PCABS high PC grade temperature
Fenómeno do problema
【Problem Phenomenon】High PC content PC/ABS follows general temperature, insufficient filling
Análise das causas
The higher the PC content, the higher the viscosity and the higher the required temperature; high PC ratio grades such as 70/30 need melt temperature at the 260-280℃ upper limit; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based on experience alone
Solução
High PC ratio grades take the upper limit of the temperature window; if flowability is still insufficient, select a high-flow grade; special debugging for thin-wall parts; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Conclusão principal
High PC ratio PC/ABS temperature relies on the upper limit, insufficient flowability means changing the grade; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for similar problems later
