Forging, a timeless and highly effective metalworking process, continues to thrive as a cornerstone of engineering excellence. At its core, forging is the art of transforming raw metal while preserving its solid form, skillfully avoiding full melting. Master craftsmen harness various forming techniques-such as hammering, rolling, or pressing-to expertly shape the metal. While numerous forging methods exist, each with distinct advantages, the unifying principle remains: elevating the metal workpiece to high temperatures to facilitate seamless shaping.
Forging stands unrivaled when compared to casting and other metalworking methods, offering unparalleled physical attributes like remarkable tensile strength, all while maintaining cost efficiency. This superiority comes from the transformation in the metal's grain structure. By forgoing full melting, forging employs percussive or compressive forces to guide the grain, aligning it with the shape of the final product. This meticulous process yields components significantly stronger than those derived from machining or casting methods.
CMC Forge is committed to democratizing the benefits of forging across a wide array of industries. We provide a comprehensive suite of expert forging services, meticulously crafted to meet the diverse needs of various applications and industries.
THE FORGING PROCESS
The forging process is a multifaceted practice, comprising numerous subtypes, each with its own unique steps. Despite these variations, the majority of procedures adhere to a universal foundational outline.
In the fascinating domain of metal forming, two distinguished methods reign supreme - hot forging and cold forging. While these techniques differ in their execution, they converge remarkably to produce outcomes of comparable excellence in terms of product quality and versatility of application.
Hot forging is a process that involves heating metal to extraordinary temperatures, often soaring above its recrystallization point, sometimes reaching an astonishing 2,300 degrees Fahrenheit. This technique is acclaimed for its ability to significantly reduce the energy required to mold the metal, owing to the intense heat, which diminishes yield strength and elevates ductility. Moreover, hot forging effectively eradicates chemical inconsistencies, culminating in a product of superior quality.
Conversely, cold forging is conducted at room temperature or below the metal's recrystallization threshold. While some metals, especially high-carbon steel, exhibit a strength that renders cold forging impractical, it excels in delivering unparalleled dimensional precision, uniformity, and an exquisite surface finish, while minimizing contamination. Encompassing a range of techniques such as bending, extruding, cold drawing, and cold heading, cold forging's extensive application potential necessitates more durable equipment and sometimes intermediate anneals, which can lead to increased operational costs.
ADVANTAGES

Our expert capabilities cover crafting precision hot forging parts, from a delicate few grams to substantial several hundred kilograms. For those with a discerning eye for detail, we provide a wide array of secondary operations, including state-of-the-art machining and surface finishing services, all meticulously tailored to your specifications.
Hot forging is a transformative process that involves heating metal beyond its recrystallization temperature. This reduces the flow stress and energy necessary for metal formation, enhancing the ease of shaping metals while significantly lowering the risk of fractures. This results in accelerated production efficiency and guarantees superior quality results.
Iron and its alloys are mainly hot forged due to two key reasons: first, as work hardening occurs, materials like steel and iron become increasingly difficult to manipulate. Second, hot forging these materials provides a cost-effective alternative, permitting subsequent heat treatments that further fortify their strength with various processes, extending beyond mere cold working.
Typical hot forging temperatures include: Aluminum (Al) Alloys range from 360°C (680°F) to 520°C (968°F); Copper (Cu) Alloys from 700°C (1,292°F) to 800°C (1,472°F); Steel can soar up to 1,150°C (2,102°F).
In the hot forging process, metal is elevated above its recrystallization temperature to avert strain hardening during deformation. This involves meticulously heating the metal and shaping it into a mold, which can also be heated as required. The elevated temperatures allow the metal to be effortlessly 'moved,' enabling manufacturers to create intricate designs that are otherwise unachievable through cold forging techniques.
For superalloys, known for their reduced malleability, isothermal forging is utilized in a controlled atmosphere to prevent oxidation. This specialized form of hot forging maintains the workpiece at peak temperature throughout the entire process, ensuring exceptional quality.
Maintaining the mold at a high or slightly lower temperature than the workpiece is crucial. This approach prevents premature cooling at the mold-workpiece interface, enhancing the metal's flow properties and ensuring seamless and flawless manufacturing of parts.
