Inaccurate metering caused by screw check ring wear
ظاهرة المشكلة
Product weight fluctuates greatly and the injection volume is unstable
تحليل الأسباب
The clearance between the check ring and the barrel inner wall increases due to wear, causing material leakage; glass fiber or fillers accelerate wear
الحل
Regularly check the check ring clearance (new <0.05mm, scrap >0.15mm); replace worn check rings in time; select wear-resistant check rings
الخلاصة الأساسية
Check ring performance directly affects product weight consistency and process stability
