Every temperature decision on the line assumes the thermocouples are telling the truth. They drift. A zone reading 10°F low is silently running 10°F hot, degrading polymer and generating the gels that quality will spend the next month investigating.
The steps ChatterFix schedules for this PM. Every step is a checkable item on the work order — a technician can speak their way through it without touching a keyboard.
Every temperature decision on the line assumes the thermocouples are telling the truth. They drift. A zone reading 10°F low is silently running 10°F hot, degrading polymer and generating the gels that quality will spend the next month investigating.
Recipes that stop being reproducible, gels that appear without a material change, and burned-out heater bands that go unnoticed because a neighbouring zone compensates.
Quarterly verification against a calibrated reference. Verify immediately after any heater band or thermocouple replacement.
This procedure — and every other PM for your industry — is already built into ChatterFix. Pick your industry and it lands on the right equipment, on the right interval, in about three minutes.
