To enhance the core technological competitiveness of the company and develop its own core production processes, our factory is actively introducing automated forging equipment. Currently, our factory has implemented automated production equipment in multiple stages of the forging process, simplifying the need for operator intervention. This enables automatic recording, analysis, and processing of production information, achieving advanced, efficient, and flexible production.
Botou Casting Machinery Factory, former of Cangzhou Metallic Crafts Co., Ltd, is located in the casting & forging industrial town of Botou in Hebei province of China, 200km far away from Beijing. Factory is overy 30 years in the custom forging industry. As a traditional forging manufacturer, we are not only learn other experience, but also pay more attention to bring in the new technique and machine. We are pleasent to develop & improve us to satisfy with the market's demand.
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.
There are two main types of forging - hot forging and cold forging. Hot forging and cold forging are two different metal forming processes that deliver similar results.
Hot forging requires the metal to be heated above its recrystallization temperature. This can mean heating metals up to 2,300 degrees Fahrenheit. The main benefit of hot forging is the decrease in energy required to form the metal properly. This is because excessive heat decreases yield strength and improves ductility. Hot forged products also benefit from the elimination of chemical inconsistencies.
Cold forging typically refers to forging a metal at room temperature, though any temperature below recrystallization is possible. Many metals, such as steel high in carbon, are simply too strong for cold forging. Despite this hindrance, cold forging does edge out its warmer equivalent when it comes to standards of dimensional control, product uniformity, surface finish and contamination. Cold forging encompasses numerous techniques, including bending, extruding, cold drawing and cold heading. However, this increased versatility comes at a cost, because cold forging requires more powerful equipment and may call for the use of intermediate anneals.
ADVANTAGES
provides superior quality hot forging parts and components for a wide range of industries including automotive, food dairy, machinery, medical, plumbing, watering, mining, petrochemical, electrical, energy, aerospace, submarine and others.
Hot forging is known to produce some of the strongest manufactured parts and components compared to other metal manufacturing processes. We produce hot forging parts and components from a few grams to more than a few hundred kilograms. For hot forging parts with special surface finish requirements, we provide a broad range of secondary operation including machining, surface finishing, etc.
Hot forging requires the metal to be heated above its recrystallization temperature. This allows for the flow stress and energy required to form the metal to lower, effectively increasing the rate of production (or strain rate). Hot forging aids in making the metal easier to shape as well as less likely to fracture.
Iron, along with its alloys, are almost always hot forged for two main reasons: #1) If work hardening progresses, hard materials (such as steel and iron) will become more difficult to work with, and #2) It is a more economical option to hot forge metals such as steel and then follow with heat treatment processes as metals such as steel can be strengthened through other processes (and not necessarily just cold working processes).
Average temperatures for hot forging includes: Aluminum (Al) Alloys - 360° (680°F) to 520°C (968°F); Copper (Cu) Alloys - 700°C (1 292°F) - 800°C (1 472°F); Steel - up to 1 150°C (2 102°F)
During hot forging, the temperature reaches above the recrystallization point of the formed metal. As the step of plastically deforming the metal above the recrystallization temperature, these high temperatures are required in order to avoid strain hardening during deformation. This process typically involves heating the metal (above its recrystallization point) and then comminuting it into a mold that can also be heated as needed. Because the metal is hot, it is easy to "move" and enables manufacturers to make more complex shapes than cold forging.
For superalloys, which have low malleability, processes such as isothermal forging (deformation in a controlled atmosphere) are used to avoid oxidation. Isothermal forging, also known as hot forging, is a thermal processing process that keeps a workpiece at its maximum temperature throughout the forming process.
Maintaining this temperature is done by heating the mold - it will be at an elevated or slightly lower temperature of the workpiece. The force applied by the mold forms the workpiece, and because the mold is also at an elevated temperature, the cooling of the workpiece between the mold working interfaces is eliminated. This in turn leads to an improvement in the flow properties of the metal (work piece).
