What Is a Die Casting Die? 

The die casting manufacturing technique of parts involves applying high pressure to force molten metals into a mold known as a die. These dies help cut the metal into the necessary parts and make it the correct size. The process is relatively fast and economical because it can be used on the same or different metal sheets once the die is made. 

Definition 

Die casting die refers to both the die that is used in die casting as well as the parts that are produced from the die. Die casting is a relatively new process still being developed, and new ideas are being adopted.
