Where does the service interval come from?

Use the approved tool maintenance plan or manufacturer requirement. The illustrative interval does not recommend how long your tool can run.

Does the tool need service at the run endpoint?

This plan includes a service when the counter reaches its interval exactly at the endpoint. Reserve that work even if production then stops.

What if service is already overdue?

Review and complete the required service first. This model starts below the recurring interval and does not assume overdue production is acceptable.

Do multiple cavities multiply the cycle count?

No. One molding shot is one machine cycle even when it makes several parts. Use the counter basis specified by the maintenance plan.

Preventive Tooling Maintenance Calculator

Plan the service events due as one tool accumulates production cycles. Enter its approved interval, cycles since service, planned cycles and maintenance labor availability.

What this calculator does

Count cycle-triggered tooling services during a planned run and compare their labor demand with available hours.

Formula used

Services due = floor((cycles since service + planned cycles) ÷ service interval)
Required service labor = services due × labor hours per service
Service labor headroom = available service labor − required service labor
Cycles until next service = service interval − cycles since last service
Ending cycles since service = starting cycles + planned cycles − services due × service interval

Inputs explained

Planned Production Cycles: Machine shots or strokes planned during the production window.
Service Interval: Recurring cycle interval from the approved tool maintenance plan.
Cycles Since Last Service: Current counter reading minus the reading at completed service.
Labor Hours per Service: Total person-hours in the service work instruction.
Available Service Labor: Productive maintenance person-hours available during the same production window.

How to use the result

Best suited to mold service labor Planning, die cycle counter review.
Overdue tools require service review before this planning calculation. Condition, calendar and manufacturer requirements may require earlier service. Total labor availability does not prove each service fits a specific time slot.

Current U.S. benchmarks

The producer price index for plastic resins and materials stands at 280.569 (BLS, Aug 2026), up 6.6% from a year earlier. Quotes priced off last quarter's material cost miss this move.
The U.S. has 14,378 furniture and related products establishments employing about 355,594 workers (Census County Business Patterns, 2023).
