Why Inconsistent Material Flow Is Costing You
Learn how stable feeding and accurate dosing improve quality and reduce costs.
When a moulded part fails a drop test, comes out with colour streaks, or shows a few grams of shot-to-shot variation, the first questions asked are almost always about the machine. Injection speed. Melt temperature. Back pressure. Mould design. Cooling profiles.
These are all worth checking. But before any of them come into play, one fundamental factor quietly determines whether the process is stable at all:
How consistently material flows into the machine.
Most moulders assume material flow is stable. It rarely is. In fact, it is one of the most underestimated sources of variation on the factory floor and one of the easiest to fix once it is understood.
What do we really mean by material flow?
