EVA cable compound extrusion surface
문제 현상
The cable sheath surface is rough or has gel particles.
원인 분석
EVA cable compound has high requirements for plasticization and filtration; heat sensitivity makes retained material prone to gelation.; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based on experience alone
해결 방법
①Optimize the plasticization temperature; ②strengthen filtration; ③clean the dead corners of the head; ④control the residence time.; after adjustment, take consecutive samples to verify the effect, and resume mass production only after confirming stability
핵심 요약
The surface quality of cable compound relies on plasticization, filtration, and thermal management; cleaning dead corners is the focus.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
