Forging: a time-honored yet extraordinary metalworking technique that has not only endured but excelled through the ages. At its core, forging is the art of shaping raw metal in its solid state, skillfully avoiding the complete melting of the material. Master craftsmen employ a variety of sophisticated techniques-such as hammering, rolling, or pressing-to expertly mold the metal. Although a plethora of forging variations exists, each offering distinct advantages, the fundamental principle remains consistent: meticulously heating the metal workpiece to elevated temperatures to facilitate optimal shaping.
Forging stands unmatched when juxtaposed with casting or other metalworking techniques, offering unparalleled physical properties, notably exceptional tensile strength, all while maintaining cost-effectiveness. This superiority is primarily attributed to the transformation in the metal's grain structure. By circumventing full melting, forging applies strategic percussive or compressive forces that guide the grain to seamlessly align with the contours of the final product. Consequently, this process yields components of significantly greater strength than those crafted through machining or casting.
CMC Forge is passionately committed to making the remarkable advantages of forging accessible across a multitude of industries. We proudly offer an extensive array of expert forging services, each meticulously tailored to meet the diverse demands of a wide range of applications.
THE INTRICATE FORGING PROCESS
The forging process is a tapestry of subtypes, each with its own unique steps that may vary. Despite these variations, most procedures adhere to a shared foundational blueprint.
In the sophisticated realm of metal forming, two predominant methods captivate the industry - hot forging and cold forging. Although distinct in their execution, these processes converge remarkably to deliver products that meet exemplary standards of quality and application versatility.
Hot forging involves the meticulous art of heating metal to temperatures soaring beyond its recrystallization point, at times reaching an astounding 2,300 degrees Fahrenheit. This celebrated method reduces the energy required to shape metal due to the intense heat, which diminishes yield strength and enhances ductility. The process eradicates chemical inconsistencies, culminating in superior product quality that stands the test of time.
In contrast, cold forging is an innovative process performed at room temperature or any point below the metal's recrystallization temperature. While some metals, notably high-carbon steel, are too robust for cold forging, this method excels in delivering unparalleled dimensional precision, uniformity, and surface finish while minimizing contamination. Encompassing a versatile array of techniques such as bending, extruding, cold drawing, and cold heading, cold forging's broader application range requires more robust equipment and potentially intermediate anneals, which contribute to higher operational costs.
ADVANTAGES

We proudly serve a multitude of industries, including automotive, food dairy, machinery, medical, plumbing, mining, petrochemical, electrical, energy, aerospace, and submarine. Our commitment is to deliver unparalleled performance and steadfast reliability tailored for each sector's unique demands.
Hot forging stands as a pinnacle manufacturing technique, known for crafting enduring and robust parts and components that surpass other metal manufacturing methods. Our expertise in producing precision hot forging parts spans a wide range, from mere grams to hefty hundreds of kilograms. To meet diverse needs for special surface finishes, we provide an expansive selection of secondary operations, featuring state-of-the-art machining and surface finishing services, meticulously curated to meet exact specifications.
Hot forging is a transformative process where metal is heated beyond its recrystallization threshold, effectively reducing the required flow stress and energy for shaping. This method significantly simplifies metal forming, mitigates fracture risks, boosts production efficiency, and delivers superior quality results.
Predominantly, iron and its alloys are subjected to hot forging for two main reasons: Firstly, as work hardening advances, materials like steel and iron become increasingly resistant to manipulation. Secondly, hot forging offers an economical solution, allowing for subsequent heat treatments that further amplify their strength through varied processes beyond the capabilities of cold working alone.
Typical hot forging temperatures include: Aluminum (Al) Alloys - 360°C (680°F) to 520°C (968°F); Copper (Cu) Alloys - 700°C (1,292°F) to 800°C (1,472°F); Steel - reaching up to 1,150°C (2,102°F).
The hot forging process entails heating metal beyond its recrystallization temperature to avoid strain hardening during deformation. This involves heating and pressing the metal into a mold, which may also be heated as required. Such elevated temperatures permit effortless 'movement' of the metal, enabling manufacturers to craft intricate designs that cold forging cannot achieve.
For superalloys, recognized for their limited malleability, isothermal forging is deployed within a controlled atmosphere to prevent oxidation. This advanced hot forging technique sustains the workpiece at an optimum temperature throughout, ensuring premium quality.
Maintaining the mold at a high or slightly lower temperature than the workpiece is crucial. This strategy eliminates premature cooling at the mold-workpiece interface, thus enhancing the metal's flow characteristics and ensuring flawless part manufacturing.
