Metalizing is a general term used for all activities that involve spraying non-metallic surfaces with metallic coating. The first instance of this process took place in 1835 during mirror making. In fact mirrors were the first products to be made through this method. This process takes place in a special chamber in a controlled environment because the temperatures are normally very high.
The metal to be used as the coating is heated to its boiling point inside a vacuum chamber. When the metal boils, it forms fine droplets on substrates placed inside the chamber under it. When it cools, it forms a superior coating on the substrate that cannot be peeled off easily. Heating in the vacuum chamber is done using an electron beam, plasma heating or resistance heating. Los Angeles metalizing experts have several variations of this method in use.
One of the variants of this technique requires substrates to be heated in the place of metals. Here, the metals melt down and form even coatings on substrates which are usually heated to extremely high temperatures. The substrate involved must be able to withstand high temperatures without undergoing deformation for the method to work effectively. Superiority of resultant coatings and energy efficiency of this technique are making several companies to shift to this method.
Proper surface preparation is however necessary before beginning the process in order to promote the resultant bond between coating metals and surfaces. One of the methods that have stood the test of time in cleaning such surfaces is abrasive blasting. It eliminates all forms of dirt, mould, metal oxides, and old paint on surfaces exposing the interior surface.
There are several benefits linked to using metallization to coat surfaces as compared to the other methods. First, it has a higher ability in lessening surface corrosion from various agents. Applying heavy the coating heavily covers surfaces completely and protects them from corrosion. The cover prevents the interior of substrates from being affected by abrasive agents. Pipes used in water that moves fast a perfect example. The pipes are protected from abrasion by plating them with tough metal materials.
A substrate that is vacuum metalized is very suitable for use as an insulator. This is primarily because of the enhanced reflectance properties. A perfect example is in aircrafts. Thermal insulation systems that are used in spacecrafts are made of several layers of vacuum metalized polyimide films. There are also several applications in commercial and residential settings. Metallization makes a surface better by enhancing its properties.
Metallization also enhances barrier properties. For example, metalizing a plastic substrate makes it a better barrier to moisture and air. This is a very important application in food and packaging industries. Since the metalized surface also has lower light transmission capability, it also forms a better light barrier. Common cases of functional barrier and insulation applications are in medical packaging, window treatment, electronic labels, and radiant barrier insulation.
Another reason for applying this process on surfaces is aesthetics. It adds a unique appearance to substrates making them reflective like mirrors. Different colors can also be incorporated in the process to make products appear even better. Some of the main applications in the world of beauty lie in merchandizing, personal care packaging, label stocks, and appliance surfacing film.
