Below, the ductile iron casting factory will introduce the differences between forging and casting
1、 The difference between forging and casting:
Different meanings:
Forging: Using methods such as hammering to make a metal material in a plastic state into a workpiece with a certain shape and size, and changing its physical properties.
Casting: The process of melting metal into a liquid and pouring it into a mold to obtain the desired shape of the casting after cooling, solidification, and cleaning. It can be made into various objects with complex shapes.
2. Different casting processes:
Forging: It is a processing method that uses forging machinery to apply pressure on metal billets, causing them to undergo plastic deformation to obtain forgings with certain mechanical properties, shapes, and sizes. It is one of the two major components of forging (forging and stamping).
Casting: It is the method of casting liquid metal into a casting cavity that is suitable for the shape of the part, and waiting for it to cool and solidify to obtain the part or blank.
2、 Forging and casting purposes:
Forging is generally used for the processing of forgings of certain shapes and sizes.
Casting is a relatively economical method of blank forming, usually used on parts with complex shapes.

3、 Advantages and disadvantages of forging and casting processing:
Advantages of forged parts:
Forging can eliminate defects such as casting porosity generated during the smelting process of metals, optimize the microstructure, and, due to the preservation of complete metal flow lines, the mechanical properties of forgings are generally better than those of castings of the same material. For important parts with high load and severe working conditions in related machinery, forgings are commonly used, except for simple shapes that can be rolled into plates, profiles, or welded parts.
Advantages of cast parts:
1. It can produce parts with complex shapes, especially blanks with complex inner cavities.
2. Wide adaptability, commonly used metal materials in industry can be cast, ranging from a few grams to several hundred tons.
3. The source of raw materials is wide and the price is low, such as scrap steel, scrap parts, chips, etc.
4. The shape and size of the casting are very close to the parts, reducing the amount of cutting and belonging to non cutting machining.
5. Widely used, 40% to 70% of the weight in agricultural machinery and 70% to 80% in machine tools are castings.
Disadvantages of forged parts:
Trauma accidents that are prone to occur in forging production.
Disadvantages of cast parts:
1. The mechanical performance is not as good as that of forgings, such as coarse structure and many defects.
In sand casting, single piece and small batch production result in high labor intensity among workers.
3. The quality of castings is unstable, with multiple processes and complex influencing factors, which can easily lead to many defects.
