As a time-honored forging manufacturer, we not only draw from the rich experiences of others but are also deeply committed to incorporating cutting-edge techniques and state-of-the-art machinery. We are dedicated to evolving and enhancing our capabilities to seamlessly align with and fulfill the ever-changing demands of the market.
Although forging is one of the oldest methods of metalworking, it remains one of the most effective to this day. At its core, forging is the process of forming raw metal without allowing the material to completely melt. The metal remains in a solid state while an operator performs any combination of forming techniques such as hammering, rolling, or pressing. While there are many variations of forging-each with their own distinct advantages-most involve heating the workpiece to very high temperatures to facilitate these shaping processes.
In comparison to casting or other metalworking techniques, forging stands out by offering the most desirable physical characteristics, including an exceptional degree of tensile strength, all at a very attractive price-point. These advantageous qualities mainly result from alterations to the metal's grain. Since the material is never melted, the percussive or compressive forces applied during forging compel the grain to follow the flow of the finished product. This results in components that are significantly stronger than their machined and cast counterparts.
CMC Forge ensures these remarkable benefits are universally accessible to clients across diverse industries, delivering a comprehensive array of skilled forging services that cater to the needs of various applications.
THE FORGING PROCESS
There are many subtypes of the broader forging process, so the exact steps involved in forming a product may vary. Most procedures, however, will follow the same general outline.
Forging is a dynamic field with two predominant methods: hot forging and cold forging. Both processes skillfully shape metals into desired forms, each offering unique advantages while achieving similar outcomes.
In hot forging, metals are meticulously heated beyond their recrystallization temperatures, sometimes reaching up to a scorching 2,300 degrees Fahrenheit. This intense heat dramatically reduces the energy needed to mold the metal, as it lowers yield strength and enhances ductility. Hot forging is renowned for eradicating chemical inconsistencies, resulting in superior product integrity.
Cold forging, on the other hand, is performed at or near room temperature, though it can be done at any temperature below the recrystallization point. While metals like high-carbon steel may resist this method due to their inherent strength, cold forging excels in precision, delivering impeccable dimensional control, uniformity, surface finish, and minimizing contamination. It involves a variety of techniques such as bending, extruding, cold drawing, and cold heading. The versatility of cold forging, however, demands robust machinery and occasionally necessitates intermediate annealing stages.
ADVANTAGES

Our expertise ensures that each part we produce is crafted to perfection, meeting the diverse needs of our clientele with precision and reliability.
Renowned for its strength and durability, hot forging produces the most robust parts compared to other metal manufacturing methods. We specialize in crafting components ranging from a few grams to several hundred kilograms. For those demanding distinct surface finishes, we offer a wide spectrum of secondary operations including meticulous machining and finishing touches that elevate both function and form.
Hot forging involves heating metal beyond its recrystallization temperature, a technique that lowers the stress and energy required for shaping, thereby boosting production rates. This process not only facilitates the molding of metal into intricate forms but also minimizes the risk of fractures, ensuring a seamless blend of flexibility and integrity.
Iron and its alloys are predominantly hot forged for two pivotal reasons: #1) As work hardening advances, tough materials like steel and iron become more formidable to manipulate; #2) Hot forging presents a cost-effective strategy, enabling subsequent heat treatments that enhance the metal's strength without exclusive reliance on cold working processes.
Typical hot forging temperatures include: Aluminum (Al) Alloys - 360° (680°F) to 520°C (968°F); Copper (Cu) Alloys - 700°C (1 292°F) - 800°C (1 472°F); Steel - up to 1 150°C (2 102°F). These temperatures ensure optimal forming conditions for diverse materials, enhancing their performance and longevity.
Hot forging involves heating the metal above its recrystallization point. This crucial step prevents strain hardening during deformation. The process typically includes heating the metal and molding it into a pre-heated mold. The increased malleability of the hot metal allows for the creation of complex shapes with ease, elevating the possibilities beyond those of cold forging.
For superalloys with low malleability, isothermal forging is employed to prevent oxidation. Known as hot forging, this thermal process maintains the workpiece at peak temperature, ensuring uniformity and strength throughout the forming procedure.
Temperature control is achieved by heating the mold to a level that matches or slightly undercuts the workpiece's temperature. This eliminates cooling at the mold interface, enhancing the flow characteristics and resulting in superior quality and performance of the forged part.
