After EAA material changeover, the first 5-10 products contain residue of the previous raw material, color difference and performance deviation
Análise das causas
Large amount of previous raw material residue in the barrel and screw; incomplete cleaning, residue in dead corner areas; insufficient amount of purging material
Solução
1) Increase the amount of purging material to 2-3 times the barrel capacity; 2) Increase the speed and temperature during purging to accelerate removal; 3) Disassemble the screw to thoroughly clean dead corners
Conclusão principal
Changeover residue is caused by incomplete cleaning; thorough cleaning and disassembly are the key
