Vacuum Metalizing and Spray Coating Solutions for EMI, RFI, and ESD Shielding

Mueller’s specialized coating processes provide interference protection for even the most challenging components. We offer thermal evaporation vacuum metalizing and PVD sputtering as well as conductive spray painting, providing a variety of shielding solutions, including:

  • EMI shielding (Electromagnetic Interference Shielding)
  • RFI shielding (Radio Frequency Interference Shielding)
  • ESD shielding (Electrostatic Discharge Shielding)

Our multiple pre-treatment processes ensure that all coatings have exceptional adhesion and remain free of flaking and peeling.

Mueller Corporation’s multi-layer vacuum coating process can be used to apply:

  • Copper/Aluminum
  • Cooper/Stainless Steel
  • Copper/NiChrome
  • Custom combinations to meet your unique shielding requirements

Vacuum Metalized and Conductive Paint Shielding

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.
