HDPE mold venting
Sorun Belirtisi
HDPE thick-walled parts have trapped air and burning
Neden Analizi
Insufficient venting at the filling end of the thick wall, and air is adiabatically compressed; when troubleshooting on site, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience; this mechanism has been repeatedly verified by industry data and should be confirmed first during troubleshooting
Çözüm
Open vent grooves at the end; vent through insert gaps; reduce the speed at the final stage; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability; change only one variable at a time and record parameter changes, to facilitate locating effective measures
Temel Çıkarım
Thick-wall trapped air is solved by the venting structure; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for similar future problems
