Rapid mold cavity corrosion
Problembeschreibung
Rust spots or pitting appear on the mold cavity surface
Ursachenanalyse
PP slightly degrades during processing producing acidic small molecules; the surface treatment agent of the glass fiber contains corrosive components; electrochemistry accelerates corrosion in high-temperature humid environments
Lösung
Select corrosion-resistant mold steels (such as S136, H13 and other high-quality steels); hard chrome plating or nitriding treatment on the mold surface; strengthen daily rust prevention maintenance of the mold
Wichtigste Erkenntnis
Mold corrosion not only affects product appearance but may also contaminate the product
