Botou Casting Machinery Factory, the esteemed precursor to Cangzhou Metallic Crafts Co., Ltd, is proudly positioned in the heart of the casting and forging hub of Botou, nestled in the vibrant Hebei province of China. Perfectly situated, it lies just 200 kilometers from the bustling capital, Beijing. For over three decades, our factory has been steadfast in the custom forging industry, upholding time-honored traditions while embracing innovation and modernity. As a distinguished forging manufacturer, we thrive on assimilating valuable experiences from others and prioritizing the integration of cutting-edge techniques and state-of-the-art machinery. We are committed to continuous development and refinement, passionately striving to align our offerings with the dynamic demands of the market.
Even though forging is among the ancient arts of metalworking, its relevance and efficacy are timeless. At its essence, forging elegantly transforms raw metal without succumbing the material to a molten state. The metal remains steadfast in a solid form, enabling skilled artisans to employ a symphony of forming techniques such as hammering, rolling, or pressing. Despite the many distinct variations of forging-each with its unique set of advantages-most methodologies involve elevating the workpiece to soaring temperatures to seamlessly facilitate these ingenious shaping processes.
When placed beside casting or alternative metalworking techniques, forging stands tall, delivering the ultimate physical attributes-most notably, an unparalleled level of tensile strength-while being mindful of cost efficiency. These extraordinary qualities arise primarily from the meticulous refinement of the metal's grain. Since the material never reaches a molten state, the percussive or compressive forces employed during forging meticulously guide the grain to embrace the flow of the final creation. The result? Components imbued with strength far surpassing that of their machined and casted peers.
CMC Forge transcends industry boundaries by providing these remarkable advantages to clients far and wide, offering a comprehensive suite of expert forging services tailored to a diverse spectrum of applications.
THE FORGING PROCESS: Crafting Excellence from Metal
The forging process is a tapestry of subtypes, with each variant weaving its own unique set of steps. However, the majority of procedures adhere to a foundational blueprint, ensuring consistency and precision in forming the desired product.
Discover the art of metalcraft with two paramount techniques: hot forging and cold forging. Both are unique metal forming processes that, while distinct in their approach, pave the way to achieve exceptional results in metalworking.
Hot forging emerges as a process where metals are heated beyond their recrystallization temperature, sometimes soaring to a blazing 2,300 degrees Fahrenheit. This intense heat dramatically reduces the energy needed for shaping, unlocking ease in forming due to lowered yield strength and enhanced ductility. Furthermore, hot forging eradicates chemical inconsistencies, paving the path for superior-quality finished products.
Cold forging, on the other hand, is often executed at room temperature, though any temperature beneath recrystallization serves the purpose. Strengthened metals, such as high-carbon steel, challenge this process due to their robust nature. Yet, the advantage lies in cold forging's precision: it excels in dimensional accuracy, product consistency, refined surface finish, and minimal contamination. This diverse method includes bending, extruding, cold drawing, and cold heading. With its multitude of techniques, cold forging does demand more potent machinery and may necessitate intermediate anneals, balancing versatility with complexity.
ADVANTAGES
We provide an unparalleled selection of high-quality hot forging parts and components across an extensive array of industries. From automotive and food dairy to machinery, medical, plumbing, and watering, our services extend to mining, petrochemical, electrical, energy, aerospace, submarine, and beyond.
Renowned for creating some of the most robust manufactured parts, our hot forging process stands out amidst other metal manufacturing techniques. We expertly craft hot forging parts and components ranging from a few grams to over several hundred kilograms. For specialized surface finish requirements, we offer an expansive suite of secondary operations including precise machining and refined surface finishing.
Hot forging involves heating metal beyond its recrystallization temperature, significantly lowering the flow stress and energy required for shaping. This method not only enhances production efficiency but also facilitates shaping while reducing the risk of fracture.
Iron, along with its alloys, is predominantly hot forged, primarily for two reasons: #1) Work hardening makes hard materials like steel and iron increasingly difficult to manipulate. #2) This economical approach allows subsequent heat treatments to enhance the strength of metals like steel, beyond what cold working alone can achieve.
Typical temperatures for hot forging include: Aluminum Alloys - 360° (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 hot forging, metals are heated above their recrystallization point, allowing for plastic deformation without strain hardening. The process involves molding the heated metal into desired shapes, where high temperatures facilitate the creation of intricate designs that are challenging to achieve with cold forging.
For superalloys with low malleability, isothermal forging is employed in a controlled atmosphere to prevent oxidation. This hot forging variant maintains the workpiece at peak temperature throughout, ensuring optimal shaping without compromising structural integrity.
To maintain high temperatures, molds are heated to match or slightly differ from the workpiece temperature. This eliminates cooling between mold interfaces, enhancing the metal's flow properties, and ensuring superior workmanship.
