There is no doubt that both forging and rolling are important metalworking processes that are most commonly used today. In the meantime, both forging and rolling can be used to change the mechanical performance of metal products or metal materials. Moreover, both forging and rolling belong to the category of plastic deformation. But, it should be noted that there are actually many differences between these two types of metalworking processes in a number of aspects. Here we shall primarily make a comprehensive comparison between forging and rolling from the following perspectives.
 
Firstly, forging greatly differs from rolling in terms of forming method. As far as the forming method is concerned, we generally believe that metal products are formed integrally and fitfully in case of forging process. However, in case of rolling process, metal products are formed locally and continuously. In other words, forging process adopts the forming method of integral formation, while rolling process adopts the forming method of local formation. In this sense, we can see that forging and rolling are quite different from each other.
 
Secondly, forging also can be differentiated from rolling by specific application. Basically sand casting gratings technology is mainly used to produce different types of metal products. What's more, these metal products generally can be used for specific applications without later metalworking process. Rolling technology, on the other hand, is primarily used to manufacture different types of general metal materials such as sheet metal, metal strips, metal pipes, metal profiles and metal wires. Obviously, forging technology greatly differs from rolling technology in terms of specific application.
 
Thirdly, there are also great differences between forging and rolling in terms of production efficiency. As far as the factor of production efficiency is concerned, it must be admitted that forging process is of low efficiency. This is because the entire forging process involves a lot of manual work. Besides, forging equipment usually requires manual operation instead of automatic operation. Rolling process, however, is recognized to be highly-efficient. The reason for this is that the entire rolling process greatly depends on automatic equipments. Of course, continuous formation also helps improve the overall efficiency of rolling process.
 
Finally, there exist huge differences between forging and rolling in the aspect of cost. We all know that Forging CNC machining OEM part usually requires some very large forging devices such as forging furnace and forging hammer, etc. Therefore, the cost of forging process is really very high. No wonder that forging industry is considered by many to be big-investment industry. Rolling, however, does not require very high cost since it only requires very small rolling devices.
