Conveniently situated 200km from Beijing, our factory boasts over 30 illustrious years of excellence in the custom forging industry. As a pioneer in traditional forging methods, we pride ourselves on not just adopting industry best practices, but also on our proactive approach to integrating cutting-edge techniques and advanced machinery. Our dedication to innovation and improvement is unwavering as we strive tirelessly to meet and exceed the ever-evolving demands of the market.
Forging, a time-honored technique in the realm of metalworking, stands the test of time as one of the most efficient methods available today. At its essence, forging involves shaping solid metal, never allowing it to reach a molten state. The art lies in meticulously manipulating the metal through techniques like hammering, rolling, or pressing. While numerous forging methodologies exist, each boasting unique benefits, most share a common thread: heating the workpiece to high temperatures to facilitate exquisite shaping endeavors.
When compared to casting or alternative metalworking strategies, forging emerges as the method of choice, offering unparalleled physical attributes such as superior tensile strength at a cost-effective price. This coveted strength is derived from the transformation of the metal's grain structure. Since the metal remains solid throughout, the applied forces during forging coerce the grain to adhere to the flow of the final design, resulting in components with robustness that outshines machined and casted alternatives.
CMC Forge opens the door to these distinguished benefits, serving a diverse clientele with a comprehensive suite of expert forging services tailored to meet the multifaceted demands of various industries and applications.
THE FORGING PROCESS
Within the vast landscape of forging, numerous subtypes exist, each bringing its own nuances to the creation of a product. Despite these variations, most forging follows a universal procedural framework.
Delve into the world of metal forming with the two dominant processes - hot forging and cold forging. Though both techniques strive for similar end results, their approaches differ significantly.
Hot forging stands out by requiring the metal to be heated above its recrystallization temperature, sometimes reaching a blazing 2,300 degrees Fahrenheit. The primary allure of hot forging lies in its reduced energy demands to shape metals effectively. This is attributed to the intense heat, which lowers yield strength while enhancing ductility. Additionally, hot forged products enjoy improved consistency, free from chemical anomalies.
Cold forging, on the other hand, is often executed at room temperature, though any situation below recrystallization is feasible. Some metals, like high-carbon steel, present challenges due to their formidable strength when cold forged. Nevertheless, cold forging offers superior advantages in terms of dimensional precision, consistent product quality, impeccable surface finishes, and minimal contamination. Encompassing a myriad of techniques like bending, extruding, cold drawing, and cold heading, cold forging's versatility is unrivaled. However, the trade-off is the necessity for more powerful machinery and potential intermediate anneals.
ADVANTAGES: Unlocking the Potential of Forging
Introducing our unparalleled range of superior-quality hot forging parts and components, tailored for diverse industries such as automotive, food dairy, machinery, medical, plumbing, watering, mining, petrochemical, electrical, energy, aerospace, submarine, and more.
Hot forging stands out by crafting some of the most robust manufactured parts and components, surpassing other metal manufacturing methods. Our expertise spans from creating lightweight components weighing mere grams to formidable parts exceeding hundreds of kilograms. For those requiring specialized surface finishes, we offer an extensive array of secondary operations including precision machining and advanced surface finishing.
Hot forging is a transformative process where metal is heated above its recrystallization temperature, reducing flow stress and required energy, thus enhancing production efficiency. This method not only facilitates easier shaping of metal but also minimizes the risk of fracturing.
Iron and its resilient alloys are predominantly subjected to hot forging due to two pivotal reasons: #1) As work hardening advances, hard metals like steel and iron become more challenging to manipulate. #2) Hot forging offers an economical approach, followed by heat treatments that further reinforce metals like steel through various strengthening processes beyond just cold working.
The average temperatures crucial for hot forging include: Aluminum (Al) Alloys ranging between 360°C (680°F) to 520°C (968°F); Copper (Cu) Alloys from 700°C (1,292°F) to 800°C (1,472°F); and Steel reaching up to 1,150°C (2,102°F).
In the art of hot forging, metal is heated beyond its recrystallization threshold, averting strain hardening during deformation. This sophisticated process involves elevating the metal's temperature, followed by molding it within heated dies. The metal's malleability at these high temperatures permits the creation of intricate shapes not feasible through cold forging.
For superalloys with limited malleability, isothermal forging-deformation in a controlled atmosphere-is employed to prevent oxidation. Isothermal forging, synonymous with hot forging, sustains the workpiece at its peak temperature throughout formation, ensuring optimal material properties.
Achieving this thermal consistency is realized by heating the mold to match or slightly trail the workpiece temperature. Such synchronization in temperature not only molds the workpiece effectively but also prevents premature cooling, thereby enhancing the metal's flow characteristics.
