Electroplating issues often have a few typical causes. Keeping the current stable with a good electroplating rectifier can help avoid many of these problems. Use the following steps to identify and correct them.
- Poor Adhesion
Check cleaning and activation—oils or oxides can block bonding.
Avoid high current and sudden surges; start with low current. A electroplating rectifier with smooth current output helps the initial layer adhere properly.
Contamination? Use Hull Cell testing and carbon treatment if needed.
- Rough or Gritty Deposits
Remove debris: inspect anode bags, filters, and tank sludge.
Balance bath chemistry: replenish additives and check metal concentrations. Stable electroplating rectifier performance reduces uneven deposition and surface roughness.
- Dark or Dull Areas
Boost throwing power: adjust conductivity salts.
Check additive levels; low-current zones may require special brighteners.
Remove metallic impurities via low-current electrolysis. Precision electroplating rectifiers improve throwing power for corners and recesses.
- Pitting
Use wetting agents and improve agitation.
Treat organic contamination with carbon filtration. Consistent voltage from a electroplating rectifier minimizes gas entrapment and pitting.
Workflow for Troubleshooting
- Document the defect.
- Check operational parameters.
- Analyze bath composition.
- Treat contamination last. A reliable electroplatingrectifier ensures all steps operate under stable electrical conditions, supporting high-quality plating.
