CEF injection weld line strength low
문제 현상
The strength of the CEF injection multi-gate part at the weld line is only 30-40% of the whole
원인 분석
The temperature of the two melt fronts has dropped, resulting in a small diffusion depth of molecular chains and insufficient entanglement; the dispersed phase orientation at the weld line is discontinuous
해결 방법
1) Increase the injection temperature by 10-15°C to increase the diffusion depth; 2) Increase the injection speed to keep the front temperature high; 3) Increase the holding pressure to ensure compaction at the weld; 4) Set an overflow groove at the weld line and cut it off afterwards
핵심 요약
The low weld line strength is caused by insufficient molecular entanglement; high-temperature and high-speed injection and overflow grooves are effective countermeasures
