Our rich heritage as a traditional forging manufacturer is complemented by our visionary approach to embrace cutting-edge techniques and state-of-the-art machinery. We are passionately committed to evolving and enhancing our capabilities to meet and surpass market demands, ensuring we remain at the forefront of the forging industry.
Despite its origins dating back centuries, forging remains one of the most potent and reliable metalworking techniques available today. Essentially, forging is a meticulous process where raw metal is adeptly shaped without allowing complete melting. The metal retains its solid form as skilled operators employ various techniques such as hammering, rolling, and pressing to achieve the desired shape. While numerous forging methods exist, each with unique advantages, most involve elevating the metal workpiece to substantial temperatures, enabling the seamless execution of these transformative processes.
When juxtaposed with casting or alternative metalworking techniques, forging outshines by offering exceptional physical attributes, notably a remarkable level of tensile strength-all at a cost-effective price. These superior qualities stem primarily from the ingenious manipulation of the metal's grain structure. By avoiding the melting phase, the powerful percussive and compressive forces during forging guide the grain's alignment to enhance the final product's robustness. This results in components that boast significantly greater strength compared to their machined or casted counterparts.
At CMC Forge, we unlock these exceptional advantages for clients across a broad spectrum of industries, providing an extensive array of expert forging services tailored to meet the diverse demands of countless applications.
Understanding the Forging Process
The forging process encompasses a variety of subtypes, each with its specific steps for crafting a product. Nonetheless, most procedures adhere to a similar foundational framework.
Discover the two principal forging methodologies: hot forging and cold forging. While both processes are distinct, they serve the purpose of transforming metal into desired forms with exceptional results.
Hot forging elevates metals beyond their recrystallization thresholds, reaching up to an intense 2,300 degrees Fahrenheit. The standout advantage of hot forging is the notable reduction in the energy required to shape the metal effectively. This process is favored due to the reduced yield strength and enhanced ductility that excessive heat provides. Additionally, hot forging ensures the removal of chemical inconsistencies, resulting in superior quality products.
Cold forging predominantly involves working with metals at ambient temperatures, keeping them below the recrystallization point. However, high-carbon steel and other robust metals often exceed the limitations of cold forging. Despite this, cold forging excels in achieving precise dimensional control, ensuring uniformity of products, delivering superior surface finishes, and minimizing contamination. The process encompasses a plethora of techniques, such as bending, extruding, cold drawing, and cold heading. Yet, its versatility demands stronger equipment and may necessitate intermediate anneals, adding to the complexity.
ADVANTAGES
We deliver exceptional quality hot forging parts and components, expertly crafted to serve a multitude of industries. From automotive and food dairy to machinery, medical, plumbing, watering, mining, petrochemical, electrical, energy, aerospace, submarine, and beyond, our products meet the robust demands of diverse applications.
Regarded as one of the premier methods for producing ultra-strong manufactured parts and components, hot forging stands unparalleled. Our capabilities range from creating lightweight pieces weighing mere grams to substantial components exceeding several hundred kilograms. For those parts requiring meticulous surface finishes, we offer an extensive array of secondary operations, including precision machining and advanced surface finishing techniques.
Hot forging involves heating metal above its recrystallization temperature. This essential step reduces the flow stress and energy needed to form the metal, significantly boosting the production rate. This method not only simplifies shaping the metal but also minimizes the risk of fracturing, ensuring durability and precision.
Iron and its alloys are predominantly hot forged for two compelling reasons: Firstly, work hardening increases difficulty in processing materials like steel and iron. Secondly, post-hot forging, metals like steel can be economically strengthened with heat treatments, offering a cost-effective alternative to cold working processes.
Typical hot forging temperatures include: Aluminum (Al) Alloys - ranging from 360°C (680°F) to 520°C (968°F); Copper (Cu) Alloys - spanning 700°C (1,292°F) to 800°C (1,472°F); and Steel - reaching up to 1,150°C (2,102°F).
In hot forging, metal is heated beyond its recrystallization temperature, pivotal for preventing strain hardening. This process involves elevating the metal's temperature and shaping it within a mold, which may also be heated. The pliability of hot metal facilitates the crafting of intricate shapes, surpassing the capabilities of cold forging.
For superalloys, limited in malleability, isothermal forging is employed. This process, also termed hot forging, entails forming the workpiece in a controlled, high-temperature environment to prevent oxidation, maintaining optimal temperature throughout.
Temperature regulation is achieved by heating the mold to a level consistent with or slightly cooler than the workpiece. This consistency in temperature prevents cooling between the mold interfaces, enhancing the metal's flow properties and ensuring superior formation.
