PMMA Short Shot
Sorun Belirtisi
PMMA thin-walled transparent parts are underfilled
Neden Analizi
PMMA melt viscosity is high, thin-wall filling resistance is large, and short shots occur when temperature is insufficient; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Çözüm
Take the upper limit of melt temperature and mold temperature; increase injection speed; enlarge the gate; after adjustment, take samples continuously 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
PMMA thin-wall filling requires high temperature, high speed, and large gates; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a reference for troubleshooting similar problems in the future
