Poor electroplating adhesion of styrene-acrylonitrile copolymer ABS products
ظاهرة المشكلة
After ABS products are electroplated, the plating adhesion is poor, and blistering or peeling easily occurs.
ABS is the most commonly used electroplating plastic.
تحليل الأسباب
(1) Product surface roughness is unsuitable, affecting the roughening effect
(2) Product internal stress is large, affecting plating adhesion
(3) Improper processing temperature, with uneven material structure
(4) Release agent residues affect electroplating
(5) The ABS grade is not suitable for electroplating
الحل
(1) Select electroplating-grade ABS grades
(2) Optimize processing temperature within the 200-260°C range 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 styrene-acrylonitrile copolymer, control mold temperature at the higher value within the 50-90°C range
الخلاصة الأساسية
ABS electroplating quality is closely related to material grade and internal stress.
