Forging, an age-old technique of metalworking, stands the test of time as one of the most effective and enduring methods. At its essence, forging is an artful process where raw metal is shaped without reaching its melting point, allowing it to remain in a solid state. This method involves skilled techniques such as hammering, rolling, or pressing, each adding a unique touch to the material. While numerous forging variations exist, each with its distinct advantages, a common thread is the heating of the workpiece to remarkably high temperatures, facilitating the elegant shaping of the metal.
In the realm of metalworking, forging is unmatched, offering unparalleled physical characteristics like exceptional tensile strength at a competitive price. These extraordinary properties stem from the transformation of the metal's grain structure. As the material remains solid, the percussive or compressive forces applied during forging guide the grain to align with the flow of the finished product. This results in components that are significantly stronger than those created through machining or casting processes.
CMC Forge brings the superior benefits of forging to a variety of industries, providing a comprehensive suite of expert forging services tailored to diverse applications. Our commitment ensures that clients across sectors can access the precision and strength that forging imparts.
UNVEILING THE FORGING PROCESS
The world of forging boasts numerous subtypes, each with unique steps tailored to the final product's needs. However, most processes adhere to a core sequence of steps.
When exploring the fascinating world of metalcraft, two dominant techniques stand out: hot forging and cold forging. Despite their differing processes, both methods ultimately aim to achieve similar high-quality results in metal forming.
Hot forging is an art that involves heating metal beyond its recrystallization threshold, sometimes reaching searing temperatures of up to 2,300°F. This intense heat serves a purpose - it significantly reduces the energy needed for shaping the metal, as it lowers yield strength and enhances ductility. Additionally, hot forging achieves a level of metallurgical purity by eradicating chemical inconsistencies.
Cold forging, in contrast, operates predominantly at ambient conditions, or below the metal's recrystallization point. While metals like carbon-rich steel are often too robust for cold forging, this method excels in precision. It offers superior dimensional accuracy, product consistency, and surface finish, albeit requiring more powerful machinery and occasional intermediary anneals. Cold forging's techniques are diverse, encompassing bending, extruding, cold drawing, and cold heading.
ADVANTAGES

We cater to a diverse array of industries including automotive, food and dairy, machinery, medical, plumbing, agriculture, mining, petrochemical, electrical, energy, aerospace, and submarine applications, ensuring our components excel in any environment.
Renowned for producing some of the strongest parts available, hot forging surpasses other metal manufacturing methods. We expertly craft hot forged parts ranging from a few grams to several hundred kilograms. For those requiring specialized surface finishes, we offer an extensive suite of secondary operations including precision machining and advanced surface treatments.
Hot forging involves heating metal above its recrystallization temperature, significantly reducing the energy and stress needed for optimal shaping. This process not only enhances production efficiency but also improves the malleability of the metal, reducing the risk of fractures.
Iron and its alloys typically undergo hot forging for two significant reasons: #1) As work hardening progresses, it becomes increasingly challenging to manipulate hard materials like steel and iron, and #2) It is cost-effective to hot forge metals such as steel, followed by additional heat treatments to further enhance strength.
Typical hot forging temperatures are as follows: Aluminum (Al) Alloys - 360°C (680°F) to 520°C (968°F); Copper (Cu) Alloys - 700°C (1,292°F) to 800°C (1,472°F); Steel - up to 1,150°C (2,102°F).
In the hot forging process, metals are heated beyond their recrystallization points, ensuring they don't strain harden during deformation. This involves heating metals and forming them within molds that can be similarly heated, allowing for the crafting of intricate designs that cold forging cannot achieve.
For difficult-to-work alloys like superalloys, isothermal forging is employed to minimize oxidation, maintaining optimal temperatures throughout. This unique hot forging method keeps the workpiece at peak temperature, facilitating precise and consistent shaping.
To maintain the necessary temperature, molds are heated to either match or slightly trail the workpiece's temperature. This technique prevents premature cooling at contact points, enhancing the metal's flow characteristics for superior results.
