Introduction
Stamping, or pressing, is a manufacturing process where flat metal sheets are converted into complex shapes by applying pressure to certain sections. This process is used to fabricate a variety of components, and can produce parts of increased strength and accuracy.
Stamping is a wide-reaching process, offering four main types: mechanical, progressive, transfer and compound die. Within these types of stamping, there are numerous related terms which can be confusing to keep track of.
In order to help clarify the variety of stamping-related terms, we have compiled a list of definitions below. Use this list as a reference when working with stamping processes.
Mechanical Stamping
Mechanical stamping is the simplest form of stamping, as it uses a single-action press tool and die. The punch applies pressure to the sheet metal, creating a part with a straight edge as well as the desired shape.
Progressive Stamping
Progressive stamping, also known as progressive die stamping, is a process where a single press stroke is used to form, shape and cut multiple parts. Each progressive stamping operation requires its own tool and each step of the process is completed in a single press stroke.
Transfer Stamping
Transfer stamping is a type of progressive die stamping, but with an added capability. Transfer systems move parts from station to station, with each station performing a type of stamping operation. The parts can be moved in a linear or rotary motion.
Compound Die Stamping
Compound die stamping combines two or more dies in the same press. The dies are designed to work together, allowing them to complete an entire operation in one step.
Conclusion
Stamping is a complex process that can be intimidating to properly understand. This list of stamping-related terms is a helpful starting point in educating yourself on the process. As you become more experienced with stamping, you will begin to understand the details of each type, and when they are best applied.
