Product has jetting, weld lines, or surface waviness defects
문제 현상
The product has jetting, weld lines, or surface waviness defects, related to the injection speed setting
원인 분석
Injection speed too fast, producing jetting and excessive shear
Injection speed too slow, producing weld lines and short shots
Unreasonable speed switchover point produces waviness
Single-speed injection cannot adapt to complex cavities
Unstable injection speed causes front fluctuation
해결 방법
Adopt multi-stage speed injection: slow-fast-slow
Adjust each stage speed according to cavity structure
Reasonably set speed switchover points
Avoid too fast initial speed to prevent jetting
Ensure injection system stability
핵심 요약
Injection speed needs multi-stage control to adapt to the cavity
