ABS brittle cracking——improper screw plasticizing parameters

ABS screw parameters should be 'moderate': the speed and back pressure are not the higher the better, shear heat is an invisible degradation source; using the actual melt state as the criterion is more reliable than memorizing the parameter table.

ABS brittle cracking——unreasonable temperature parameters

ABS temperature is a 'double-edged sword': too low causes under-plasticization brittleness, too high causes degradation brittleness; set the range according to the grade, adjust the rear section according to the regrind, and judge by the melt state rather than the displayed temperature, only then...
