Key Applications of Rectifiers in the Surface Treatment Industry

• Electroplating: Providing precise current control for processes such as copper plating, nickel plating, zinc plating, chromium plating, and precious metal plating, ensuring coating uniformity and adhesion. Stable power output is crucial in high-precision electroplating applications in aerospace, automotive, and electronic connectors.
• Anodizing: Widely used in aluminum alloy surface treatment, including architectural aluminum materials, automotive parts, and electronic product housings. Liyuan Haina rectifiers provide reliable power support for processes such as sulfuric acid anodizing, hard anodizing, and coloring.
• E-Coating: Providing high-current DC power for electrophoretic primer processes on automotive bodies and parts, ensuring corrosion resistance and uniform coverage of the coating.
• Electropolishing and Surface Treatment: Providing high-quality DC power for electropolishing and deburring processes on stainless steel and other metal materials, improving product surface finish.

Liyuan Haina invites partners, new and old customers from the global surface treatment industry to visit the SUR/FIN 2026 exhibition, meet with our team face-to-face, and learn how Liyuan Haina rectifiers can provide more efficient and reliable power solutions for your production line.
