Mold and Die Preventive Maintenance Log — Appliance and Foil Tooling
This Mold and Die Preventive Maintenance Log records cleaning, wear checks, lubrication, cycle counts, and refurbishment decisions for appliance and foil tooling between runs. Use it to catch damage early, keep tooling repeatable, and decide when to rework or retire a mold or die.

Overview
This template is a preventive maintenance log for injection molds and stamping dies used in appliance and foil production. It gives maintenance and tooling teams a repeatable place to record cleaning, wear measurement, lubrication, cycle counts, and refurbishment decisions between production runs.
Use it when tooling condition affects part quality, press uptime, or changeover reliability. It is especially useful for high-use molds and dies that need the same checks every time they come off the machine, or for tools that have a known service interval based on cycles or calendar recurrence. The log helps you separate normal wear from defects that need rework, and it creates a clear record of what was verified before the tool returned to service.
Do not use this as a substitute for a full root-cause investigation after a major failure, a design change record, or a formal calibration procedure. It is also not the right template for one-off repair work that needs engineering approval before release. If the tool is already damaged beyond routine maintenance, the log should capture the finding and disposition, then hand off to repair, quality review, or retirement. The value of the template is in making routine checks consistent, independently verifiable, and easy to trend over time.
Standards & compliance context
- Documented preventive maintenance supports OSHA-style equipment safety expectations by showing that tooling was inspected before return to service.
- Traceable inspection records help quality systems demonstrate control over product-forming equipment used in regulated manufacturing environments.
- If your site uses formal maintenance procedures, this log should mirror the approved SOP and not replace required sign-off or lockout steps.
- Any defect that could create a safety hazard, scrap risk, or unapproved product condition should be treated as a blocking finding until cleared.
General regulatory context for orientation only — verify current requirements with counsel or the relevant agency before relying on this template for compliance.
How to use this template
- 1. Set the recurrence and scope for the specific mold or die, including the cycle-count trigger, the production line, and the checklist items that apply to that tool family.
- 2. Assign a DRI for the inspection and define who performs the verification step, especially if one person records findings and another clears the tool for return to service.
- 3. Run the checklist after the tool is removed from production, recording each item as yes, no, or N/A with measurements, photos, or notes where a defect is found.
- 4. Mark any blocking issue that prevents reuse, create the follow-up maintenance or repair task, and note whether the tool can be returned to service after correction.
- 5. Review repeated findings at the end of the service window to decide whether the tool needs refurbishment, tighter inspection intervals, or retirement.
Best practices
- Write each checklist item as a single, observable action such as verifying a vent is clear or measuring wear at a named location.
- Record cycle counts at the time of inspection so you can compare service intervals against actual tool usage.
- Separate blocking defects from non-blocking findings so minor cleanup does not hide a condition that should stop the next run.
- Use the same measurement points every time on the same mold or die to make wear trends comparable across inspections.
- Attach photos of damage, burrs, galling, or residue before the tool is cleaned so the original condition is preserved.
- Keep lubrication checks specific to the lubricant type, application point, and confirmation method instead of writing a generic 'lubricated' note.
- Escalate repeated out-of-tolerance findings to refurbishment or retirement instead of resetting the log and hoping the issue disappears.

Common use cases
Frequently asked questions
What does this mold and die preventive maintenance log cover?
It covers the routine checks that keep injection molds and stamping dies ready for the next production run: cleaning, wear measurement, lubrication, cycle count review, and refurbishment notes. It also gives you a place to flag tooling for rework, repair, or retirement when a defect crosses your acceptance limit. This template is meant for between-run maintenance, not for full teardown or engineering change control.
How often should this log be used?
Use it after each production run, after a defined cycle-count threshold, or on a scheduled recurrence such as weekly or monthly depending on tool criticality and usage. High-wear tooling may need a log entry every time it comes off the press or molding machine, while lower-use tools can be checked less frequently. The right cadence is the one that catches wear before it becomes scrap, downtime, or a safety issue.
Who should run this maintenance log?
A tooling technician, maintenance mechanic, or mold/die setter usually owns the checklist, with a DRI assigned for sign-off and follow-up actions. Production operators may record the handoff condition, but the verification step should be completed by someone qualified to judge wear and lubrication condition. If your site separates maintenance and quality, this log can also be reviewed by QA before the tool returns to service.
Is this template useful for compliance or audit readiness?
Yes, because it creates a traceable record of preventive maintenance actions, inspection results, and disposition decisions for tooling that affects product quality and equipment safety. It supports the kind of documented control expected in regulated manufacturing environments, especially where repeatability and defect prevention matter. It is not a substitute for your site’s formal SOPs, but it helps prove they were followed.
What are the most common mistakes when using this template?
The biggest mistake is writing vague checklist items like 'tool looks good' instead of independently verifiable checks such as measuring wear or confirming lubricant coverage. Another common issue is skipping cycle counts, which makes it hard to predict when a mold or die is due for service. Teams also sometimes mark every issue as critical, which hides the few findings that really require immediate blocking action.
Can I customize this log for different tooling types?
Yes, and you should. Appliance injection molds may need cavity inspection, vent cleaning, and ejector pin checks, while foil stamping dies may need cutting-edge inspection, alignment checks, and burr removal. Keep the checklist item wording specific to the tool family so the log stays short, clear, and easy to verify.
How does this compare with ad-hoc maintenance notes?
Ad-hoc notes are easy to start but hard to trend, audit, or hand off between shifts. This template standardizes the same checklist items every time, so you can compare wear over time, spot recurring defects, and decide when a tool is drifting out of tolerance. It also makes it easier to separate blocking issues that stop production from non-blocking findings that can wait for the next service window.
Can this log connect to other systems or workflows?
Yes, it works well alongside CMMS work orders, spare-parts requests, quality holds, and production scheduling. A failed verification step can trigger a maintenance task, a Kanban-style priority change, or a block on the next run until the tool is cleared. It also pairs well with asset histories so you can see how often a specific mold or die needs rework.
