Abstract
There is provided a method () of controlling melt pressure at a filter outlet () of a melt filter () in an injection unit () having an extruder () that is connectable to a melt accumulator () via the melt filter (), the melt filter () being associated with a target melt pressure range, the method executable at a controller () associated with the injection unit (), the method () comprising: appreciating () an indication of an actual melt pressure associated with the melt filter (); responsive to the actual melt pressure not being within the target melt pressure range, determining () a remedial parameter that is instrumental in bringing the actual melt pressure within the target melt pressure range; releasing () a control signal to execute an action associated with the remedial parameter, thereby causing the actual melt pressure to fall within the target melt pressure range.
