1. After the extruder temperature reaches the set value before starting the machine, it needs to be kept constant for about 0.5 hours.
2. When starting the machine to discharge, the melt temperature should be controlled at about 160-170°C.
3. The recommended filter selection is a 60 mesh + 80 mesh + 60 mesh combination filter.
