What is the difference between forgings and castings?

Castings and forgings are common manufacturing methods of metal parts in the industry. At present, the common metal structures in our lives are basically created by these two methods. Although the uses are similar, there are many differences between the two processing methods, which is why many people wonder. Next, Brishine United Industry Co., Limited will introduce the difference between forgings and castings.





1. The definition is not the same: Castings are metal molded objects obtained by casting with various models, and the obtained objects have certain shapes, sizes and properties. Forging refers to a workpiece or blank obtained by forging and deforming a metal blank.
2. The performance is not the same: There are many procedures in the liquid metal forming of the casting, which makes the quality of the casting not stable enough. Compared with the forgings of the same material, due to the loose structure of liquid forming, the internal defects such as shrinkage and porosity are easy to occur. However, castings can cast parts with complex structures and have stronger mass production capabilities.
3. Different quality: Forgings are of higher quality than castings. Forgings have better mechanical properties than castings, and can withstand large impact forces and other heavy loads. Therefore, forgings are used for all important and stressed parts.
