PCL uneven shrinkage
Sorun Belirtisi
PCL products shrink unevenly, with poor dimensional accuracy and large shrinkage differences between different parts.
Neden Analizi
PCL has a slow crystallization rate and uneven shrinkage; wall thickness differences; uneven cooling; molecular weight distribution; processing parameter fluctuations.；During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
Çözüm
①Uniform wall thickness design; ②Uniform cooling control; ③Stable process parameters; ④Mold compensation design; ⑤Dimensional inspection.；After adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Temel Çıkarım
PCL shrinkage management is the prerequisite for dimensional accuracy; uniformity is the core; testing verifies the actual situation.；After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
