Injection Molding
4 조회수
Inaccurate metering caused by screw check ring wear
문제 현상
Product weight fluctuates greatly and the injection volume is unstable
원인 분석
The clearance between the check ring and the barrel inner wall increases due to wear, causing material leakage; glass fiber or fillers accelerate wear
해결 방법
Regularly check the check ring clearance (new <0.05mm, scrap >0.15mm); replace worn check rings in time; select wear-resistant check rings
핵심 요약
Check ring performance directly affects product weight consistency and process stability
