Vacuum metalizing is an effective way to shield enclosures and components from interference waves coming into or out of the device. This method has the added benefits of creating a uniform layer that does not accumulate inordinately large build-ups or deposits. Additional benefits include:

• The ability to achieve a precise aluminum coating density anywhere from .5-20 microns thick
• A lower cost per part when compared to conductive painting or metal plating
• An environmentally friendly process when compared to conductive painting or metal plating

In some instances, conductive painting is the better solution for EMI/RFI shielding, which is why we offer conductive paint coating services as an alternative to vacuum metalizing. Benefits of our painting process include:

• No part size limitations when compared to vacuum metalizing, which due to the vacuum chamber is limited to a maximum size of 24” by 60”
• Additional clear coats for abrasion and chemical resistance, which can be applied as a topcoat for vacuum metalized coatings
• The ability to achieve maximum shielding protection while still maintaining a conductive coat.

Our metalizing and spray coating pretreatment processes ensure that all coatings have excellent adhesion to prevent peeling and flaking.

Vacuum metalizing and conductive painting for shielding is utilized in multiple applications across a broad range of industries, including:

• Medical
• Aerospace and Defense
• Contract Manufacturing
• Automotive

A variety of industry leaders have turned to Mueller for our vacuum metalizing and conductive painting services for EMI/RFI/ESD shielding. Some of the major clients we serve include:

• Raytheon
• Boeing
• UTC
• Motorola
• MOOG Medical
• General Dynamics
• Ericsson
• Northrop Grumman
• BAE
• Federal Mogul

Vacuum metalizing can also be used as a vapor barrier against both oxygen and moisture for protecting moisture sensitive marine, military, electronic and telecommunications equipment.
