Actually it is not like molds. there are several types of dies for forming and cutting anf they act quite differently.
1) is a simple trim die that blanks out a sheatmetal shape.
2) is a simple form die that bends the metal with very little drawing of the metal
3) is a draw die, that actually gets all the metal moving over a mandrel or shaped form.
4) is the most complicated. a progresive die where the triming starts at one end and has multiple stations where the web of metal is moved forward for multple trim, forming or drawing operations.
this is an example of a simple progressive die web.
is an example of a lower half of a progressive die that appears to make a small part that contains trim, form and post form trim sections.
