Technical guide
A progressive die is the right choice when the part can remain attached to the strip until the last station and quantities are medium to high; a transfer die is suited to medium-to-large parts or parts with deep forming, which must be separated from the strip and moved between stations by gripper systems.
Quick answer
A progressive die is the right choice when the part can remain attached to the strip until the last station and quantities are medium to high; a transfer die is suited to medium-to-large parts or parts with deep forming, which must be separated from the strip and moved between stations by gripper systems.
In a progressive die, the strip advances with each press stroke through several stations (blanking, piercing, bending, forming, optional tapping) and the finished part is separated at the last one. In a transfer die, the part is blanked at the start and transferred between stations by a gripper system.
| Part size | Small/medium → progressive; medium-to-large → transfer |
|---|---|
| Forming depth | Limited → progressive; deep drawing → transfer |
| Annual volumes | High → progressive (one part per stroke); medium → either |
| Scrap | The progressive die requires a carrier strip; the transfer die can optimise the blank layout |
| Press | The transfer die requires suitable presses or gripper systems |
Since 1969, we have been designing and building sheet metal dies in Rosà (VI): feasibility study with the customer, 3D CAD design, construction in our own toolroom and tryout with dimensional inspection. UNI EN ISO 9001:2015 certification by TÜV SÜD.
It depends on the part: a transfer die includes the gripper system, but it can reduce scrap and enable forming operations that a progressive die does not allow.
Yes, typically in progressive dies with tapping units.

Bean Force
Up to 10× the force of a spring, from the bottom up, in a few centimetres. For press tools, high-pressure valves, seismic dissipators for racking and steel structures and wherever more force is needed.
