Precision in Anodizing for Specialized Electrical Machines
When it comes to the production of specialized electrical machines, such as Brushless DC motors and permanent magnet & hybrid stepping motors, the process can be intricate and demanding. One of the most challenging aspects is the masking process involved in anodizing parts. At Sona SPEED, we understand these complexities and are here to provide insights and tips to help you navigate this process more efficiently.

Understanding the Impact of Complex Masking
Masking is a manual process that demands a high level of precision. While masking flat, smooth surfaces is straightforward, masking a portion of a surface or small, intricate features can be time-consuming. This complexity can lead to higher costs and longer lead times. For instance, a complex masking process can sometimes double the cost of a part.

The Role of Anodizing and Chem Film
Anodizing is a common request we receive, especially from our aerospace and space customers. It provides a durable, corrosion-resistant coating that can withstand significant wear in extreme environments. However, an anodized coating is electrically non-conductive, which can pose challenges when certain features need to maintain conductivity. To address this, we often recommend a chem film coating as an alternative. Like anodizing, chem film seals an aluminum surface and protects it from corrosion and wear. The key difference is that chem film conducts electricity, allowing customers to enjoy the benefits of anodizing without the need for complex and costly masking.

Simplifying Masking Requirements
For customers who require superior durability and wear resistance, and may not have the option of choosing chem film, there are ways to simplify masking requirements. For instance, plugging threaded holes can maintain electrical conductivity more cost-effectively than masking intricate features. Additionally, masking large, smooth, flat surfaces instead of intricate features can also simplify the process.
