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 has a number of uses. They comprise metallic finishes, shielding and decorative chrome. Thermal evaporation which is known as Physical Vapor Deposition is the process that is used to apply metal alloys under a vacuum. Explained below are phases of vacuum metalizing procedure.

The Tooling Process

The First step is the fabrication of tooling fixtures which hold and mask the numerous parts through the pruning and painting procedure. During this phase, tooling fixtures should offer appropriate efficiency in the amount of components which will bring about the finest possible piece cost.

The Loading Step

The next step is inspecting tooling fixtures and then releasing them to production. In this process, the client is in charge and whatever is done ought to be according to their own preference. They give instructions which are followed to the latter during the processing of those parts. Wearing of gloves is a must when loading the components so that there are no contaminants transferred to the components. Once review of the components to ascertain that there are no visible defects, loading can now occur on 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 and as a result provides smooth surface. This a step that is only used for reflective finishes . Six-axis robotic paint cells and automatic reciprocating paint cells are examples of the methods that are used to perform the process of coating.

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 which bonds with the components. After the process of metalizing is done with, the chamber is taken back to the atmosphere.

Topcoating Procedure

The Benefits of a topcoat are that it enhances moisture, chemical resistance and abrasion. There are different topcoats that apply to different applications. The topcoats that lead to the gold, metallic matte finishes and bronze result are dyed and sour topcoats. For effective results, work should be done in a clean environment and organized manner.

Inspection Step

Inspection is the final stage whereby the parts are checked if they are properly done according to the instructions made by the customer. There’s a database which tracks if there were errors during the process and finally tracking tags are set up for tractability purposes.
