Do you know how to distinguish forging and casting?

The finished product of casting has a lower density while the finished product of forging has a higher density Therefore, for the same volume: the weight of cast metal is heavier and the strength is weaker; the weight of forged metal is lighter and the strength is much stronger because it has been compressed. Forged products have enough hardness and are not easily deformed. However, even sturdy forged products can be deformed when subjected to strong impact.

Forging and casting are both metal processing techniques, but their principles and applications are different.

• Forging is the process of heating a metal block to a soft state and then changing its shape and size through striking, compressing, or squeezing. During the forging process, the metal undergoes high-temperature and high-pressure processing, which improves its grain structure and enhances its mechanical properties. The advantages of forging include dense products, compact structure, high mechanical strength, and high precision, and it is usually used to produce high-strength, high-quality metal parts, such as car engine parts, aircraft propellers, and tools.

• Casting is a process of melting metal or metal alloys and then injecting them into a mold to cool and solidify into shape. During the casting process, various complex shapes can be produced, and large quantities of products can be produced. The advantages of casting include the ability to produce products of various shapes and sizes, high production efficiency, and low cost. Casting is usually used to produce large quantities of metal parts and products, such as car engine parts, pipelines, building materials, etc.

In summary, forging and casting are both metal processing techniques, but forging is usually used to produce high-strength, high-quality metal parts, while casting is usually used to produce large quantities of metal parts and products.
