then investigated based on the proposed monitoring methods. It has been found that
lower barrel heating temperature, higher water cooling temperature, and higher screw
will lead to lower specific energy consumption. However, the screw speed has the most
significant impact on overall energy consumption.
High energy efficiency does not mean better melt quality, the effects of barrel
heating, water cooling, and screw speed on the melt viscosity need to be further in-
vestigated to provide substantial guidance on operating point optimization. Heuristic
methods, such as particle swarm optimization (PSO) or differential evolution (DE), can
be adopted to find optimal process settings under specific constraints.
