Vacuum Metal Coating also know as Vacuum Metallizing is a coating process where extremely thin layers of metal are applied to an object in a high vacuum environment. This process allows the metal layers to exactly copy the shape and contour of the applied object. Vacuum Metal Coating results in in a finish of 0.01 to 0.2 micrometers that has improved resistance to corrosion with a reflexive layer that enhances the surfaces appearance and shine.
Vacuum metallizing is a process very popular for coating small parts, and plastic materials ranging from trophies to sunglasses. Generally we don’t vacuum metal coat items much larger than 12″ x 42″ given the limitations of the vacuum metal coating chamber. The great thing about Vacuum Metal Coating is that there is less polishing needed compared to chrome plating. This minimizes the cost and minimizes hand work as well. The process produces no harmful chemicals.
Thickness and materials
The Metals used in Vacuum Coating range from aluminum, copper, chromium titanium, gold, lead, nickel, platinum, silver, titanium, tantalum and tin.
Thickness of coating application ranges for 0.01 to 0.2 micrometres. When coating a piece it
- changes its conductivity.
- improved corrosion resistance.
- enhanced appearance and luster.
Technology and equipment:
In a high vacuum environment, vapor deposition methods coat products with very thin metal layers. This process allows the metallic coating to exactly replicate the surface of the product resulting in a reflexive layer and decorative metal look very similar to chrome plating.
Vacuum Metal Coating is suitable for:
– products of plastics, laminates and foils
– light metals
– other materials
***: This technology is not suitable for the metal coating of porous-structure materials or for dirty or greasy surfaces.
Aluminum (Al) is the most frequently used material treated with vapor deposition. This technology can also be applied to other pure metals such as copper, nickel, chrome, silver, gold, etc.
Protection of metal coatings:
To improve the service life of metal coatings and the utility properties of products we apply them with surface top lacquers featuring high mechanical and chemical resistance.
