Vacuum metalizing came into the business around 1960 as an extended industry. The process of vacuum metalizing was initially intended for the use of interior fittings and accents for vehicles like dashboards, instrument panel, head lights, arm supports, and others. 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.
At present when the automotive industry has progressed, the vacuum metalizing has too in its development. Through vacuum metalizing, fine metal finishes are created that will last for a very long time and the looks are absolutely stunning. With the evolution of the car industry, the world’s leading car manufacturers are even changing their process from electroplating to vacuum metalizing because of the many factors that it gives like cost effectiveness, health advantages for workers, durability and others.
Considering this process would give your products that extra shine and polish. Note that the other process like chrome plating is not only expensive but is also found to use hazardous acid that is carcinogen.
It is actually very simple to conduct the metalizing process. The coating material is first placed in the container, then in order to purify the air, a special filtering unit is required to make sure that there will be no particles that will reach the surface of the final product as the coating process is taking place. With the use of a pump, temperatures are controlled during the vacuum coating, and throughout the whole process, an application chamber is being used.
So basically, with your chosen metallic finish, the product where you want this coat to be placed on to is positioned in the application chamber. The vacuum chamber is made up of two slots namely the entry slot and the exit slot. 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 through the help of the air vacuum that there is uniformity in the spreading of the coating on the products. The permission of air and material into the application chamber is through the entry slot, and the exit slot would thrust the air outwards directing on the item to be coated.
Vacuum metalizing can be conducted on various finished products like those made of glass, plastic, metal, ceramic and even paper. While you are plating and coating for your product needs, you will save the environment and your money too if you use vacuum metalizing.
