Poor Electroplating Bonding Force of acrylonitrile-styrene-acrylate copolymer ABS Products
Problembeschreibung
After electroplating of ABS products, the bonding force of the coating is poor, and blistering or peeling easily occurs.
ABS is the most commonly used electroplating plastic.
Ursachenanalyse
（1）The product surface roughness is not suitable, affecting the roughening effect
（2）The internal stress of the product is large, affecting the coating bonding
（3）The processing temperature is improper, and the material structure is uneven
（4）Release agent residue affects the 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 220-260°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）acrylonitrile-styrene-acrylate copolymer controls the mold temperature to a higher value within the 50-90°C range
Wichtigste Erkenntnis
ABS electroplating quality is closely related to the material grade and internal stress.
