Unstable weight of EAA injection molded products
문제 현상
The weight of EAA injection molded products fluctuates ±3%, exceeding the ±1% accuracy requirement
원인 분석
Unstable shot volume, inconsistent screw back position; holding time fluctuates; unstable feeding amount; EAA density varies ±2%
해결 방법
1) Displacement sensor to precisely control the screw back position; 2) Stabilize the holding time and pressure; 3) Precisely set the V/P switchover point; 4) Inspect the density differences of each batch
핵심 요약
Product weight stability depends on shot volume accuracy and holding consistency
