The mold decides cycle time, scrap rate, and part quality simultaneously, and it degrades on shot count rather than on the calendar. Vents block first, which traps gas and produces burn marks and short shots; then parting-line wear starts producing flash that no process adjustment fixes.
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.
The mold decides cycle time, scrap rate, and part quality simultaneously, and it degrades on shot count rather than on the calendar. Vents block first, which traps gas and produces burn marks and short shots; then parting-line wear starts producing flash that no process adjustment fixes.
Rising flash and burn defects that operators fight with pressure and temperature, masking the real cause while accelerating the wear. Seized ejector pins and galled slides turn a routine clean into a toolroom repair and days of lost production on that part number.
By shot count, not by date — 250,000 cycles is a common default, with a monthly ceiling so a slow-running tool still gets seen. Abrasive or filled resins and tight-tolerance tools justify far shorter counts. Log the shot count at every service and the tool tells you its own interval.
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.
