ABS burnt marks at flow end
Sorun Belirtisi
ABS burnt marks at flow end, trapped gas adiabatic compression, speed and vent adjustment.
Neden Analizi
ABS burnt marks at flow end; air trapped gas adiabatic compression high temperature; injection speed too fast; poor venting; end converging area; recurrence after machine cleaning.; during on-site troubleshooting, verify item by item according to this mechanism, avoiding blind machine adjustment based solely on experience
Çözüm
①Injection speed reduced in 10% steps; ②vent 0.025-0.05mm; ③end venting; ④machine cleaning; ⑤recurrence monitoring.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Temel Çıkarım
Speed and venting of ABS burnt are the adjustment directions; 10% steps are a fine method; the end is the key area.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
