In this article we address the problem of current reflection at the contact point between the rack and the part in the zinc electroplating process. This potentially harmful effect can lead to numerous complaints and customer dissatisfaction. We want to take a closer look at the phenomenon and present a solution that can benefit both producers and customers of zinc plating services.

Case Study: Current Reflection at the Contact Point Between Rack and Part

When racks go through the zinc electroplating process, especially when parts with varied surface geometry are mounted on them, current reflection often occurs. This phenomenon can result from uneven current conduction through the metal elements, which leads to uneven zinc coverage and potential gaps in the protective coating.

Causes of Current Reflection

Uneven current conduction: The surfaces of the rack and the part may have different current-conducting properties, which leads to non-uniform current flow and reflection.

Improper mounting: Incorrect positioning of the part on the rack can lead to poor electrical contact, increasing the risk of current reflection.

Excessive current density: Too high a current density can intensify the reflection effect, especially in areas with a large difference in electrical potential.

Solution: Using a Metal Alloy with a Smaller Conducting Surface

To effectively eliminate the problem of current reflection at the contact point between the rack and the part, we propose introducing a special metal alloy with a smaller conducting surface. Thanks to this innovative approach, we minimize the risk of uncoated spots in critical areas, such as the contact points between the hook and the part. This method enables more uniform zinc coverage, which translates into excellent corrosion protection and greater customer satisfaction.

Current Reflection at the Contact Point - Summary

In this article we discussed the problem of current reflection at the contact point between the rack and the part in the zinc electroplating process and presented a solution based on racks made of a suitable metal alloy. We believe that our experience and advanced technologies can help minimize this problem and ensure high-quality services for our customers.
