Botou Casting Machinery Factory, the proud precursor of Cangzhou Metallic Crafts Co., Ltd, is nestled in the renowned casting & forging industrial hub of Botou, Hebei province, China, strategically positioned just 200km from Beijing. With an illustrious legacy spanning over 30 years in the bespoke forging sector, our factory stands as a beacon of craftsmanship and innovation. As a venerable name in traditional forging, we not only assimilate the best practices from our peers but are passionately dedicated to integrating cutting-edge techniques and state-of-the-art machinery. Our relentless commitment to development and enhancement ensures that we consistently meet and exceed the evolving demands of the market.
Forging, an age-old yet incredibly effective method of metalworking, remains as impactful today as ever. This time-honored process involves strategically forming raw metal while it remains solid, without ever allowing it to melt completely. Skilled operators employ various dynamic techniques, including hammering, rolling, and pressing, to skillfully sculpt the metal into exceptional forms. While several forging variations exist-each offering unique benefits-most processes involve heating the workpiece to soaring temperatures, primed for precise and intricate shaping.
In comparison to casting and other metalworking techniques, forging stands unrivaled in delivering exceptional physical qualities, notably an extraordinary level of tensile strength-all at a compelling value. Such superior attributes stem from the intentional alteration of the metal's grain. As the material is never melted during forging, the powerful forces exerted, whether percussive or compressive, direct the grain to align seamlessly with the flow of the finished masterpiece. This results in components of unparalleled strength, far surpassing their machined and casted counterparts.
CMC Forge brings these remarkable forging advantages to a vast array of industries, offering a comprehensive suite of expert forging services tailored to meet a diverse range of application needs.
UNDERSTANDING THE INTRICACIES OF THE FORGING PROCESS
The realm of forging is vast, with numerous subtypes that can alter the specific steps involved in crafting a product. Nevertheless, most procedures adhere to a consistent general framework.
Exploring the realm of forging, we find two predominant methods - hot forging and cold forging. Both of these metal forming processes skillfully craft similar end results, yet they achieve them through distinctly different paths.
Hot forging is an awe-inspiring process that involves elevating the metal's temperature beyond its recrystallization point, often requiring it to be heated up to an astonishing 2,300 degrees Fahrenheit. This intense heat significantly reduces the energy needed to expertly shape the metal, as it lowers yield strength while enhancing ductility. Moreover, hot forging gifts the finished products with the advantage of eradicating chemical inconsistencies, ensuring a flawless result.
In contrast, cold forging is a process that typically operates at room temperature, though it can occur at any temperature below recrystallization. Certain robust metals, like high-carbon steel, defy cold forging due to their sheer strength. Nevertheless, cold forging triumphs over its heated counterpart in achieving superior standards of dimensional precision, product uniformity, exceptional surface finish, and minimized contamination. This versatile method employs a variety of techniques such as bending, extruding, cold drawing, and cold heading, but requires more formidable equipment and sometimes intermediate anneals, reflecting its complexity.
ADVANTAGES
Experience the excellence of superior quality hot forged parts and components, crafted for a diverse spectrum of industries, including automotive, food and dairy, machinery, medical, plumbing, watering, mining, petrochemical, electrical, energy, aerospace, submarine, and more.
Hot forging stands out as a premier method for producing exceptionally strong manufactured parts and components, surpassing other metal manufacturing methods. Our expertise spans the production of hot forged parts ranging from a few grams to several hundred kilograms. For parts requiring special surface finishes, we offer an extensive array of secondary processes such as precision machining and advanced surface finishing.
Hot forging involves heating metal beyond its recrystallization temperature, significantly reducing flow stress and energy requirements. This process enhances production rates and makes the metal more pliable, reducing the risk of fractures during shaping.
Iron and its alloys are prime candidates for hot forging due to two pivotal reasons: #1) Preventing work hardening, which makes hard materials like steel and iron challenging to mold, and #2) Optimizing cost-effectiveness, as hot forging steel followed by heat treatment can strengthen the metal without solely relying on cold working methods.
Typical temperatures for hot forging include: Aluminum (Al) Alloys at 360° (680°F) to 520°C (968°F); Copper (Cu) Alloys at 700°C (1,292°F) to 800°C (1,472°F); Steel up to 1,150°C (2,102°F).
Hot forging involves elevating the metal's temperature above its recrystallization point before deformation. This high-temperature process prevents strain hardening while allowing the metal to be easily shaped into complex forms. The procedure encompasses heating the metal and using a mold, also heated, to achieve the desired shape, thereby enhancing the complexity achievable in hot forging compared to cold methods.
For materials like superalloys, known for low malleability, specialized processes such as isothermal forging are employed to prevent oxidation. This method, synonymous with hot forging, involves maintaining the workpiece at peak temperature throughout the forming process in a controlled atmosphere.
Achieving consistent temperatures is managed by heating the mold to an elevated or slightly lower level than the workpiece. This ensures seamless force application, eliminating cooling at mold interfaces, and significantly enhancing the metal's flow properties.
