Surface Treatment & Cleaning

Surface finishing is essential to the performance, durability, and reliability of busbars and metal components. At Connor, we apply in-house and partner-supported treatments to meet strict electrical, mechanical, and cosmetic standards. For busbar connections, tin and nickel plating are critical to maintaining low-contact resistance and long-term conductivity. Powder coating offers an effective insulation method, especially for partial or fully coated busbar surfaces. Our ultrasonic DI water cleaning system improves weldability by removing oils and achieving surface tension up to 70 dynes/cm. Deburring and polishing enhance handling safety and surface quality for downstream processes. By integrating these treatments into our vertical production flow, we eliminate secondary handling, reduce turnaround time, and deliver ready-to-assemble components that meet the demands of EV, energy, and industrial applications.
