A repeat order looks safe: the cutting die is on the shelf, the drawing is in the archive, the product is a known one. Yet a small dimension changed in between, a different board batch or worn rubber is enough for the old die not to fit the new product. Revision management on a repeat order therefore asks four questions in turn: is the file the same, is the material the same, is the die still fit for production, and is all of it on record?

Old and new files are compared

Sending only the new PDF is not enough; any changed dimension, lid, hole, crease or product orientation must be marked plainly. The workshop can overlay the two files and look for the difference, but that round takes time and a small change can be missed; circling the changed area on the drawing removes that risk within minutes.

Old and new files are shared together in the same message; the revision date and code go into the file name. Where nothing has changed, that is written too: “same file, die number K-…, quantity …” is the whole of a one-line repeat order and opens no discussion.

  • Old and new files are shared together in the same message.
  • The changed area is marked on the drawing with dimension and direction.
  • Revision date and code go into the file name; if nothing changed, that is stated.

Whether the material is the same is checked

The same drawing gives a different result on a different material: when the grammage changes the crease channel is read again, when the liner changes the cut depth, when the corrugated flute changes the rubber hardness. If material or grammage has changed on the repeat order the old die setting is a starting point, not a guarantee; a short trial cut closes the gap.

A change in lamination, film or adhesive is just as decisive and is noted on the order. Even with the same supplier the lot may have changed; on flexible material (rubber, foam, film) the lot difference affects the dimension and the first part is checked again.

  • The type and supplier of the new material are stated.
  • Any difference in grammage, thickness or liner is written down.
  • A change in lamination, film or adhesive is noted.

The old die is inspected physically

Storage conditions, rule condition and rubbering decide the quality of the repeat run. A board kept in a damp store may have warped, rule that ran a long job may have dulled, rubber may have collapsed or hardened. The old die is therefore checked on a flat surface and by eye before it goes straight into production.

The fault found is usually solved with local repair: rubber is renewed, a short rule section is replaced, the crease line is cleaned. If the board has warped or most of the rules have dulled, a new die is the better choice; the decision is taken with a photo of the die and the last cut part.

  • Bending and dulling along the rule line are checked on a flat surface.
  • Rubbering is inspected for collapse and hardening; it is renewed locally where needed.
  • The board is checked for moisture or impact marks; a photo and the last part are shared.

A recorded revision reduces errors

The most common error on repeat work is old information mixing with the new product: an unapproved draft enters production, or the wrong one of two active files is cut. A written revision record lowers that risk; the approval message is kept, the final file is made unique, the old version moves to the cancelled folder.

The production note is kept with the die: which material, which machine, which pressure it ran at; which nick was enlarged, which rubber was renewed. With that die card the repeat run does not relive the trial and error of the first run and the first stroke gives the right result.

  • The approval message and approved file are kept on both sides.
  • The final file is made unique; the old version goes to the cancelled folder.
  • Material, machine, pressure and maintenance notes are kept on the die card.

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
