Vacuum Metalizing Procedures
This is the process by which metals are evaporated inside a vacuum chamber which later bonds to produce a uniform metalized layer. Vacuum metalizing boasts of a number of functions. They include metallic finishes, shielding and decorative chrome. Thermal evaporation which is also called Physical Vapor Deposition is the process that is utilized to apply metals under a vacuum. Below are stages of vacuum metalizing process.
The Tooling Process
The first process is the fabrication of tooling fixtures that hold and mask the various parts during the vacuuming and painting process. During this phase, tooling fixtures should offer appropriate efficiency in the amount of components which will bring about the finest possible piece cost.
The Next step is inspecting tooling fixtures and then preparing them for production. During this process, the customer is the boss because whatever is done should be according to their preference. The client sets guidelines that are followed through the processing of those components. Wearing of gloves is a must when loading the parts so that there are no contaminants transferred to the parts. After inspection of the parts is done to ensure that there are no visible defects, loading can now take place onto the tooling fixtures.
Basecoating plays a major role because it ensures that the end product is of top quality. It promotes adhesion and as a result provides smooth surface. This a measure that is only used for reflective finishes . Six-axis robotic paint cells and automatic reciprocating paint cells are examples of those methods that are utilized to do the practice of coat.
Vacuum Metalizing Procedure
Before anything is done in this process, the tooling fixtures are placed into Carousels that are pushed into the vacuum chamber. What happens next is that current is delivered to the origin of evaporation. The origin is generally a tungsten filament that’s loaded with aluminum. The filament is then heated to a stage that the alloy evaporates and then creates a cloud of vapor which bonds with the components. After the process of metalizing is done with, the room is taken back to the air.
The Benefits of a topcoat are that it enhances moisture, chemical resistance and abrasion. There are unique topcoats that apply to different software. The topcoats accountable for the gold, metallic matte finishes and bronze result are dyed and tinted topcoats. For effective results, work should be done in a clean environment and organized manner.
Inspection is the final stage whereby the parts are checked if they are properly done according to the instructions made by the customer. There is a database that tracks whether there were errors during the process and finally tracking tags are put in place for tracebility purposes.
