Every sheet-metal part that could be stamped could also, in principle, be laser cut. The question is never which process is better in the abstract — it is which one is right for your volume, your geometry and your tolerance for programme risk.
Here is how we work through it when quoting.
The basic economics
Laser cutting has essentially no setup cost and a relatively high cost per piece. Every part takes the same cutting time as the one before it.
Progressive die stamping inverts that. The die is a significant upfront investment — weeks of tool room time and real money — but once it exists, parts come off the press in a fraction of a second each.
Plot those as two lines and they cross. Below the crossover, laser wins. Above it, the die wins, and keeps winning by a widening margin.
Where the crossover actually sits
There is no universal number, and be sceptical of anyone who gives you one. It moves with:
- Cut length per part. A part that is mostly a simple outline cuts fast on the laser. A part with forty holes and an intricate profile takes far longer, which pushes the crossover down — the die looks attractive at lower volumes.
- Number of operations. If the part needs cutting, forming, piercing and trimming, a progressive die does all of it in one press stroke. Laser cutting only replaces the cutting step; you still need the forming operations separately.
- Material thickness. Thicker material cuts more slowly on the laser, again favouring the die sooner.
- Die complexity. A simple blanking die is a modest investment. A twelve-station progressive tool with cam-actuated forms is not.
As a rough orientation for a typical automotive bracket: below a few thousand pieces a year, laser is usually right. Above twenty or thirty thousand, a die usually pays back inside the first year. The band between is where the real analysis is needed — and where the other factors below tend to decide it.
Geometry that rules one out
Some decisions are made for you.
Laser cannot form. It cuts flat profiles. Any bend, draw, emboss or louvre needs a press operation regardless. For a deeply drawn part, the laser is only ever preparing the blank.
Some features are impractical to laser cut. Very small holes relative to material thickness are a common example — as a general rule, holes smaller than the material thickness get difficult, and the edge quality deteriorates.
Very thick material. Our fibre laser cuts HR steel to 25 mm, which covers most structural sheet work. Beyond that, the process changes.
The factor people underweight: programme risk
Here is the argument we make most often, and it is not really about cost.
A die is a commitment. Once it is cut, a design change is expensive — sometimes it means a new tool. If your design is still moving, if the customer has not frozen the specification, or if the volume forecast is genuinely uncertain, committing to hard tooling early converts a design risk into a financial one.
Laser cutting keeps your options open. It costs more per piece, but a revision costs nothing but a new file.
We routinely recommend a hybrid path for exactly this reason: run the first production batch on the laser while the die is being built. The programme starts on time, real parts reach the customer, and if a change comes through in that window it costs a drawing revision instead of a die rebuild. Because our tool room and our laser are in the same company, this costs nothing to coordinate.
Lead time
A die takes weeks to design, build and try out. The laser can produce parts within days of receiving a file.
If your programme timing is tight, that gap decides the question on its own — at least for the first batch.
A decision path
Rather than a formula, here is roughly how the conversation goes when we quote:
- Does the part need forming? If yes, you need press work regardless. The question becomes whether the blank comes from the laser or from the die.
- Is the design frozen? If no, lean toward laser until it is.
- Is annual volume above roughly ten thousand pieces, with a multi-year programme? If yes, the die is very likely to pay back — ask for both quotes and compare over the programme life, not per piece.
- Is the timing tight? Start on the laser, build the die in parallel.
- Is the part geometry laser-friendly? Small holes in thick material, or a very high feature count, push toward the die.
Ask for both numbers
Whichever way you are leaning, ask your supplier to quote both routes with the tooling cost stated separately. Any manufacturer who can do both should be willing to show you the crossover for your specific part — and if the honest answer is that your volume does not justify a die, you want a supplier who will say so rather than sell you one.
We quote it both ways as a matter of course. Send us your drawing with the annual volume and we will show you where the lines cross.
