As a distinguished traditional forging manufacturer, we blend the wisdom of experience with the foresight to embrace cutting-edge techniques and state-of-the-art machinery. Our commitment is unwavering-to evolve and innovate continuously, ensuring we meet and exceed the dynamic demands of today's market with diligence and passion.
Forging, a time-honored technique in metalworking, continues to stand out as a remarkably effective method even in today's advanced industrial landscape. At its essence, forging involves the artful transformation of raw metal without reaching a liquefied state, maintaining the metal's solid form. Skilled operators employ a variety of techniques, such as hammering, rolling, and pressing, to shape the metal. Though diverse in nature, each forging variation offers distinct benefits. Typically, the process involves heating the workpiece to extremely high temperatures, making it more pliable for the shaping procedures.
When compared with casting or alternative metalworking methods, forging boasts superior physical attributes, notably an exceptional level of tensile strength, all at an enticing price point. These advantageous properties primarily arise from the modification of the metal's grain. Since the metal remains unmelted, the applied percussive or compressive forces during forging guide the grain to conform to the contours of the final product. This results in components that surpass their machined and cast counterparts in strength and durability.
CMC Forge extends these remarkable benefits to clients spanning a multitude of industries, delivering an extensive array of expertly crafted forging services that cater to a diverse range of applications.
THE INTRICACIES OF THE FORGING PROCESS
The forging process comprises various subtypes, each contributing unique steps to product formation; however, most adhere to a similar foundational framework.
The metal forming world is dominated by two titans: hot forging and cold forging. Although they are distinct processes, both hot forging and cold forging ultimately strive to achieve the same goal: transforming metal into desired shapes with precision and efficiency.
Hot forging involves heating metal beyond its recrystallization point, often reaching temperatures of up to 2,300 degrees Fahrenheit. The most alluring benefit of hot forging is the significant reduction in energy required, thanks to the diminished yield strength and enhanced ductility that come with intense heat. Furthermore, hot forged products enjoy a remarkable uniformity, as the high temperatures effectively eradicate chemical inconsistencies, resulting in superior quality outcomes.
Cold forging, on the other hand, is the art of manipulating metal at room temperature or below its recrystallization threshold. High-carbon steels and similarly robust materials can present challenges to cold forging due to their strength. Nonetheless, cold forging shines with superb dimensional accuracy, unparalleled product consistency, and an immaculate surface finish. The versatility of cold forging is impressive, incorporating techniques like bending, extruding, cold drawing, and cold heading. However, this versatility demands advanced machinery and occasionally requires intermediate anneals to achieve the desired results.

For those items requiring special surface finishes, we offer an extensive suite of secondary operations, including precise machining and expert surface finishing.
Hot forging involves the significant process of heating metal beyond its recrystallization temperature, which in turn reduces the flow stress and energy needed for metal formation, significantly boosting the production rate. This process not only simplifies the shaping of metals but also minimizes the risk of fracture, ensuring durability and precision.
Iron and its alloys are predominantly hot forged for two compelling reasons: Firstly, as work hardening progresses, it becomes increasingly challenging to manipulate hard materials like steel and iron. Secondly, economically speaking, hot forging metals such as steel, followed by heat treatment, strengthens them through various processes, offering a cost-effective alternative to cold working.
The average temperatures for hot forging different metals include: Aluminum (Al) Alloys at 360° (680°F) to 520°C (968°F); Copper (Cu) Alloys between 700°C (1,292°F) and 800°C (1,472°F); and Steel which can be forged up to 1,150°C (2,102°F), making it adaptable to diverse applications.
During the meticulous process of hot forging, the metal is heated above its recrystallization point. This crucial step ensures the metal avoids strain hardening as it is plastically deformed. The process typically involves heating the metal above its recrystallization point and then precisely comminuting it into a mold, which can be heated as needed, allowing the creation of complex shapes unattainable by cold forging.
For superalloys, recognized for their low malleability, isothermal forging is employed to prevent oxidation. Known also as hot forging, this controlled thermal process ensures the workpiece remains at its optimal temperature throughout, enhancing its structural integrity.
Maintaining the workpiece's temperature is achieved by heating the mold to an elevated or slightly lower temperature. This careful control prevents cooling between mold interfaces, enhancing the metal's flow properties, ensuring the final product's superior quality and precision.
