Periodic surface corrugation of PU
문제 현상
Periodic corrugations on PU product surface with spacing of 5-15mm
원인 분석
Periodic fluctuation of injection speed; unstable hydraulic system; unstable screw speed
해결 방법
1) Overhaul injection system to stabilize pressure and speed; 2) Servo motor drive replacing hydraulic drive; 3) PID control to stabilize injection parameters
핵심 요약
Corrugation is caused by unstable injection; equipment overhaul and PID control are key
