Hygroscopic resins absorb moisture from the air, and moisture in the melt flashes to steam during injection. The result is splay, bubbles, and — with engineering resins like nylon or PET — permanent loss of mechanical properties that no downstream inspection catches.
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.

Splay that gets chased with process changes for days, and structurally weak parts that pass visual inspection and fail in service. This is the defect most often blamed on the resin supplier.
Verify dew point monthly at the hopper inlet, not at the dryer outlet. Filters and desiccant condition drive most failures — check both.
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.
