Process comparison
Progressive dies form shallow, high-volume parts from a strip with the carrier web intact; deep drawing moves the material into a cavity and is chosen when the part is deeper than it is wide.
A progressive die keeps the part attached to a carrier web and moves the strip station by station: blank, pierce, form, bend, trim, separate. Material utilisation is high because the strip is used efficiently and the web supports every station. Depth is limited by how much forming the strip can take while still being carried.
Deep drawing starts from a separate blank, which is pulled into a cavity by a punch. Depth is the point of the process, but material utilisation is lower because the blank must contain the full surface area of the finished part.
| Progressive die | Deep drawing | Transfer press | |
|---|---|---|---|
| Feed | Strip on carrier web | Separate blank per stage | Part carried by transfer fingers |
| Best for | Shallow, high-volume parts | Deep housings, sleeves, cups, shells | Multi-operation parts with heavier walls |
| Material utilisation | Highest | Lower — the blank must cover the part | High — no carrier web waste |
| Typical volume fit | Above ~50,000 pcs | Any volume, tooling decides the route | Roughly 20,000–500,000 pcs |
| Tooling cost | Highest | Medium | Medium to high |
| Depth capability | Limited by the carrier strip | Depth is the objective | Good, with several forming stages |
| At Balford | Yes | Yes, up to Ø250 mm | Yes, up to 350 t |
Choose progressive tooling when the part is flat or shallow, volume is high, and cost per piece dominates. The die is expensive but it runs fast and wastes little material.
Choose deep drawing when the part needs depth and a seamless wall — a solenoid housing, a sensor shell, a can or a sleeve. If the geometry also requires holes, slots or trimmed edges, those become stations or secondary operations, but the depth still comes from drawing.
When a part needs several forming operations but not the material efficiency of a carrier web, transfer tooling can be cheaper than a big progressive die and more capable than a single-operation line. Balford runs transfer press stamping up to 350 t — see transfer press stamping.
We compare the three routes against your drawing, the annual volume and the tolerances that matter. The output is not a generic recommendation but a specific stage sequence, tooling concept, estimated press tonnage and the inspection plan — see the prototyping and first article page for how the route is proven before serial production.
Below roughly 10,000 pieces a single-operation die is usually cheapest, and the deep draw route is normally competitive because the tooling is simpler than a progressive die. The crossover point depends on the number of forming operations the part needs.
Yes, progressive dies can include drawing stations, and we evaluate that route when volume justifies it. It only works when the strip can carry the part through the drawing stages without the carrier web interfering with material flow.
When the part needs three or more forming operations, has a larger diameter or heavier wall, and annual volume is roughly 20,000 to 500,000 pieces. Transfer tooling avoids the carrier web and usually costs less than an equivalent progressive die.
