Environmentally Friendly Metal Finishing TechniquesUpdated: February 14, 2022
As eco-friendly processes have become more important than ever, the metal finishing industry has developed new methods for plating and finishing that benefit both the customer and the planet. These green processes work at the high-performance level you would expect during application and use while giving you peace of mind that you’re not harming the environment.
Top Environmentally Friendly Metal Finish Techniques
There are many green finishing processes in the metal finishing industry, including:
Anodizing is a finishing process that converts the metal substrate into a durable, corrosion-resistant and decorative anodic oxide finish. Applying this finish to the substrate is similar to the process of highly controlled oxidation. As a result, the anodic oxide is fully integrated into the substrate, making it impossible to peel or chip. Anodizing works well for nonferrous metals such as aluminum, titanium and magnesium, and it preps the surface for other processes, including sealing and coloring.
Anodizing is an environmentally friendly process as it uses an aluminum alloy, a versatile and durable metal. It does not use any RCRA heavy metals or VOCs and easily complies with federal and state environmental regulations. The anodic oxide finish offers other benefits, too, such as reduced friction, increased lubrication and insulation.
Powder coating is a dry and free-flowing powder that does not need a solvent in the mixture. It is applied electrostatically, and after being cured with heat, the powder coating acts like a skin on the substrate. It is a popular metal finishing choice because of its durability and cost-effectiveness.
Experts consider powder coating to be an eco-friendly finishing process. It does not produce harmful compounds, and the raw materials are safe. You can even apply powder coating indoors, so there is minimal risk of air pollution.
Apart from its green qualities, powder coating offers many benefits, such as:
- Simple application process
- Less exhaust emitted, which lowers heating and cooling costs
- Can be saved and reused
- No waste disposal equipment necessary
Eco-Friendly Alternatives to Electroplating
Though electroplating is popular, it is not considered a green process. Technological advances have created environmentally conscious alternatives to electroplating that achieve the same results. One of these processes is physical vapor deposition (PVD).
PVD is a powder coating that does not use hazardous materials or create harmful waste. Its clean application process meets environmental protection standards. It is applied by vaporizing a solid material in a vacuum, then deposited onto the substrate as a coating. PVD provides high performance and is incredibly durable with the capability to take on your desired characteristics, such as thickness.
