Tiger-skin-like stripes appear on the product surface
Sorun Belirtisi
Tiger-skin-like stripes appear on the product surface, regular or irregular color bands alternately distributed, affecting appearance
Neden Analizi
Injection speed suddenly fast and slow, melt front unstable
Mold temperature fluctuation
Melt viscosity changes (temperature fluctuation or moisture change)
Improper gate design produces unstable flow
Holding pressure switchover too early
Çözüm
Stabilize injection speed, adopt multi-stage speed control
Ensure the mold temperature is constant in the 40-80°C range
Control barrel temperature and raw material moisture stable
Optimize gate design, use fan gate
Delay the holding pressure switchover timing
Temel Çıkarım
Tiger-skin stripes require stable injection parameters and mold temperature
