ABS mold temperature 50-80

The 50-80°C of ABS mold temperature and high-gloss 60-90°C are standards; the 60°C lower limit and 90°C upper limit are boundaries; balance optimizes quality and efficiency.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

ABS glass fiber orientation type warpage

GF-ABS orientation-type warpage is broken by 'gate design', not by hard pressing with cooling: once the warpage direction is fixed, you should go back and review the gate and orientation, rather than repeatedly trying mold temperatures.

ABS nozzle drool and cold slug marks

ABS drool and cold slug marks often have the 'same source': for drool, first lower the nozzle temperature and add suck-back; cold slug marks rely on the cold slug well to catch the front cold material; both point to nozzle temperature and cold material management.

ABS mold sticking (difficult demolding)

For ABS mold sticking, first 'reduce pressure and temperature', then 'repair the draft angle and polishing', and finally deal with vacuum adsorption; the polishing quality along the demolding direction often affects the demolding feel more than the draft angle.

ABS brittle cracking——product structure stress concentration

A sharp corner in the ABS structure is the starting point of a crack: rounded corners, uniform wall thickness, and reasonable reinforcing ribs are the three structural means to prevent brittleness; many 'material brittleness' cases are actually mines buried by the design, and must be removed from...

ABS brittle cracking——draft angle and insert problems

ABS's draft angle and insert preheating are often overlooked: insufficient draft angle plus forced ejection = cracking, no insert preheating = interface stress cracking; these two details of structural parts must be fixed at the design stage.
