Forging, an ancient yet remarkably enduring metalworking technique, remains unparalleled in its effectiveness even today. At its essence, forging is all about shaping raw metal without ever reaching its melting point. The metal is kept solid as skilled operators employ various techniques like hammering, rolling, or pressing. The world of forging offers an array of methods, each boasting unique advantages, yet most share a common thread: heating the metal workpiece to exceptionally high temperatures to ease its transformation into desired forms.
In comparison to casting or other metalworking methods, forging stands out for delivering superior physical qualities, such as exceptional tensile strength, all at an appealing cost. The secret behind these impressive attributes lies in the alteration of the metal's grain structure. Since the material is never liquefied, the impactful forces exerted during forging guide the grain to flow in harmony with the finished product's shape. This results in components that boast remarkable strength, far surpassing their machined and casted equivalents.
CMC Forge extends the myriad benefits of forging to clients across diverse industries, providing a comprehensive suite of expert forging services that cater to a wide range of applications and requirements.
UNVEILING THE FORGING PROCESS
The overarching forging process encompasses numerous specialized subtypes, each with its own unique steps to shape a product. Nonetheless, the majority of these procedures adhere to a broadly similar structure.
Forging processes are fundamental in metal forming, with two primary techniques: hot forging and cold forging. Both processes are designed to achieve similar structural transformations in metals, each offering unique benefits and operational methodologies.
Hot forging is characterized by heating metals beyond their recrystallization temperatures, often reaching up to an intense 2,300 degrees Fahrenheit. This process's key advantage is the reduced energy needed to mold the metal effectively, thanks to the significantly lowered yield strength and enhanced ductility achieved through high temperatures. Additionally, hot forging ensures the minimization of chemical inconsistencies, resulting in superior metallurgical quality.
Cold forging, on the other hand, is performed at or below room temperature, with the capability to work just below the metal's recrystallization point. While some metals, particularly high-carbon steels, are too robust for cold forging, this method triumphs in delivering precise dimensional accuracy, exceptional product uniformity, enhanced surface finishes, and minimal contamination. Despite its adaptability through methods like bending, extruding, cold drawing, and cold heading, cold forging demands more substantial equipment and often necessitates intermediate annealing, which can elevate production costs.
ADVANTAGES
Our company excels in delivering top-tier hot forging parts and components that cater to a diverse spectrum of industries. These include automotive, food and dairy, machinery, medical, plumbing, irrigation, mining, petrochemical, electrical, energy sectors, aerospace, submarine technology, and beyond.
Renowned for creating some of the most robust manufactured parts, hot forging surpasses many metal manufacturing processes. We are adept at crafting hot forging components, ranging from several grams to hundreds of kilograms. For those parts requiring exceptional surface finishes, we offer an extensive selection of secondary operations, including precision machining and refined surface finishing.
Hot forging involves heating the metal to a temperature above its recrystallization point, effectively lowering the flow stress and energy necessary for metal shaping, thus boosting production efficiency. This process facilitates easier metal shaping and reduces the risk of fractures.
Iron and its alloys are predominantly hot forged due to: #1) Avoiding complications from work hardening as materials such as steel and iron become tougher; and #2) Economical benefits, as hot forging followed by heat treatment can enhance steel's strength beyond what cold working alone can achieve.
The typical hot forging temperatures are: Aluminum Alloys - 360°C (680°F) to 520°C (968°F); Copper 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 temperature to facilitate plastic deformation and prevent strain hardening. This involves heating the metal and compressing it into a mold, which may also be heated. Due to the elevated temperature, the metal is more malleable, allowing manufacturers to create intricate shapes.
For superalloys with limited malleability, we utilize isothermal forging-conducted in a controlled environment to prevent oxidation. Known as hot forging, this method maintains the workpiece at peak temperature throughout the formation process.
To sustain the necessary temperature, molds are heated to levels matching or slightly lower than the workpiece. This ensures seamless shaping by maintaining the temperature at the mold's interface, thereby enhancing metal flow properties.
