Poor Plating Adhesion of Biaxially Oriented Polypropylene Film ABS Products
Problembeschreibung
After electroplating, ABS products have poor plating adhesion and are prone to blistering or peeling.
ABS is the most commonly used plastic for electroplating.
Ursachenanalyse
(1) The surface roughness of the product is unsuitable, affecting the roughening effect
(2) The internal stress of the product is large, affecting the plating adhesion
(3) The processing temperature is improper, and the material structure is uneven
(4) Release agent residues affect electroplating
(5) The ABS grade is not suitable for electroplating
Lösung
(1) Select an electroplating-grade ABS grade
(2) Optimize the processing temperature within the range of 220-260°C to reduce internal stress
(3) Do not use release agent or use an easy-to-clean type
(4) Anneal the product surface (60-80°C, 2h)
(5) For ABS variant, control the mold temperature at the higher value within the range of 50-90°C
Wichtigste Erkenntnis
The electroplating quality of ABS is closely related to the material grade and internal stress.
