Electropolishing Services: Enhancing Metal Excellence

At National Plating Company, we specialize in providing high-quality electropolishing services that elevate the beauty and functionality of your metal parts. With a meticulous adherence to industry standards, including the ASTM B912 specification, we assure impeccable finishes and consistent results.

The Electropolishing Process: A Transformation in Metal

Electropolishing is a highly effective metal finishing technique that offers a multitude of benefits. Through a combination of chemical and electrolytic processes, we achieve remarkable improvements in surface finish, durability, and corrosion resistance. Our skilled technicians carefully execute each step of the electropolishing process to ensure precision, consistency, and repeatable results. Electropolishing effectively eliminates surface defects such as burrs, pits, and weld discoloration from metal parts. Our precise and controlled processes remove these imperfections, resulting in flawlessly smooth surfaces that are visually striking. Whether it’s intricate medical devices, aerospace components, or industrial equipment, our electropolishing services breathe new life into your metal parts, giving them a refined and pristine appearance.

Adherence to ASTM B912: Setting the Standard for Excellence

At National Plating Company, we are proud to follow the strict guidelines set forth by the ASTM B912 specification. This industry standard ensures that our electropolishing processes meet the highest levels of quality and consistency. By adhering to ASTM B912, we assure that your metal parts undergo a meticulous and reliable electropolishing treatment, resulting in outstanding finishes.

Unleashing the Potential of Stainless Steel: Improved Ra and Corrosion Prevention

One of the key benefits of electropolishing is the dramatic improvement in the surface roughness, measured as Ra, of stainless steel. By removing surface imperfections and microburrs, we achieve a smooth and pristine finish that enhances both aesthetics and functionality. This reduction in Ra not only enhances the visual appeal of your metal parts but also improves their resistance to corrosion, ensuring long-lasting durability and performance.

High-Quality Finishes: Exceeding Expectations

At National Plating Company, we are committed to delivering high-quality finishes that exceed your expectations. Our experienced technicians utilize advanced equipment and techniques to achieve consistently excellent results. We take pride in our ability to provide precise, reliable, and repeatable outcomes for every project, ensuring your complete satisfaction.
