Runner cross-section, length, and layout design unreasonable

문제 현상

원인 분석

Runner cross-section too small, large resistance, difficult filling Runner too long, large pressure loss, short shots at the end Unbalanced runner layout, filling differences between cavities Improper runner cold slug well design, cold slug enters the cavity Unsmooth transition between runner and gate, producing turbulence

해결 방법

Increase runner cross-section to reduce resistance Shorten runner length to reduce pressure loss Balance runner layout to ensure uniform filling of each cavity Reasonably design cold slug wells to prevent cold slug Smooth transition between runner and gate

핵심 요약

Runners need balanced layout and appropriate cross-section
