PCABS barrel temperature gradient
Problem Phenomenon
PC/ABS barrel temperature gradient setting, feed 200-220℃ to nozzle 245-260℃.
Cause Analysis
PC/ABS barrel temperature gradient: feed zone 200-220℃, compression zone 220-240℃, metering zone 240-255℃, nozzle 245-260℃; the gradient affects plasticization and degradation; uniformity management.
Solution
①Feed zone 200-220℃; ②compression zone 220-240℃; ③metering zone 240-255℃; ④nozzle 245-260℃; ⑤gradient verification.
Key Takeaway
PCABS barrel gradient is fine temperature control; each section has different functions; verification ensures plasticization quality.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
