PMMA Silver Streaks (Gas Streaks)
Sorun Belirtisi
Silver streaks on the product surface, mostly occurring near the gate.
Neden Analizi
Vaporized moisture or volatiles follow the melt filling and leave streaks on the surface; insufficient drying, excessive melt temperature decomposition, and poor venting all induce them.
Çözüm
①Strengthen drying; ②Lower the melt temperature; ③Increase back pressure for venting; ④Improve mold venting.
Temel Çıkarım
Silver streaks = check three: moisture + decomposition + venting.
