Our mission is to continually develop and enhance our capabilities to meet and exceed the dynamic demands of the market, ensuring satisfaction and pioneering excellence for our clients.
Forging, an age-old metalworking technique, continues to excel as a remarkably effective method even today. At its essence, forging involves shaping raw metal without completely melting it, keeping it solid while an operator skillfully applies techniques such as hammering, rolling, or pressing. Though numerous forging variations exist, each with unique advantages, the common thread is heating the workpiece to high temperatures, facilitating the shaping process with remarkable precision.
When compared to casting and other metalworking methods, forging stands out for delivering superior physical attributes, notably a high tensile strength, all while being cost-effective. These advantages stem from alterations in the metal's grain; since the metal isn't melted, the applied percussive or compressive forces during forging guide the grain to follow the intended flow of the finished piece. This results in components that are significantly stronger than their machined or casted counterparts.
CMC Forge is dedicated to bringing these exceptional advantages to clients across various industries by offering an extensive suite of expert forging services tailored to a wide array of applications.
THE INTRICACIES OF THE FORGING PROCESS
The forging process encompasses numerous subtypes, with specific steps that may vary depending on the product. Generally, however, most forging operations adhere to a similar foundational outline.
In the fascinating world of metal forming, two stalwart techniques reign supreme: hot forging and cold forging. These extraordinary processes, while differing in their methodologies, ultimately deliver remarkably similar results, shaping and refining metals to meet the highest standards.
Hot forging is a process that involves heating metal beyond its recrystallization threshold, sometimes reaching a scorching 2,300 degrees Fahrenheit. The primary allure of hot forging lies in its ability to reduce the energy needed to form metals, thanks to the high-temperature's effect of lowering yield strength and enhancing ductility. Furthermore, hot forging eradicates chemical inconsistencies, fostering products of superb quality.
Cold forging, although it typically takes place at ambient temperatures, can occur at any point below a metal's recrystallization temperature. This method often meets its match with high-carbon steels due to their formidable strength, yet it excels in areas like dimensional precision, uniformity, surface finish, and contamination control. Cold forging offers a versatile palette of techniques-bending, extruding, cold drawing, and cold heading-all contributing to its adaptability. However, these advantages demand more robust equipment and sometimes intermediate anneals, adding a layer of complexity and cost.

Hot forging involves elevating the metal above its recrystallization temperature, allowing for reduced flow stress and energy requirements during formation. This methodology enhances production rates and transforms the metal into a form that's easier to shape, minimizing fracture risks.
Iron and its alloys are predominantly hot forged for compelling reasons: #1) Avoiding the challenges of work hardening in tough materials like steel and iron, and #2) Economically leveraging the potential of post-hot forging heat treatments, which further fortify metals beyond cold working alone.
Typical hot forging temperatures are as follows: Aluminum (Al) Alloys from 360°C (680°F) to 520°C (968°F); Copper (Cu) Alloys range between 700°C (1,292°F) and 800°C (1,472°F); Steel can reach up to 1,150°C (2,102°F).
The hot forging process elevates the metal's temperature beyond its recrystallization threshold, essential to prevent strain hardening while deforming. This involves heating the metal above this point and shaping it in molds, which may also be heated, allowing for the creation of intricate designs unattainable through cold forging.
For superalloys with limited malleability, isothermal forging in controlled atmospheres is employed to avert oxidation. This variant of hot forging ensures the workpiece remains at peak temperature throughout, optimizing formability.
Achieving optimal temperatures involves heating the mold close to or slightly below the workpiece temperature. This alignment prevents premature cooling of the workpiece at the mold interfaces, significantly enhancing the metal's flow characteristics.
