Compound dies produce a complete blank in one station at every stroke of the press. Basically, these dies perform one or more operations at the same time. For instance, they can blank (cut the outer form) and pierce (cut the inner form) of a shape simultaneously.
For more demanding or complex blanking and piercing applications, a compound die can do the job faster. Rather than handling just one operation at a time, the compound die can simultaneously complete the blanking and piercing processes.
The compound die is less useful for bending and forming operations, and it tends to require a higher level of force than some of the other options. That said, it’s a more cost-effective option than the simple die when it comes to manufacturing washers and other flat metal parts. If you’re looking for types of punches and dies that you can use in general cutting applications, the compound die could be the solution you need.
