Refer to dies that perform pressing for multiple functions and processes.
Workpieces are transferred with a material feeder into a die one after another with a pitch between processes for each press cycle. The workpieces are then transferred with materials connected to them and are automatically and consecutively processed.
Because many processes are performed with one die using this structure, precision progressive dies are difficult to design and process and expensive to manufacture. On the other hand, they can process workpieces rapidly and are suitable for mass-production.
