With an impressive legacy of over 30 years in the custom forging industry, our factory stands as a testament to tradition and innovation. As a quintessential forging manufacturer, we not only assimilate the valuable experiences from our peers but also prioritize the integration of cutting-edge techniques and state-of-the-art machinery. We are passionately committed to evolving and enhancing our capabilities to meet and exceed the dynamic demands of the market, ensuring client satisfaction at every turn.
As one of the oldest and most revered metalworking techniques, forging continues to stand the test of time due to its unparalleled effectiveness. Fundamentally, forging is the art of shaping raw metal while keeping it in a solid state, avoiding complete liquefaction. Through an array of dynamic methods such as hammering, rolling, or pressing, an operator masterfully molds the metal. Despite the numerous variations, each with unique advantages, most forging processes involve elevating the workpiece to exceedingly high temperatures, making it pliable for exquisite shaping.
Forging triumphs over casting and other metalworking methods, producing components with exceptional physical properties, especially remarkable tensile strength, all at a cost-effective price. This supremacy arises from the transformation of the metal's grain structure. Forged materials, untouched by melting, undergo powerful percussive or compressive influences, aligning the grain along the product's contours. This results in components of superior strength and resilience compared to their machined or cast counterparts.
CMC Forge expertly delivers these forging benefits to diverse industries, providing an extensive array of precision forging services tailored to a wide spectrum of applications.
THE FORGING PROCESS
The forging process encompasses a variety of subtypes, causing the steps to vary depending on the specific product requirements. Nevertheless, a common sequence underlies most procedures.
Forging processes are broadly categorized into two types: hot forging and cold forging. Each employs distinct methodologies to transform metals, ultimately achieving comparable end results.
Hot forging involves heating metals beyond their recrystallization temperature-sometimes reaching a scorching 2,300 degrees Fahrenheit. This method's standout advantage lies in its reduced energy consumption for shaping metals, as high temperatures lower yield strength and enhance ductility. Additionally, hot forging effectively eradicates chemical inconsistencies, ensuring a more uniform product.
Cold forging, on the other hand, operates largely at ambient temperatures, though it can be applied at any point below the metal's recrystallization threshold. Certain metals, especially high-carbon steels, prove too robust for cold forging. Despite this limitation, cold forging excels in delivering superior dimensional precision, uniformity, surface quality, and minimized contamination. It includes a suite of versatile techniques such as bending, extruding, cold drawing, and cold heading. However, this adaptability requires more robust equipment and may necessitate intermediate annealing steps.
KEY ADVANTAGES

We confidently manufacture hot forging parts and components ranging from a few grams to several hundred kilograms. For those parts requiring special surface finishes, we provide a comprehensive selection of secondary operations, including precise machining and expert surface finishing.
Hot forging is an extraordinary process where metal is heated beyond its recrystallization temperature. This elevation in temperature lowers the flow stress and energy needed to shape the metal, significantly elevating production rates. The process not only facilitates easier shaping but also reduces the likelihood of metal fractures, ensuring durability.
Iron and its alloys are predominantly hot forged for two compelling reasons: #1) To counteract work hardening, as hard materials like steel and iron can become increasingly challenging to manipulate. #2) Hot forging steel is more economical, followed by subsequent heat treatment processes. Steel can be fortified through diverse methods, not limited to cold working alone.
Typical temperatures for hot forging are as follows: Aluminum (Al) Alloys - between 360°C (680°F) and 520°C (968°F); Copper (Cu) Alloys - from 700°C (1,292°F) to 800°C (1,472°F); Steel - can reach up to 1,150°C (2,102°F)
Hot forging involves elevating metal temperatures above their recrystallization threshold. This crucial step prevents strain hardening during metal deformation. The process encompasses heating the metal above its recrystallization point and expertly molding it, often within a heated mold. This heat-driven method allows for crafting complex shapes, surpassing the capabilities of cold forging.
For superalloys displaying low malleability, specialized processes like isothermal forging are utilized to prevent oxidation. Isothermal forging, synonymous with hot forging, involves forming the workpiece at peak temperatures within a controlled atmosphere, ensuring optimal results.
The sustained temperature is achieved by heating the mold to an elevated or slightly lower temperature than the workpiece. The mold applies force to shape the workpiece, and the elevated mold temperature prevents cooling during contact, enhancing the metal's flow properties.
