Forging Casting Parts Processing Manufacturers

Forging and casting are both important metal processing methods in the industry, and they have wide-ranging applications. They have significant differences in terms of process principles, product characteristics, and application areas.

Forging is a metal processing method that uses forging machinery to apply pressure to metal blanks, causing them to undergo plastic deformation and obtain forged parts with specific mechanical properties, shapes, and sizes. During the forging process, the metal blank is subjected to pressure between the upper and lower anvil dies of the forging equipment, gradually achieving the desired shape and size through plastic deformation. This processing method can refine the grain structure and compact the material, thereby improving the mechanical and physical properties of the metal. Additionally, forged products have continuous fiber structures and reasonable flow lines, ensuring good mechanical properties and longer service life of the components.

Casting, on the other hand, involves pouring liquid metal into a casting cavity that matches the shape of the part. After cooling and solidification, the casting or casting blank is obtained. During the casting process, the molten metal fills the cavity under the influence of gravity and solidifies during the cooling process. This processing method can produce parts with complex shapes, with minimal restrictions and adaptability to a wide range of industrial metal materials. Furthermore, the shape and size of the casting are close to the final part, reducing the amount of machining required and enabling large-scale production.

Forging is mainly suitable for manufacturing high-strength, high-hardness, and high-precision parts, such as wind turbine main shafts, gear shafts for transmission equipment, and cylinder bodies. Forged products have a dense internal structure and higher physical properties, meeting the requirements of many high-strength and high-precision applications. Additionally, forging is also used to manufacture important structural components with low stress but high toughness requirements, such as shafts, rod system components, and transmission devices in automotive chassis. In the mechanical manufacturing industry, forging is widely applied to the production of components such as ordinary machine tool beds, worktable bases, casings, and gearbox housings in medium and small-batch production.

Casting, on the other hand, is more suitable for manufacturing large and complex metal parts, such as engine cylinder blocks, compressor cylinder bodies, locomotive wheels, gearboxes, bearing seats, and equipment bodies. Casting can produce parts with complex shapes without significant limitations, and casting products have lower costs and higher production efficiency, making them suitable for mass production. Additionally, casting is widely used in the production of precision complex thin-walled small cross-section parts made of heavy and medium-thick steel plates, such as steering knuckles and brake drum inner cavities in automobiles, main reducers, and differential gears.

In summary, forging and casting have their own characteristics. Forging focuses on improving the mechanical and physical properties of metals and is suitable for applications that require high material performance. Casting, on the other hand, focuses on producing parts with complex shapes, especially intricate cavity blanks, and has a wide range of readily available raw materials at lower prices. In practical applications, they each have unique advantages and application ranges. In modern industrial production, it is necessary to choose the appropriate manufacturing process based on the specific requirements and characteristics of the workpiece.
