Botou Casting Machinery Factory, the esteemed predecessor of Cangzhou Metallic Crafts Co., Ltd, is strategically situated in the renowned casting and forging hub of Botou, nestled within Hebei province, China. Just 200 kilometers from the bustling capital city of Beijing, our factory boasts an impressive legacy of over 30 years in the custom forging industry. As a stalwart in traditional forging, we not only draw inspiration from established expertise but also ardently embrace cutting-edge techniques and state-of-the-art machinery. Our commitment to innovation and excellence drives our continuous development and enhancement, ensuring that we consistently meet and exceed the ever-evolving demands of the market.
Although forging is one of the most ancient methodologies of metalworking, it continues to stand the test of time as one of the most efficacious techniques available. At its essence, forging involves manipulating raw metal in its solid state without permitting it to fully liquefy. The process unfolds as an artisan operator skillfully employs a medley of techniques-be it hammering, rolling, or pressing-to shape the metal. While the realm of forging is diverse, with each variant offering unique advantages, the common thread is the heating of workpieces to extreme temperatures to aid in these innovative shaping endeavors.
When pitted against casting or alternative metalworking methods, forging emerges as the champion, delivering optimal physical traits-most notably, unparalleled tensile strength-while maintaining an appealing cost-effectiveness. These advantageous properties primarily stem from the metallurgical transformation within the grain structure. As the material never reaches a molten state, the vigorous percussive or compressive forces in forging compel the grain to align with the flow of the finished masterpiece, resulting in components that are significantly sturdier than their machined or casted equivalents.
CMC Forge brings these extraordinary benefits to a diverse clientele spanning various industries, proudly offering a comprehensive suite of expert forging services tailored to meet the multifaceted demands of a wide array of applications.
THE ART AND SCIENCE OF THE FORGING PROCESS
The world of forging encompasses a multitude of subtypes, meaning the steps in crafting a product can differ. Yet, most share a foundational blueprint.
Forging is a fascinating world of metal manipulation, where two primary processes - hot forging and cold forging - dominate the scene. These two methods, while delivering comparable outcomes, offer distinct approaches to shaping metals.
Hot forging is a process that involves heating metals beyond their recrystallization temperatures, often reaching up to an intense 2,300 degrees Fahrenheit. The allure of hot forging lies in its reduced energy demands for shaping metals. This is due to the lowered yield strength and enhanced ductility achieved through high temperatures. Furthermore, hot forged items enjoy the benefit of removed chemical inconsistencies, resulting in a more uniform and reliable end product.
Cold forging, in contrast, operates at room temperature or any temperature below recrystallization. While certain robust metals, like high-carbon steel, pose challenges for cold forging, this technique shines in its superior dimensional precision, uniformity, and surface quality. Cold forging embraces a variety of methods such as bending, extruding, cold drawing, and cold heading, offering flexibility with a few trade-offs. However, it demands stronger machinery and sometimes intermediate annealing, adding complexity to its versatility.
ADVANTAGES
Our company specializes in delivering exceptional quality hot forging parts and components, catering to an impressive array of industries such as automotive, food and dairy, machinery, medical, plumbing, watering, mining, petrochemical, electrical, energy, aerospace, submarine, and many others.
Renowned for producing some of the most robust manufactured parts, hot forging stands out among metal manufacturing processes. We craft hot forging parts and components ranging from a few grams to several hundred kilograms. For those with unique surface finish demands, we offer an extensive suite of secondary operations, including precision machining and surface finishing.
Hot forging is a sophisticated process where metal is heated beyond its recrystallization temperature. This reduces the flow stress and the energy needed for shaping the metal, significantly boosting production rates. It facilitates easier shaping of metals and minimizes the risk of fracture, ensuring higher efficiency and quality.
Iron and its alloys are predominantly hot forged, mainly because: #1) Work hardening can make tough materials like steel and iron increasingly difficult to handle, and #2) Hot forging metals like steel is more cost-effective, followed by heat treatment processes, enhancing their strength beyond just cold working.
Typical hot forging temperatures include: 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 - reaching up to 1,150°C (2,102°F).
In hot forging, metals are heated above their recrystallization point to avoid strain hardening during deformation. This involves heating the metal above this point and forging it into a mold that may also be heated. The high temperature allows easy shaping, enabling the creation of intricate designs unachievable through cold forging.
For low malleability superalloys, isothermal forging-a process conducted in a controlled atmosphere-is utilized to prevent oxidation. Also known as hot forging, this technique maintains the workpiece at its peak temperature throughout forming, ensuring optimal results.
This temperature maintenance is achieved by heating the mold to an elevated or slightly lower temperature than the workpiece, preventing cooling at the contact surfaces. This enhances the metal's flow properties, leading to superior forging quality and performance.
