ABS unmelted material
Fenómeno do problema
ABS unmelted material, screw design or melt temperature insufficient, plasticization management.
Análise das causas
ABS unmelted material; unsuitable screw design; insufficient melt temperature; poor plasticization; particle residue; BASF Engineering Plastics Guide.; During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Solução
①Screw design optimization; ②increase melt temperature; ③plasticization quality; ④particle inspection; ⑤equipment assessment.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Conclusão principal
Screw and temperature are the main causes of ABS unmelted material; plasticization quality is the core; assessment ensures equipment matching.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
