Increasing Awareness and Understanding About Vaccum Metalizing

Vacuum metalizing refers to the process of evaporating aluminum or any other metals inside a vacuum chamber that bonds into the desired substrate for achieving a uniform metallized layer. Vaccum metalizing is also called thermal evaporation which is the most common physical vapor deposition process for metal alloy application under vacuum. When it comes to vacuum metalizing, it has many uses like decorative chrome, RFI/EMI shielding, metallic finishes, heat shielding, light reflectors for highly reflective coatings, and vapor barriers. Go to  to get started.

The process starts with custom tooling fixtures fabrication, holding and masking your parts in painting and vacuum metallizing operations. Tooling fixtures must provide superior efficiency both in fixture handling, and fixture components. Before being released to production, tooling fixtures are properly inspected following customer guidelines and adhering to strict high-quality standards to ensure that parts are processed correctly. Operators must wear gloves when loading the parts to prevent contaminants from being transferred to the parts being loaded. To make sure that defects are resolved, individual parts are loaded into the tooling fixtures. Masking should be integrated with the tooling fixtures for minimizing manual processes, and any masking that cannot be achieved using a tooling fixture should be completed prior to processing. For reflective and decorative applications, it is important to apply a base coat or primer for proper adhesion and for a smoother surface to assure good quality surface for the finishing or metallizing steps. Basecoating is required for chrome, reflective, and metallic coatings which are not needed for RFI/EMI shielding. After applying paint, the tooling fixtures are then placed into convection ovens for curing the paint. Visit website for more info - go ahead and click!

For the vacuum metalizing process, the fixtures are placed into Carouses which are moved into a vacuum chamber, and once a predetermined vacuum level is reached, the source of evaporation is sent by the current. A tungsten filament is what it makes up the source which is loaded with aluminum or alloy, and the current is used in heating the filament until evaporation of alloy, forming a cloud vapor, bonding its parts. Alloy evaporation is a process which requires line of sight so that the tooling fixtures would rotate in front of the sources of evaporation for achieving a uniform coating. Ont he final stage of the metalizing process, there is the unloading of tooling fixtures and the chamber is returned back to the atmosphere.
