The extruder is the heart of the line and the asset with the longest lead time on replacement parts. Almost everything that matters about it — screw and barrel clearance, gearbox oil condition, thermocouple accuracy — degrades gradually rather than failing outright, which makes it the clearest case in the plant for interval-based rather than reactive maintenance.
ChatterFix builds these as child assets under extruder, so failure history and PM completions attach to the component that actually failed — not just to the machine.
The failure modes worth designing a maintenance schedule around — in rough order of what they cost when they happen.
Recording that a PM was "done" tells you nothing next quarter. These are the readings that let you see a failure coming — and the reason ChatterFix captures measurements against the asset rather than just completions.
The parts whose absence turns a short repair into a long outage.

ChatterFix builds this asset, its components, and its PM schedule automatically when you pick your industry — then your technicians update it by talking, not typing.
