Manufacturers implement metal forging and die casting processes to shape metal parts into desired shapes. However, it is true that both of these processes are quite different from one another.
The type of metal shaping process used by manufacturers depends on the particular metal part they need. If you have a good knowledge of die casting and metal forging processes, then it will be a lot easier for you to decide which process is the right choice to shape a certain metal.
Metal forging process is actually a classic method of shaping metal parts into desirable shapes. You might be familiar with the image of a blacksmith striking at a sword on an anvil with the help of a hammer. This is a classic example of metal forging process.
The blacksmith has now been replaced by a high-tech hammering machine, thanks to the technological advances in the field of die casting. The anvil has also been replaced by a part die, but the process is almost the same. In metal forging process, manufacturers use a machine to force the heated metal part into an open die until it transforms into the desired shape they want.
One of the major reasons why manufacturers prefer metal forging to other metal shaping process is that the finished product acquired through metal forging is a lot denser and mechanically strong. In addition to that, they are also highly resistant to wear and force. However, a few cavity defects usually happen in the metal forging process.
On the other hand, die casting is a modern and technologically advanced metal shaping process. In this process, the metal part is melted and forced into a closed die until it cools into the preferred shape. Manufacturers prefer die casting to other metal shaping process because this process is a lot less expensive.
In addition to that, die casting process is also a lot more efficient. Manufacturers are able to produce numerous metal parts within a short amount of time. There are also no or relatively fewer cavity defects in the finished product obtained through die casting process.
If you are planning to shape alloys into desired shapes, then we highly recommend you to choose die casting process. This is because it is a lot more easier to cast alloys through this process.
