Metal Plating

AOTCO's Finishing Techniques

Since the earliest days of metal usage thousands of years ago, people have needed to manage and adjust the characteristics of their metal creations. In modern times we employ a number of metal finishing techniques and technologies that continue this age-old endeavor. Whether you are looking for increased physical strength, a highly reflective surface, or just an aesthetically pleasing finish, there are a wide range of surface finishing options for your metal (or non-metallic) components. 

One of the most common forms of surface finishing is electroplating. It involves the electrodeposition of one material onto the surface of another, often resulting in a physically and chemically stronger material. Another common surface finishing process is chemical anodizing, which creates an oxide layer within the surface of a metal substrate. This layer provides great physical protection against wear, but it is also very porous making it great for dying and other forms of color application.

At AOTCO, we specialize in a multitude of finishing processes such as electroplating and electroless plating, chem films, passivation, electropolish, and a variety of chemical anodizes.

Benefits of Metal Finishing

Due to the variety of surface finishing processes, there’s also a long list of potential benefits that can be granted from an effective surface finish. 

While the benefits of each surface finish is determined by both the substrate and deposited materials, the most common benefit across all surface finishing processes is increased strength and wear resistance, without adding too much weight or dimensional change. This benefit is incredibly vital for our clients in the aerospace industry, who are constantly looking for ways to improve strength without jeopardizing the dimensions of a component. 

Another notable benefit of surface finishing is the completely smooth and sterile surface it can provide to its substrates. This makes surface finishing a highly sought-after process for medical device manufacturers.

Finally, another notable benefit of surface finishing is the aesthetically smooth and customizable finish it can provide for its components. Some surface finishing processes, like anodize, can help with the application of paints or other dyes onto the surface of a substrate, making for a visibly pleasing finishing.
