Botou Casting Machinery Factory, the esteemed predecessor of Cangzhou Metallic Crafts Co., Ltd, proudly resides in the heart of Botou, a renowned hub for casting and forging in Hebei province, China. Strategically located just 200 km from Beijing, our factory boasts an impressive legacy of over 30 years in the custom forging industry. As a stalwart in traditional forging, we embrace the wisdom of experience while passionately pioneering cutting-edge techniques and machinery. Our unwavering commitment to innovation and quality propels us to continuously evolve and excel in meeting the ever-changing demands of the market. We are dedicated to crafting excellence and delight in every forged component.
Forging, a timeless artistry of metalworking, has stood the test of time as one of the most effective methods in the industry. At its essence, forging involves the meticulous shaping of raw metal, retaining its solid state and never succumbing to melting. This powerful technique includes a symphony of methods such as hammering, rolling, and pressing, each uniquely designed to mold metal with precision. With numerous variations available, each offering unique benefits, forging typically involves elevating the workpiece to soaring temperatures to ease the transformation process.
In the realm of metalworking, forging triumphs over casting and other techniques by delivering unparalleled physical characteristics, notably a superior tensile strength, all at an enticing cost. These exceptional attributes arise from altering the metal's grain structure. As the metal remains solid and un-melted, the forceful impact and compression during forging guide the grain along the contours of the final creation. This process crafts components of extraordinary strength, outshining their machined and casted counterparts.
At CMC Forge, we are devoted to bringing these remarkable advantages to clients across diverse sectors. Our extensive array of specialized forging services is meticulously crafted to fulfill the needs of an extensive range of applications.
THE FORGING PROCESS
The forging process encompasses a myriad of subtypes, leading to variations in the steps taken to form a product. Despite the diversity, most techniques adhere to a general framework.
In the realm of metal forming, two paramount techniques reign supreme: hot forging and cold forging. While both processes sculpt metals into desired forms, they achieve these results through distinct paths.
Hot forging involves elevating metals to an impressive temperature above their recrystallization point, often soaring to 2,300 degrees Fahrenheit. The key advantage here is the significant reduction in the energy required to shape the metal. This is attributed to the fact that extreme heat reduces yield strength while enhancing ductility. Furthermore, hot forged products gain from the eradication of chemical inconsistencies, offering a pristine and robust finish.
Cold forging, in contrast, generally operates at ambient temperatures, though it can extend to any temperature beneath recrystallization. Certain metals, particularly those like high-carbon steel, pose challenges due to their inherent strength, making cold forging more demanding. Nonetheless, cold forging triumphs in delivering precise dimensional accuracy, uniformity, superior surface finishes, and minimal contamination. It encompasses a variety of techniques such as bending, extruding, cold drawing, and cold heading. However, these benefits do come with increased equipment demands and the potential necessity for intermediate anneals.
ADVANTAGES
Experience exceptional quality with our hot forging parts and components, catering to a broad spectrum of sectors including automotive, food dairy, machinery, medical, plumbing, watering, mining, petrochemical, electrical, energy, aerospace, submarine, and beyond.
Hot forging is celebrated for producing some of the most resilient and durable parts and components, surpassing other metal manufacturing methods. We specialize in crafting hot forging parts and components that range from mere grams to several hundred kilograms. For those with unique surface finish needs, we extend an extensive array of secondary operations such as machining and surface finishing.
Hot forging involves heating metal beyond its recrystallization temperature, which effectively reduces the stress and energy required for metal shaping, thereby accelerating production rates. This technique facilitates easier metal shaping and minimizes the risk of fractures.
Hot forging is predominantly used for iron and its alloys due to two primary factors: #1) Progression of work hardening makes materials like steel and iron increasingly challenging to handle, #2) It offers a cost-effective method to forge metals such as steel, followed by heat treatment to enhance strength, as not all strengthening processes rely solely on cold working methods.
Typical hot forging temperature ranges include: Aluminum (Al) Alloys from 360°C (680°F) to 520°C (968°F); Copper (Cu) Alloys ranging from 700°C (1,292°F) to 800°C (1,472°F); Steel up to 1,150°C (2,102°F).
In hot forging, temperatures exceed the metal's recrystallization point, preventing strain hardening during deformation. This process involves heating the metal above its recrystallization temperature and shaping it in a mold, which can also be heated. The high temperature allows for enhanced malleability, enabling more intricate shapes compared to cold forging.
For low-malleability superalloys, isothermal or hot forging processes are employed within controlled atmospheres to prevent oxidation. Isothermal forging maintains the workpiece at peak temperatures throughout forming, ensuring optimal results.
The mold heating maintains its temperature just below or at the workpiece level, ensuring consistent temperature during formation. This eliminates cooling at the mold interfaces, thereby enhancing the metal's flow properties.
