A measured repair decision for an existing die
Cutting die repair and refurbishment
If the product geometry has not changed, every defect does not automatically require a new die. The board, cutting rule, crease rule and ejection rubber are inspected separately so a localized repair can be distinguished from damage that affects the entire tool.
Which dies can be assessed?
Carton, label, corrugated and custom steel-rule dies do not fail in the same way. A short worn rule section may be replaceable, while a warped or moisture-damaged board requires the complete geometry to be checked. Assessment starts with die photographs, the latest cut sample and the current drawing when available.
- Lines that no longer cut cleanly
- Weak or crushed crease lines
- Broken, hardened or unbalanced ejection rubber
- Loose rule and localized board damage
How is the repair limit decided?
The goal is not to keep an old die at any cost. Critical dimensions and board flatness are checked first. A new die may be safer when the product has been revised, multiple rule zones have lost height or the carrier board no longer holds the intended geometry.
- Compare the current drawing with the die
- Inspect rule height and joints
- Check the crease against the folding result
- Define whether a post-repair test cut is needed
What should you send for a quote?
Before shipping the tool, send two overall photographs, a close view of the affected area and the latest part cut by the die. Always mention a material or product change; settings that worked on the previous stock should not be assumed to work on the new one.
- Full top view of the die
- Close view of damaged rule or rubber
- The defect on the latest cut part
- PDF, AI or DXF revision file when available
Frequently asked questions
1Can every old die be repaired?
No. A new die may be safer if the board has lost its shape, the product dimensions changed or damage affects several critical zones.
2Can only the rubber be replaced?
Yes, when the board and rule remain within the required geometry. Rubber hardness and placement still need to match the material.
3Can you assess a die made elsewhere?
Its construction, size and visible damage can be pre-assessed from photographs; a final decision follows physical inspection.
