Progressive stamping die is a process that produces complex parts from a metal strip by using a series of dies. Each die performs a different operation, such as cutting, bending, forming, and coining. Progressive stamping die has many advantages for complex parts production, such as efficiency, quality, consistency, and versatility. It can perform multiple operations in one pass, which saves time and energy. It can produce complex parts with high precision and accuracy, which ensures quality. It can produce uniform parts with minimal variation, which ensures consistency. It can produce different types of complex parts with the same set of dies, which ensures versatility.
