In the 1960s, there came about an extended industry on vacuum metalizing. 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.
And now when the industry of automotive has progressed so much, so has the vacuum metalizing too. 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.
This process is considered as the best option especially if you want to give your products the 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.
Actually the metalizing process is quite 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. With the use of a pump, temperatures are controlled during the vacuum coating, and throughout the whole process, an application chamber is being used.
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. The liquid coating is pumped into the application chamber by manual method, and in the chamber is where the converting of the liquid is happening with the aid of the vacuum.
With the aid of the air vacuum, the coating is uniformly spread 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.
