Abstract
There is described a method and system for regulating an extrusion process by obtaining a first thickness at a first position along an extrudate as material is extruded through a die gap of a die; comparing the first thickness with an expected thickness of the extrudate at the first position to obtain a value for an error, the expected thickness modeled in real-time using a size of the die gap as input; and varying the size of the die gap when the error exceeds a threshold to compensate for the error. There is also described a method and system for determining an expected thickness of a material during an extrusion process.
