Unstable weight of EMA injection molded products
ظاهرة المشكلة
The weight of EMA injection molded products fluctuates ±3%, exceeding the ±1% precision requirement
تحليل الأسباب
Unstable injection volume and inconsistent screw back position; holding pressure time fluctuates; unstable feeding amount; EMA density varies ±2%
الحل
1) Displacement sensor precisely controls the screw back position; 2) Stabilize holding pressure time and pressure; 3) Precisely set the V/P switchover point; 4) Inspect density differences between batches
الخلاصة الأساسية
Product weight stability depends on injection volume accuracy and holding pressure consistency
