What is Vacuum metallizing?

First all all, let's see "What is metallizing?""  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.

So, what is vacuum metallizing?  This form of metallization involves boiling the coating metal in a specially designed vacuum chamber and then allowing the condensation to form a deposit on the substrate’s surface. The coating metal can be vaporized via techniques such as plasma or resistance heating.
