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. There are a number of roles that vacuum metalizing does. They include metallic finishes, shielding and decorative chrome. Thermal evaporation or Physical Vapor Deposition is the process that is used to apply metals under a vacuum. Below are stages of vacuum metalizing process.

Tooling Phase

The very first procedure is the fabrication of tooling fixtures that hold and mask the various parts during the vacuuming and painting process. During this stage, tooling fixtures are supposed to offer proper efficiency in the number of components which will result to the best possible piece price.

Loading Stage

The next step is inspecting tooling fixtures and then releasing them to production. In this process, the client is the boss because anything being done ought to be according to their own preference. The client sets guidelines that are followed through the processing of those components. Wearing of gloves is a must when loading the components so that there are no contaminants transferred to the components. 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 Stage

Basecoating is a very crucial process since it helps to ensure that the end product is of top quality. It promotes adhesion which results to a smoother surface. This a measure that is only taken for reflective finishes . Six-axis robotic paint cells and automatic conductive paint cells are examples of the methods that are utilized to perform the practice of coat.

Vacuum Metalizing Procedure

During this stage, the tooling fittings are placed into Carousels that are pushed into the vacuum chamber. What follows next is current being sent to the source of evaporation. The origin is usually a tungsten filament that’s packed with aluminum. The filament is then heated to a stage that the alloy evaporates and then creates a cloud of vapor that bonds together with the parts. After the process of metalizing is done with, the room is taken back to the air.

Topcoating Procedure

The significance of a topcoat are that it enables moisture, chemical resistance and abrasion. There are unique topcoats that apply to different software. The topcoats responsible for the golden, metallic matte finishes and bronze effect are dyed and tinted topcoats. For effective results, work should be done in a clean environment and organized manner.

The Inspection Stage

Inspection Is whereby the pieces are checked if they’re appropriately done According to the instructions made by the client. There’s a database which tracks if there were errors during the process and finally tracking tags are set up for tractability purposes.
