Located a mere 200 kilometers from the bustling metropolis of Beijing, our factory boasts over three decades of expertise in the custom forging industry. As a stalwart in traditional forging, we pride ourselves on blending time-honored craftsmanship with cutting-edge techniques and machinery. Our dedication to continuous development and improvement ensures that we not only meet but exceed market demands, delivering unparalleled satisfaction to our valued clients.
Forging, one of the most time-honored techniques in metalworking history, continues to be an unparalleled method for crafting metals today. At its essence, forging involves the expert formation of raw metal, skillfully avoiding complete melting of the material. The metal remains solid while a seasoned operator employs various transformative techniques such as hammering, rolling, or pressing. Despite the myriad variations of forging-each offering its unique advantages-most involve elevating the workpiece to exceedingly high temperatures, enabling seamless shaping processes.
When contrasted with casting or alternative metalworking methods, forging delivers exceptional physical attributes, notably a superior tensile strength, all while being cost-effective. These advantageous properties stem primarily from transformations in the metal's grain structure. As the material remains solid, the dynamic percussive or compressive forces applied during forging guide the grain structure to follow the shape of the finished product. This produces components possessing robust strength, surpassing those created through machining or casting.
CMC Forge brings these compelling advantages to clients across diverse industries, providing an extensive array of proficient forging services tailored to meet the specific requirements of countless applications.
THE INTRICACIES OF THE FORGING PROCESS
The broader forging process encompasses numerous subtypes, meaning the precise steps in product formation can vary. However, most procedures adhere to a universal framework.
In the world of metal crafting, two dominant methods emerge: hot forging and cold forging. These distinct processes, each with their own unique techniques, ultimately aim to achieve similar end results in shaping metal to perfection.
Hot forging is an art that involves heating metal beyond its recrystallization temperature, often soaring to temperatures as high as 2,300 degrees Fahrenheit. This intense heat significantly reduces the energy required to mold the metal, making it more pliable and easier to shape. The primary advantage of this process is the liberal reduction in yield strength and enhanced ductility, allowing for more intricate designs and shapes. Additionally, hot forging effectively eradicates chemical inconsistencies, resulting in superior integrity of the final product.
Cold forging, on the other hand, operates predominantly at room temperature or below recrystallization levels. While it may not be suitable for all metals, particularly those like high-carbon steel due to their inherent strength, cold forging excels in precision. It offers unparalleled dimensional accuracy, product uniformity, surface finesse, and diminished contamination. The process encompasses a variety of methods such as bending, extruding, cold drawing, and cold heading. Nonetheless, this versatility demands more powerful machinery and may necessitate intermediate anneals to achieve the desired outcome.
ADVANTAGES

Our superior quality products are indispensable in sectors such as automotive, food dairy, machinery, medical, plumbing, watering, mining, petrochemical, electrical, energy, aerospace, submarine, and many others.
Hot forging is renowned for its ability to produce exceptionally strong manufactured parts and components when compared to other metal manufacturing processes. We excel in creating hot forging parts and components ranging from a few grams to over several hundred kilograms. For those with special surface finish requirements, we offer an extensive array of secondary operations including machining and surface finishing, ensuring your products meet the highest standards.
Hot forging involves heating metal above its recrystallization temperature, a process that effectively reduces the flow stress and energy required for metal formation. This results in enhanced production rates (or strain rate). Hot forging facilitates easier shaping of the metal while minimizing the likelihood of fracture, making it a preferred method in various industries.
Iron and its alloys are predominantly hot forged for two primary reasons: #1) To manage work hardening in hard materials such as steel and iron, which become increasingly challenging to manipulate, and #2) Hot forging is a cost-effective method that allows for subsequent heat treatment processes. Metals like steel benefit from additional strengthening processes beyond just cold working, underlining the economic advantage of hot forging.
Typical temperatures for hot forging 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)
The hot forging process involves reaching temperatures above the recrystallization point of the metal being formed. This crucial step ensures that strain hardening during deformation is avoided. Typically, the metal is heated above its recrystallization temperature and then shaped in a mold, which can also be heated as necessary. This high temperature allows for the easy 'movement' of metal, enabling manufacturers to craft more complex shapes than those possible with cold forging.
For superalloys with low malleability, isothermal forging (deformation in a controlled atmosphere) is employed to prevent oxidation. Isothermal forging, synonymous with hot forging, is a thermal processing technique that maintains the workpiece at its peak temperature throughout the forming process.
The maintenance of temperature is achieved by heating the mold to an elevated or slightly lower temperature than the workpiece. The application of force by the mold forms the workpiece, while the mold's elevated temperature prevents cooling at the interfaces, thus enhancing the metal's flow properties.
