PC Injection Machine Screw Wear Acceleration
문제 현상
After processing glass fiber reinforced PC, the screw and check ring wear quickly, and metering fluctuates.
원인 분석
Glass fiber strongly wears metal, and ordinary nitrided screws have a short service life; after wear, plasticizing and metering become unstable, and product quality fluctuates.
해결 방법
①Use bimetallic/hardened screws and barrels for GF-PC; ②Regularly check the check ring clearance; ③Monitor the trend of plasticizing time changes.
핵심 요약
Glass fiber material must be equipped with a wear-resistant plasticizing system.
