Horning: A horning die provides an arbor or horn which the parts are place for secondary operations.
Hydroforming: Forming of tubular part from simpler tubes with high water pressure.
Pancake die: A Pancake die is a simple type of manufacturing die that performs blanking and/or piercing. While many dies perform complex procedures simultaneously, a pancake die may only perform one simple procedure with the finished product being removed by hand.
Piercing: The piercing operation is used to pierce holes in stampings.
Transfer die: Transfer dies provide different stations for operations to be performed. A common practice is to move the material through the die so it is progressively modified at each station until the final operation ejects a finished part.
Progressive die: The sheet metal is fed through as a coil strip, and a different operation (such as punching, blanking, and notching) is performed at the same station of the machine with each stroke of a series of punches.
Shaving: The shaving operation removes a small amount of material from the edges of the part to improve the edges finish or part accuracy. (Compare to Trimming).
Side cam die: Side cams transform vertical motion from the press ram into horizontal or angular motion.
Sub press operation: Sub-press dies blank and/or form small watch, clock, and instrument parts.
Swaging: Swaging (necking) is the process of "necking down" a feature on a part. Swaging is the opposite of bulging as it reduces the size of the part. The end of a shell casing that captures the bullet is an example of swaging.
Trimming: Trimming dies cut away excess or unwanted irregular features from a part, they are usually the last operation performed.
Pillar set: Pillar set are used for alignment of dies in press movement.
