Why does one die ship the next day while another of the same size waits four days? The answer never sits in a single line item; it is the sum of drawing preparation, revision rounds, die complexity and the workshop queue that week.
Lead time is not one duration — it is four stages added together
A cutting die passes through drawing preparation, laser cutting of the die board, rule bending and assembly, then rubbering and final checks. Laser cutting is usually the shortest stage; what really drives the schedule is getting the drawing production-ready and the hand work of bending and assembly.
That is why the honest answer to “how many days for a die?” cannot be given before seeing the file. A simple carton die arriving with a production-ready drawing and a multi-window display die measured from a photo do not move on the same calendar.
- Laser cutting time is a small share of the total lead time.
- Bending, assembly and rubbering are hand work and grow with complexity.
- A production-ready file is the single strongest input for a firm date.
The biggest variable: file clarity and revision rounds
A job arriving as a clean, dimensioned PDF, AI or DXF can reach drawing approval the same day. A job arriving as an unmeasured sketch, a low-resolution photo or an old sample first needs measuring and redrawing, then your approval — and every day spent waiting for approval is added to the delivery date one-to-one.
Revision rounds work the same way: a dimension change after production has started can scrap an already-cut board and already-bent rules. In that case the lead time is not extended — it restarts.
- Every day waiting for approval is added directly to the delivery date.
- A revision after production starts can reset the schedule to zero.
- A written confirmation that the latest file is final is the cheapest insurance.
Die complexity and material supply
The number of inner windows, tight-radius turns and the length of creasing and perforation lines directly extend bending and assembly. Standard 23.8 mm rule and 18 mm die board come from stock; a special rule height, a different edge hardness or special profile rubber adds supplier time to the schedule.
Corrugated board, gasket material and PVC/PET need a different rule and rubbering setup than a standard carton job. On these jobs, late material information means the right rule is ordered late.
- More windows and turns mean more hand-work hours.
- Non-standard rule and rubber add supplier lead time to the date.
- Material details in the first message let supply run parallel to production.
The workshop queue and urgent-job planning
The workshop’s queue that week is a variable independent of your job’s technical hours. On urgent work the queue can be reordered, but the sequence of drawing, approval, production and checking is never skipped — speed must not come before the die running correctly on the machine.
The most useful piece of information on an urgent request is a clear answer to “when, at the latest, must it be in your hands?”. An hour-level target lets the workshop plan the queue realistically, and hand delivery instead of courier can win back the last day.
- Asking about the current workshop load gets you a realistic date, not an optimistic one.
- Urgent jobs need the latest acceptable date and hour stated explicitly.
- The courier-versus-pickup choice can save a full day on a tight schedule.
Quote details we clarify together
When the file, material, quantity and deadline are clear, the quote conversation moves faster and with less back-and-forth.
- Current revision file
- Material and quantity details
- Critical dimensions or production notes
- Deadline expectation and delivery preference
