Pre-treatment for gold plating
The process involves steps like sulfuric acid treatment, recovery, rinsing, ultrasonic treatment, electrolytic oil removal, acid washing, alkaline copper treatment, burnt copper treatment, etc. It's done using advanced fully automated machines.
Acid copper
The acid copper plating process deposits copper onto metal surfaces, creating a base layer for adhesion and smoothness. It enhances conductivity, appearance with gloss, and offers corrosion resistance.
Electrolytic protection
Electrolytic protection prevents corrosion by depositing a protective metal layer on the surface, enhancing durability and resistance to environmental factors such as oxygen and moisture, thereby significantly extending the metal's lifespan.
