Metalizing is a generic name supplied to a thermal spray coating method that uses for coating metal on product covers. Metallization techniques started in 1835.

Thermal spray processes are often referring to as metalizing. Metallic coatings may be decorating, protective or functional. These coatings are also known to be long-lasting, efficient, and highly adaptable.

What Is the Metallizing Process?

Metallization is a general term that refers to the application of a metal coating to another metallic or non-metallic surface. Depending on the desired result, the coating can consist of metals such as zinc, gold, aluminum or silver.

The metallization process can protect the workpiece from damaging external forces (corrosion, wear, weathering, etc.), improve the appearance of the object (giving it a shiny look, for example), or enhance the finished product’s functionality. Industries that use metallization in their manufacturing processes include aerospace, automotive, oil & gas, defense, electrical and many others.

Advantages of the Metallizing Process?

  • Enhanced corrosion protection — Rust is a common issue when working with most metals and especially with steel. Metallization can create a protective coating that inhibits the development of red and/or white rust, increasing the product’s lifespan by as much as 20 years or more.
  • Increased durability — Most metallized coatings are known for their ability to adhere to the surface of the underlying workpiece or substrate. They are less likely to peel, blister, crack or flake than other types of finishes, which increases the substrate’s durability.
  • Providing electrical conductivity — An issue when working with plastic materials is that they do not conduct electricity. Metallizing a plastic surface will enable it to transfer an electric current, which is a vital manufacturing step in the electronics industry.
  • Greater weather resistance — The steel on outdoor structures is vulnerable to the impact of snow, rain, wind and sun over time. Metallization provides a protective coating that creates a barrier between the underlying structure and the elements, which can lengthen the structure’s lifespan and preserve its appearance.
  • Reduced maintenance costs — Painted surfaces will need repainting periodically to preserve the finish. A metallized surface will not require repainting or upkeep, resulting in lower maintenance costs. Like paint, metallized coatings are available in a wide assortment of attractive colors to meet aesthetic requirements.
