PA66 short shot comprehensive troubleshooting
문제 현상
PA66 thin-wall parts have intermittent short shots, good and bad with parameters unchanged
원인 분석
Short shot causes are many: poor venting, melt temperature fluctuation, mold temperature drift, non-return ring wear and leakage, intermittency points to equipment state fluctuation; during on-site troubleshooting, verify item by item according to this mechanism, avoiding blindly adjusting the machine based only on experience
해결 방법
Investigate in the order of venting, temperature, non-return ring, and nozzle; detect non-return ring clearance; appropriately widen the process window; after adjustment, take continuous samples to verify the effect, confirm stability before resuming mass production
핵심 요약
For intermittent short shots, focus on checking equipment state rather than process parameters; after confirming effectiveness, fix the parameters and practices into the work instructions to prevent recurrence; include this case in the defect archive as a troubleshooting reference for subsequent similar problems
