Poor electroplating adhesion of methyl styrene-acrylonitrile copolymer ABS products
Sorun Belirtisi
Poor coating adhesion after electroplating of ABS products, prone to blistering or peeling.
ABS is the most commonly used electroplating plastic.
Neden Analizi
(1) Unsuitable product surface roughness, affecting roughening effect
(2) Large product internal stress, affecting coating adhesion
(3) Improper processing temperature, uneven material structure
(4) Residual mold release agent affecting electroplating
(5) ABS grade not suitable for electroplating
Çözüm
(1) Select electroplating-grade ABS grades
(2) Optimize processing temperature within the 220-280°C range, reduce internal stress
(3) Do not use mold release agent or use easy-to-clean type
(4) Product surface annealing treatment (60-80°C, 2h)
(5) Methyl styrene-acrylonitrile copolymer controls mold temperature at the higher value within the 60-100°C range
Temel Çıkarım
ABS electroplating quality is closely related to material grade and internal stress.
