Mold Repair Work Order Template
A repair work order keeps mold problems from being lost between shifts. This template captures the symptom, the cause, the repair and the checks done before release, and exports to PDF or Word for your mold history file.

Mold Repair Work Order Template
Mold Repair Work Order
Work order: MR-2026-0187 Mold: M-0388 Part: Housing cover Opened: 2026-10-20 Priority: High, next run at risk Shot count at removal: 412,300
Problem Reported
Flash on parting line near cavity 3. Ejector pin 14 sticking intermittently.
Root Cause
Worn shutoff on cavity 3 and varnish buildup on pin 14 bore.
Repair Performed
Reground and welded shutoff, polished bore, replaced pin 14, cleaned vents.
Parts and materials: 1 ejector pin, weld wire, polishing compound Labor hours: 9.5 Technician: J. Rivera
Verification Before Release
| Check | Result | Initials |
|---|---|---|
| Parting line fit and shut off | ||
| Ejection and slides move freely | ||
| Water lines leak tested | ||
| Cavities cleaned and protected | ||
| First shots acceptable |
Approvals
Update the mold history record, including shot count and any dimensional change, when the work order closes. A larger repair, such as a steel change, should trigger a first article inspection.
Tie mold history to ERP assets
Optional: review how repair history and shot counts could live against a tool asset in your ERP.
Optional. The tool and every export work without this. No spam.
How to use this template
Open a work order the moment a mold is pulled. Fill the header with the mold, part, priority and the shot count at removal. Describe the symptom as the operator saw it, then record the cause and repair once the toolroom has opened the tool. Complete the verification table before anyone signs it, and keep the closed order with the mold record.
- Record the shot count at removal
- Describe the symptom in operator language
- Always state root cause, not only the fix
- Verify before release
Why shot count and cause matter
Shot count turns a repair log into a wear history. If the same shutoff wears at a similar count each time, you can schedule preventive work before flash appears. Recording cause also exposes patterns, for example repeated vent clogging that points to a resin or drying issue, not a tooling problem. Without these two fields, a repair log is only a list of jobs.
Verification before returning to production
A repaired mold can fail fast if it is not checked. Confirm parting line fit, slides, lifters and ejection, then pressure test water circuits before the tool goes to the press. After installation, confirm the first shots against the process sheet and compare key dimensions if the repair touched the cavity or core. Document these steps so the press operator knows what was done.
- Parting line and shutoff inspection
- Water and hot runner circuit tests
- Cleaning and rust protection
- First shot review against the process sheet
Common mistakes
Closing a work order without a cause is the most common failure. Another is neglecting to update the mold history, so the next technician starts blind. A third is returning the tool to production without a proper test, then repeating the same repair the next week. Treat each work order as part of the mold's permanent record.
Frequently Asked Questions
Who should approve the release?
Typically the toolroom supervisor and a production or quality representative, so both the repair and the first shots are accepted. Follow your own procedure.
How is this different from preventive maintenance?
A repair order responds to a problem. Preventive maintenance follows a schedule based on shots or time. The two should share the same mold history so wear patterns are visible.
Should I log minor touch ups?
Yes if the mold leaves the press or the work affects quality. Short press side cleaning can go on the shift report, but anything that changes steel or components belongs on a work order.
When is a first article needed after repair?
When the repair changes cavity or core geometry, parting line or critical features, or if your customer requires it after any tool intervention. Check your quality agreement.
If mold repairs are currently tracked on paper or in separate files, we can discuss how to tie them to your ERP maintenance or asset records.
