Vacuum metalizing came into the business around 1960 as an extended industry. At first, vacuum metalizing process was developed only for interior fittings and d?cor of automobiles uses like dashboards, instrument panels, head lights, arm supports, and so on. Top coat application was not included in the process back then, and this would mean the easy scrubbing off of the effect of shiny plate and consequently there was a risk for the fittings to get scratched.
Today, when the car industry has developed a lot, so does vacuum metalizing. With the aid of this process, fine metal finishes are created with the quality that can last for ages and with the beautiful look. As the automotive industry undergoes evolution, leading automotive producers all over the globe have switched from electroplating to vacuum metalizing because they realized several advantages in using this process, from durability to its cost-effectiveness to the health benefits that the workers can derive from it.
Considering this process would give your products that extra shine and polish. Be aware that using chrome plating process is not only costly but also very hazardous since the acid used in this kind of process is a carcinogen.
The process of metalizing is very simple. To start, the coating material is placed in a reservoir, then a special filtering unit is needed so that the air will be purified for this will ensure that no particles will arrive at the surface of the final item while the coating process is undergoing. During the vacuum coating, the temperatures are controlled with the use of a pump, and while the process is going on, an application chamber is used too.
And so imagine the product which you want to be coated with your desired metallic finish, will be placed into an application chamber. The entry slot and the exit slot are what consist of the vacuum chamber. Through manual pumping, the liquid coating is placed into the application chamber, and this is where it is converted into a spray form with the help of the vacuum.
It is the air vacuum that aids in spreading the coat uniformly on to the product. With the entry slot in the application chamber, material and air are allowed entrance while the exit slot thrusts the air outwards on the coated products.
The various finished products that vacuum metalizing can be done are on glass, plastic, metal, ceramic or paper. With the use of vacuum metalizing on your product, you are saving the environment and your money.
