Notes:
1. Before starting the machine, the extruder temperature must be kept at a constant temperature for about 0.5 hours after reaching the set value.
2. When starting the machine to discharge, the melt temperature should be controlled at about 150-160°C.
3. The recommended filter selection is a 60mesh + 80mesh + 60mesh combination filter.
