Electroplating & Surface FinishingPre-Treatment
Process: Pre-plating ultrasonic degreasing and acid pickle — removes oil, smut, oxide, polishing compound before chrome, nickel, zinc, gold, silver plating and anodising
Critical impact: Contamination directly causes pitting, blistering, and peeling of the plated deposit
Configuration: Multi-tank line: alkaline degreasing → rinse → acid pickle → rinse → plating
Recommended frequency: 28–40 kHz; alkaline degreaser or acid pickle per step
