Nestled in the heart of Botou, the renowned casting and forging industrial town of Hebei Province, China, Botou Casting Machinery Factory, the predecessor of the esteemed Cangzhou Metallic Crafts Co., Ltd, has a rich heritage spanning over three decades in the custom forging industry. Just 200 kilometers from the bustling metropolis of Beijing, our factory is a beacon of tradition and innovation. As a stalwart in the traditional forging sector, we not only draw inspiration from the best practices of our peers but are relentless in our pursuit of pioneering new techniques and machinery. Our commitment to development and improvement is unwavering, ensuring we meet and exceed the ever-evolving demands of the market with utmost satisfaction.
Although forging is one of the oldest methods of metalworking, it remains one of the most effective to this day. At its core, forging is the process of forming raw metal without allowing the material to completely melt. The metal remains in a solid state while an operator performs any combination of forming techniques such as hammering, rolling, or pressing. While there are many variations of forging-each with their own distinct advantages-most involve heating the workpiece to very high temperatures to facilitate these shaping processes.
Compared to casting or other metalworking techniques, forging yields the most desirable physical characteristics-including a very high degree of tensile strength-at an attractive price-point. These beneficial properties primarily come from changes to the metal's grain. Since the material is never melted, the percussive or compressive forces applied during forging force the grain to follow the flow of the finished product. This creates components that are far stronger than their machined and casted counterparts.
CMC Forge makes these advantages accessible to clients across industries, offering a full range of skilled forging services that meet the needs of myriad applications.
THE FORGING PROCESS
There are many subtypes of the broader forging process, so the exact steps involved in forming a product may vary. Most procedures, however, will follow the same general outline.
In the world of metal forming, two primary methods stand apart: hot forging and cold forging. Both processes sculpt metal into desired forms, yet they employ distinct techniques to achieve their goals, delivering comparable end results.
Hot forging involves heating the metal beyond its recrystallization point, sometimes reaching soaring temperatures of up to 2,300 degrees Fahrenheit. This intense heat significantly reduces the energy needed to shape the metal effectively. The benefits of hot forging are manifold: it not only lowers the yield strength but also enhances ductility, providing superior malleability. Furthermore, products crafted through hot forging are often free from chemical inconsistencies, resulting in higher quality outcomes.
Cold forging, on the other hand, generally occurs at room temperature, though any temperature below the recrystallization point qualifies. While some robust metals, such as high-carbon steel, resist cold forging due to their strength, this method excels in precision. Cold forging is renowned for its superior dimensional control, uniformity, surface finish, and resistance to contamination. It includes a variety of techniques like bending, extruding, cold drawing, and cold heading. The versatility of cold forging, however, demands more powerful machinery and sometimes necessitates intermediate annealing, which can increase costs.

Hot forging involves heating metal beyond its recrystallization temperature, a crucial step that reduces the metal's flow stress and energy requirements for shaping. This elevated temperature facilitates easier shaping and significantly diminishes the risk of fractures, ultimately boosting production rates.
Iron and its alloys are predominantly hot forged due to two primary benefits: Firstly, the challenge of work hardening is mitigated, making it feasible to shape even hard materials like steel and iron. Secondly, hot forging is an economical choice, allowing steels to be subsequently strengthened through heat treatment rather than solely relying on cold working processes.
Typical hot forging temperatures are meticulously maintained: Aluminum (Al) Alloys - 360°C (680°F) to 520°C (968°F); Copper (Cu) Alloys - 700°C (1 292°F) to 800°C (1 472°F); Steel - reaching up to 1,150°C (2,102°F).
The hot forging process involves elevating the metal's temperature beyond its recrystallization point to prevent strain hardening. This involves heating the metal, and if necessary, the mold itself, allowing the metal to be plastically deformed into complex shapes with ease due to its heated state.
For superalloys with limited malleability, the technique of isothermal forging is employed. This method, synonymous with hot forging, occurs within a controlled atmosphere to avert oxidation. It maintains the workpiece at peak temperature throughout the forming process, ensuring optimal malleability and shape integrity.
Consistency in temperature is achieved by heating the mold, keeping it nearly as warm as the workpiece. This practice prevents premature cooling at the mold interfaces, enhancing the metal's flow properties and ensuring precision forming of complex shapes.
