The Benefits of Metal Polishing

Metal polishing is the process of using abrasive materials to smooth and shine metal surfaces. Whether you work in architecture, automotive, marine, or another industrial sector, it’s important to make metal polishing a part of your process to remove oxidation, corrosion, or other contaminants that might tarnish the appearance of your metal surfaces. Here are a few benefits of metal polishing:

Metal Polishing Is Aesthetically Pleasing

If you’ve ever been tasked with polishing your grandmother’s silver, you probably already understand the aesthetic benefits of polishing metal surfaces. Over the years tarnish (caused by oxidation) can mar the appearance of silver, gold, nickel, chrome, copper, brass, aluminum, steel, or iron plated products.

Thankfully, by using a rough abrasive (such as 60 or 80 grit) followed by subsequent finer abrasives (such as 120 or 180) imperfections such as nicks or scratches can be removed and luster, shine, and even mirror bright finishes can be achieved. Buffing may be required as a final step to get a mirror-bright finish.

Once the metal is polished to a high sheen, protective measures can be taken to prevent future oxidation from taking place—especially important if you’re working with copper alloy products such as brass or bronze. Waxes, oils, or lacquers can be coated onto the surface to maintain that shine over time.

Metal Polishing Works On Cars, Boats, & Buildings

Architectural projects, automotive projects, and marine projects benefit from metal polishing. Decorative finishes for interior consoles, wheel rims, exhaust pipes, faucets, and other hardware or appliances made from metallic elements should be polished to ensure a high-quality sheen.

Bend Plating provides two primary methods of polishing depending on the needs of your project: manual polishing and automatic polishing. Manual polishing is preferred when dealing with complicated geometry or design, or when the project requires a more personal touch. This is especially true for prototypes or small volume jobs which are not well suited to automatic polishing.

Automatic polishing is done via programmed robotics and is best suited to labor-intensive or large-volume jobs in which the polishing process needs to be replicated the same way for a series of parts consistently. Robots complete smooth or grain finishes and are followed by manual processing to ensure the highest of quality. Only 10% of finishing shops offer automatic polishing. We are proud to say that Bend Plating is one of them.

Find Out Which Kind of Metal Polishing Will Work Best For Your Application

Depending on the metals being used in your application, a variety of polishing techniques may be used. Softer metals such as silver and gold require brown, blue, or red cleaning compounds such as rottenstone or iron oxide. Harder metals like nickel and chrome might require harsher compounds such as aluminum oxide. And steel or iron applications may require the use of emery to remove scratches, paints, or rusts.

After polishing, a variety of buffing techniques may be employed to enhance the polish of the project as well as provide mirror bright finishes for those that have need of it. Sisal, Spiral-sewn, loose, Canton flannel, or string buffing wheels provide a high gloss finish guaranteed to give your project the sheen it needs.
