Poor Electroplating Bonding Force of acrylonitrile-styrene copolymer ABS Products
Fenómeno do problema
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.
Análise das causas
（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
Solução
（1）Select an electroplating-grade ABS grade
（2）Optimize the 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）acrylonitrile-styrene copolymer controls the mold temperature to a higher value within the 50-90°C range
Conclusão principal
ABS electroplating quality is closely related to the material grade and internal stress.
