Surface defect amplification in ABS electroplating
Fenómeno do problema
After electroplating of electroplating-grade ABS, pitting, blistering, and poor coating adhesion appear, with a high defect rate.
Análise das causas
Silver streaks, stress marks, mold release agent residues, and moisture bubbles on the injection molded surface are amplified during electroplating; uneven roughening leads to poor coating adhesion; defects on the '2079851475616104452 end will erupt concentratedly on the electroplating end.
Solução
①Strictly dry electroplating-grade ABS and avoid using mold release agents; ②eliminate '2079851475616104452 defects such as silver streaks/bubbles before electroplating; ③standardize the roughening—neutralization—predipping process; ④store the products moisture-proof and pollution-proof; ⑤do coating adhesion verification.
Conclusão principal
The appearance of ABS electroplated parts is determined by the '2079851475616104452 front end: electroplating is an 'amplifier', and no '2079851475616104452 defect can be hidden; no mold release agent, strict drying, and stress control are the three iron rules of electroplating-grade ABS.
