Botou Casting Machinery Factory, once known as Cangzhou Metallic Crafts Co., Ltd, proudly stands in the heart of China's renowned casting & forging hub, Botou, in Hebei province. Our strategic location is just 200km from Beijing. With a legacy spanning over 30 years in the custom forging industry, we have honed our craft to perfection. As a venerable yet forward-thinking forging manufacturer, we embrace the richness of traditional expertise while continuously integrating cutting-edge techniques and machinery. Our commitment to innovation ensures that we evolve to meet the dynamic demands of the market, and we take great pleasure in growing and enhancing our capabilities to exceed customer expectations.
Forging, an age-old art in metalworking, continues to impress with its unrivaled efficacy and precision. This time-honored technique masterfully crafts metals into desired shapes without fully melting the material, maintaining its solid state. Skilled operators employ a myriad of techniques-hammering, rolling, or pressing-each tailored to perfection. While the forging spectrum boasts numerous variations, each with unique advantages, most processes share a common thread: heating the workpiece to elevated temperatures to seamlessly mold it.
Forging stands out among metalworking techniques for delivering unparalleled physical qualities, notably exceptional tensile strength, coupled with cost-effectiveness. The key to these properties lies in the transformation of the metal's grain structure. Unlike casting, where materials melt, forging's compressive forces guide the grain to follow the contours of the final product, culminating in components of superior strength compared to their machined or cast counterparts.
CMC Forge extends these forging benefits to diverse industries, delivering a comprehensive suite of expert forging services tailored to a wide spectrum of applications.
THE FORGING PROCESS
Within the expansive realm of forging, diverse subtypes dictate the exact steps for forming a product, yet generally adhere to a similar foundational process.
Discover the fascinating world of metal forging, which is dominated by two principal techniques: hot forging and cold forging. Although both processes sculpt metal to achieve remarkable results, they employ distinct methodologies to attain their impressive outcomes.
Hot forging is a dynamic process where metals are heated to temperatures above their recrystallization thresholds, reaching as high as 2,300 degrees Fahrenheit. This intense heat treatment significantly lowers the energy needed for shaping, as it reduces yield strength and enhances ductility. The result is not only a more easily formed metal, but also products free from chemical inconsistencies, a hallmark of quality and reliability in hot forged items.
Cold forging, on the other hand, works its transformative magic at or near room temperature, maintaining the metal's structural integrity through a process that can involve any temperature below its recrystallization point. While some metals, especially high-carbon steel, resist cold forging due to their inherent strength, the technique shines in its superior dimensional accuracy, uniformity, surface finish, and reduced risk of contamination. This process includes versatile methods like bending, extruding, cold drawing, and cold heading. However, such precision and versatility require robust equipment and often demand intermediate annealing, adding to the complexity and cost.
ADVANTAGES

We cater to automotive, food & dairy, machinery, medical, plumbing, watering, mining, petrochemical, electrical, energy, aerospace, submarine, and a plethora of other sectors.
Renowned for its ability to yield extraordinarily strong parts, hot forging surpasses other metal manufacturing processes. Our capabilities range from producing parts as light as a few grams to those weighing several hundred kilograms. For components requiring special surface finishes, we offer a comprehensive suite of secondary operations, including precision machining and various surface finishing techniques.
Hot forging is a process that involves heating metal above its recrystallization temperature. This crucial step reduces the flow stress and energy needed to shape the metal, vastly elevating production rates. The process not only makes the metal easier to mold but also diminishes the risk of fracture.
Metals like iron and its alloys are predominantly hot forged for two compelling reasons: #1) As work hardening progresses, these robust materials, including steel and iron, become increasingly challenging to manipulate. #2) Economically, it is more advantageous to hot forge and then apply heat treatment processes, as it allows metals like steel to be fortified through various methods, beyond just cold working.
Typical hot forging temperatures for different metals include: Aluminum (Al) Alloys - 360°C (680°F) to 520°C (968°F), Copper (Cu) Alloys - 700°C (1,292°F) - 800°C (1,472°F), and Steel - up to 1,150°C (2,102°F).
In hot forging, temperatures soar beyond the metal's recrystallization point to prevent strain hardening during deformation. This involves heating the metal above its recrystallization temperature and then molding it into a shaped form. The heated metal's malleability facilitates the crafting of more intricate shapes compared to cold forging.
For superalloys marked by low malleability, advanced processes such as isothermal forging-deformation within a controlled environment-are employed to combat oxidation. This technique, synonymous with hot forging, maintains the workpiece at peak temperature throughout the forming process.
Temperature maintenance is achieved by heating the mold to an elevated or slightly lower temperature than the workpiece. This ensures that cooling of the workpiece at the mold interface is minimized, enhancing the metal's flow properties and achieving superior formation.
