Unstable Weight of EVOH Injection Molded Products
Sorun Belirtisi
EVOH injection molded product weight fluctuates ±3%, exceeding the ±1% precision requirement
Neden Analizi
Shot volume unstable, screw back position inconsistent; holding time fluctuation; feeding amount unstable; EVOH density variation ±2%
Çözüm
1) Displacement sensor to precisely control screw back position; 2) Stabilize holding time and pressure; 3) Precisely set V/P switchover point; 4) Inspect density differences between batches
Temel Çıkarım
Product weight stability depends on shot volume precision and holding consistency
