PMMA Insufficient Cooling Deformation
Sorun Belirtisi
Products deform after ejection, and dimensions stabilize after extending cooling time.
Neden Analizi
PMMA cools slower than PP and ABS; when cooling time is insufficient, ejection strength is low and deformation continues; thick-wall parts need longer cooling.; During on-site troubleshooting, verify item by item according to this mechanism to avoid blindly adjusting the machine based on experience alone.
Çözüm
①Extend cooling time; ②improve cooling efficiency; ③calculate cooling according to wall thickness; ④control ejection temperature within a reasonable range.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability.
Temel Çıkarım
PMMA cycle optimization must not sacrifice cooling sufficiency; for deformed parts, rechecking cooling time is often the most direct solution path.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence.
