1.3 Number of stations
Single station dies
Multi-station dies----progressive dies
Single station dies may be :
Combination (a die in which both cutting and non cutting operations are accomplished at one press stroke) or
Compound (a die in which two or more cutting operations are accomplished at every press stroke).
