Some metal surfaces in various applications and industries require a smooth polished or mirror-like surface either as a finish or before plating. Metal Polishing and buffing is the process of removing fine particles and surface scratches or abrasions from finished metals. A combination of belt, orbital, and sanding wheels with compounds are used in the buffing and polishing process to achieve the desired finish. Since 2007, Spec Finishing has been a trusted source of metal polishing and buffing. We’ve earned an impeccable reputation in the metal finishing industry from years of quality metal polishing and buffing workmanship, competitive pricing, and and industry leading turnaround times.

Class 1: This is a high geared anodic finish that is mainly used for the exterior building products and other products that are continuously exposed to the outdoors. Class 1 is also more resistant to high traffic areas.

Class 2: A commercial anodic finish that is highly recommended for interior or light exterior applications. These exteriors usually receive regularly scheduled maintenance such as storefronts. It is not as durable or wear-resistant as Class 1.

Best Metals to Plate on Substrates

  • Copper:Well known for its electrical conductivity, copper is a great choice for plating non conductive substrates. A huge benefit to copper plating on plastic is its relatively low cost, especially when compared to other precious metals.
  • Gold:The #1 reason for gold plating is appearance, but it also offers a number of added benefits. Gold plating on plastic can withstand corrosion and is a good conductor of electricity. Golds heat shielding properties make it an easy choice for high temperature applications.
  • Nickel:Due to nickels bright and shiny appearance, it can serve as a durable, and less toxic, substitute for chrome on plated automotive parts. Alloying nickel with other metals such as tungsten or tin can enhance its corrosion resistance properties.
  • Chrome:Providing a smooth and polished chrome finish with good corrosion resistance, chrome is commonly used as a decretive plating on plastic method in the automotive industry.

Below is a standard Polishing & Buff process we use for our parts pre-Plating. This can also apply to Stainless Steel surfaces for a “mirror like” finish.
