Botou Casting Machinery Factory, the esteemed predecessor of Cangzhou Metallic Crafts Co., Ltd, proudly resides in the renowned casting and forging industrial hub of Botou, nestled in the heart of Hebei province, China, just a convenient 200km journey from the vibrant city of Beijing. With an impressive legacy spanning over three decades in the custom forging industry, we stand as a beacon of tradition and innovation. As a distinguished forging manufacturer, we not only embrace the wisdom and insights gleaned from industry pioneers but also dedicate ourselves to the continuous adoption of cutting-edge techniques and state-of-the-art machinery. We are passionately committed to evolving and enhancing our capabilities to meet and exceed the ever-changing demands of the market.
Forging, a time-honored craft in the realm of metalworking, stands as a testament to its enduring efficacy. At the heart of this process lies the art of shaping raw metal without succumbing to the melting point, allowing the metal to retain solidity as skilled operators employ a symphony of techniques such as hammering, rolling, or pressing. This ancient craft presents countless variations, each with its unique advantages, yet most prominently involve the high-temperature heating of the workpiece to ease the transformation.
When stacked against casting or other metalworking techniques, forging emerges as the champion, delivering unparalleled physical prowess - notably a remarkable tensile strength - at a compelling cost. These favorable traits are rooted in the transformation of the metal's grain, a process where, without melting, the forces of compression guide the grain to flow seamlessly with the contours of the final product. This results in components that boast superior strength compared to their machined and casted peers.
CMC Forge extends these forging benefits across diverse industries, offering a comprehensive suite of expert forging services designed to cater to a vast array of applications.
THE FORGING PROCESS
The expansive world of forging encompasses numerous subtypes, making the exact pathway to crafting a product peppered with potential variations. Nevertheless, most forging endeavors adhere to a foundational roadmap.
There are two principal methods in the world of metal forging: hot forging and cold forging. These distinct processes shape metals in unique ways, yet they both yield impressively similar outcomes.
Hot forging is a sophisticated process that involves heating metals beyond their recrystallization temperature, sometimes up to a searing 2,300 degrees Fahrenheit. The primary advantage of hot forging lies in the significant reduction of energy needed to mold the metal. This is because the intense heat diminishes yield strength while enhancing ductility, resulting in products that also enjoy the eradication of chemical inconsistencies.
Cold forging, on the other hand, involves shaping metal at ambient temperatures - or any temperature below its recrystallization point. While robust metals like high-carbon steel pose a challenge for cold forging, this process still leads in terms of achieving superior dimensional accuracy, uniformity, and surface quality. Cold forging boasts a wide array of techniques including bending, extruding, cold drawing, and cold heading. However, these capabilities can increase costs due to the need for more robust equipment and the potential necessity of intermediate annealing.
ADVANTAGES

Our expertise caters to fields such as automotive, food dairy, machinery, medical, plumbing, watering, mining, petrochemical, electrical, energy, aerospace, submarine, and beyond.
Renowned for its ability to produce some of the strongest manufactured parts and components, hot forging is a leading metal manufacturing process. We excel in creating hot forging parts ranging from a few grams to an impressive few hundred kilograms. For those parts requiring a special surface finish, we offer an extensive array of secondary operations, including precision machining and expert surface finishing.
Hot forging involves heating the metal beyond its recrystallization temperature, significantly reducing the flow stress and energy needed for forming. This process enhances production rates by making metals easier to shape and less prone to fracturing, ensuring superior quality and efficiency.
Iron and its alloys are predominantly hot forged due to two compelling reasons: #1) As work hardening advances, materials like steel and iron become increasingly challenging to manipulate. #2) Hot forging presents an economical method, allowing further strengthening through heat treatment processes, rather than solely relying on cold working techniques.
Hot forging temperatures typically include: Aluminum (Al) Alloys from 360° (680°F) to 520°C (968°F); Copper (Cu) Alloys range from 700°C (1 292°F) to 800°C (1 472°F); and Steel can reach up to 1 150°C (2 102°F).
The art of hot forging demands heating metals above their recrystallization point, enabling seamless deformation without the risk of strain hardening. This high-temperature technique involves heating the metal and comminuting it into a mold that can be equally heated as required, allowing for the creation of intricate and complex shapes effortlessly.
For materials like superalloys with low malleability, isothermal forging-performed in a controlled atmosphere-prevents oxidation and ensures optimal results. Isothermal forging, akin to hot forging, maintains the workpiece at peak temperature throughout forming, ensuring precision and quality.
By maintaining the mold at an elevated or slightly lower temperature than the workpiece, we eliminate cooling at the mold interfaces, enhancing the flow properties of the metal and producing superior quality components.
