With an impressive legacy spanning over three decades in the custom forging industry, we embody the spirit of a traditional forging manufacturer while consistently embracing and integrating cutting-edge techniques and state-of-the-art machinery. Our unwavering commitment to innovation and excellence drives us to evolve and enhance our capabilities, ensuring we meet and exceed the ever-changing demands of the market with pleasure and precision.
While forging stands as one of humanity's oldest metalworking techniques, it remains unparalleled in its effectiveness even today. At its essence, forging involves expertly shaping raw metal while maintaining its solid state, preventing complete melting. During this fascinating process, an operator artfully employs a mix of forming techniques such as hammering, rolling, or pressing. Despite the myriad variations of forging-each boasting unique advantages-most methods heat the workpiece to soaring temperatures to aid the crafting of these intricate shapes.
When compared to casting or other metalworking methodologies, forging produces components with outstanding physical properties, including exceptional tensile strength, all at a highly competitive price. These impressive attributes stem from transformations within the metal's grain structure. By never melting the material, forging's percussive or compressive forces coax the metal's grain to flow harmoniously with the final product's shape, resulting in components that surpass the strength of both machined and casted alternatives.
CMC Forge eliminates barriers to these forging advantages, offering clients across diverse industries a comprehensive suite of expert forging services tailored to a vast array of applications.
THE FORGING PROCESS
Forging encompasses a multitude of subtypes, each with unique steps, yet most processes adhere to a common framework.
In the realm of metal forging, two predominant techniques reign supreme: hot forging and cold forging. Both methods are distinct metal forming processes, each with its own unique characteristics, yet they both aspire to achieve similarly remarkable outcomes in their finished products.
Hot forging involves the high-temperature transformation of metals, where they are heated beyond their recrystallization point, sometimes reaching scorching temperatures of up to 2,300 degrees Fahrenheit. The primary advantage of this technique lies in the reduced energy needed to mold the metal to its desired form. This is achieved because the intense heat significantly decreases yield strength while enhancing the metal's ductility. Moreover, hot forging excels in eliminating chemical inconsistencies, ensuring a superior and consistent product.
Cold forging, on the other hand, is typically conducted at room temperature or any temperature below the metal's recrystallization point. While some metals, particularly high-carbon steel, pose challenges for cold forging due to their strength, this method boasts superior advantages in dimensional accuracy, uniformity, surface finish, and mitigation of contamination risks. Encompassing a wide array of techniques such as bending, extruding, cold drawing, and cold heading, cold forging offers greater versatility. However, this comes with a trade-off, as it demands more robust equipment and often necessitates intermediate annealing.
ADVANTAGES

Our products serve sectors such as automotive, food and dairy, machinery, medical, plumbing, irrigation, mining, petrochemical, electrical, energy, aerospace, submarine, and many others.
Renowned for creating some of the most robust manufactured parts and components, hot forging stands out among other metal manufacturing processes. We specialize in producing hot forging parts ranging from a few grams to several hundred kilograms. For those pieces requiring special surface finishes, we offer an extensive array of secondary operations including precision machining, exquisite surface treatments, and more.
Hot forging is a transformative process where metal is heated beyond its recrystallization temperature. This procedure lowers the flow stress and energy needed to mold the metal, thereby significantly enhancing the production rate (or strain rate). Hot forging not only facilitates the shaping of metal but also reduces the likelihood of fractures during the process.
Iron and its alloys are predominantly hot forged due to two pivotal reasons: #1) As work hardening continues, hard materials like steel and iron become increasingly challenging to manipulate, and #2) Opting for hot forging with subsequent heat treatment processes is more cost-effective, as metals like steel can attain enhanced strength through various processes beyond just cold working.
Typical temperatures used in hot forging include: Aluminum (Al) Alloys - 360° (680°F) to 520°C (968°F); Copper (Cu) Alloys - 700°C (1,292°F) to 800°C (1,472°F); Steel - up to 1,150°C (2,102°F)
During the intricate process of hot forging, metal is heated above its recrystallization point. This critical step ensures deformation without the risk of strain hardening. Typically, the metal is heated and then shaped in a pre-heated mold that complements its temperature. The pliability of hot metal allows for the creation of complex shapes, surpassing the capabilities of cold forging.
For superalloys with inherent low malleability, advanced processes like isothermal forging (conducted in a controlled atmosphere) are implemented to prevent oxidation. Also known as hot forging, this thermal process maintains the workpiece at its peak temperature throughout the forming stage.
To sustain this temperature, the mold is heated to either match or slightly lag the workpiece's temperature. The mold's pressure shapes the workpiece, and with the mold also at an elevated temperature, cooling at the interface is minimized. This results in improved flow properties of the metal workpiece.
