EVA shrinkage rate is unstable
Sorun Belirtisi
EVA product shrinkage rate fluctuates ±0.8%, exceeding the ±0.2% requirement
Neden Analizi
Molecular weight differences between EVA batches cause shrinkage rate changes; processing temperature fluctuations affect crystallinity and thus the shrinkage rate
Çözüm
1) Strictly control raw material batch consistency; 2) Stabilize processing temperature ±2°C to ensure consistent crystallinity; 3) Reserve adjustment space for mold shrinkage compensation
Temel Çıkarım
Unstable shrinkage rate is caused by batch differences and temperature fluctuations; raw material and temperature control are key
