Case Study: Custom Silicone Rubber Band for Precision Masking in Electroplating


Welcome to the AFAC Custom Masking Program! Today, we are excited to present a unique solution designed to meet the specific needs of one of our customers. This case study highlights the development and application of a custom large silicone rubber band used for masking a band around a cylindrical object during the electroplating process.

The Challenge

Our client, a manufacturer in the electroplating industry, faced a challenge in achieving a precise and liquid-tight seal around cylindrical objects during plating. The existing solutions often allowed plating solutions to seep underneath the masks, resulting in imperfect finishes and increased rework, leading to higher production costs.

Our Solution

To address this issue, AFAC designed a custom large silicone rubber band with the following features:

  1. Elasticity for a Snug Fit: The silicone rubber band is highly elastic, ensuring a snug fit around the cylindrical objects. This elasticity makes the band easy to install and remove, improving the efficiency of the masking process.
  2. Chamfered Edges: The band features chamfers on either side, which provide a liquid-tight seal. These chamfers are crucial in preventing plating solutions from seeping underneath, ensuring a clean and precise finish.
  3. Durability and Reusability: Made from high-quality silicone, the band is durable and can be reused multiple times without losing its elasticity or effectiveness, further reducing costs for the client.

Implementation and Results

The custom silicone rubber band was integrated into the client’s electroplating process with significant success. Here’s how it made an impact:

  • Precision Plating: The chamfered edges ensured that the plating solution did not seep under the mask, resulting in a precise and consistent plating finish.
  • Reduced Rework: The improved sealing and precision reduced the need for rework, lowering production costs and increasing throughput.
  • Ease of Use: The elastic nature of the band made it easy for workers to install and remove, speeding up the masking process and enhancing overall productivity.
  • Cost Efficiency: The durability and reusability of the silicone bands provided long-term cost savings, making the solution both effective and economical.

Client Feedback

The client expressed high satisfaction with the custom solution provided by AFAC. They noted the significant improvement in the quality of their electroplating finishes and the reduction in production costs due to decreased rework and enhanced efficiency. The ease of use and durability of the bands were also highlighted as major benefits.


This case study demonstrates AFAC’s commitment to providing tailored solutions that address specific manufacturing challenges. By designing a custom silicone rubber band with precise features, we were able to help our client achieve higher accuracy and efficiency in their electroplating process.
