cold forging simply can't achieve.
For superalloys with limited malleability, innovative processes like isothermal forging are employed, maintaining a controlled atmosphere to prevent oxidation. Isothermal forging, synonymous with hot forging, continuously retains the workpiece at its optimum temperature throughout the entire shaping process.
To maintain optimal conditions during hot forging, molds are heated to match or slightly trail the workpiece temperature. This heat synchronization prevents cooling at the mold interfaces, enhancing the metal's flow characteristics and ensuring a superior end product.
