Different Environment-Friendly Metal Finishing Methods

Eco-friendly processes in the metal finishing sector have become crucial than ever, due to which they have developed new methods for plating and finishing.

FREMONT, CA: The metal finishing industry has introduced new plating and finishing methods that favor both the consumer and the environment as environmentally sustainable practices have become more relevant than ever. These green processes offer the high levels of performance people demand during application and use while also giving companies the peace of mind that they are not harming the environmental.

In the metal finishing industry, there are various green finishing processes, including:

ANODIZING

Anodizing is a finishing procedure that turns a metal substrate into a long-lasting, corrosion-resistant, and aesthetically appealing anodic oxide finish. The method of applying this finish to the substrate is identical to that of highly controlled oxidation. As a result, the anodic oxide is fully integrated into the substrate, making peeling or chipping impossible. Anodizing is a process that prepares the surface of nonferrous metals like aluminum, titanium, and magnesium for other functions like sealing and coloring.

POWDER COATING

Powder coating is a dry, free-flowing powder that does not require the addition of a solvent. The powder coating is applied electrostatically and serves as a skin on the substrate after being cured with heat. Due to its durability and cost-efficiency, it is a standard metal finishing option.

Aside from being environment-friendly, powder coating has a range of advantages, including:

• Less exhaust emitted, which lowers heating and cooling costs.

• No waste disposal equipment necessary.

• Simple application process.

• It can be saved and reused.

ECO-FRIENDLY ALTERNATIVES TO ELECTROPLATING

Despite its popularity, electroplating is not a green operation. Environment-friendly alternatives to electroplating have been developed as a result of technological advancements. Physical vapor deposition (PVD) is one of these processes.

PVD is a powder coating that uses no harmful materials and creates no waste. Its eco-friendly application process complies with all environmental regulations. It is applied by vaporizing a solid material in a vacuum and then depositing it as a coating onto the substrate. PVD is a high-performance, extremely durable coating that can take on the required qualities, such as thickness.
