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

Vacuum metalizing is an effective way to shield enclosures and components from interference waves coming into or out of the device. Mueller Corporation offers vapor-deposited coatings and conductive spray coatings providing a variety of shielding solutions, including:

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

We utilize two different types of vacuum deposition processes in our shielding applications: thermal evaporation vacuum metalizing and PVD sputtering. Our proprietary thermal evaporation vacuum metalizing systems allow us to achieve a precise coating density of up to 20 microns of aluminum.

Our 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

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.

Flexible and Cost Effective Options

Vacuum metalizing and PVD sputtering has the added benefits of creating a uniform layer that does not accumulate inordinately large build-ups or deposits. Additional benefits include:

  • A deposition layer of approximately .5-5 microns thick, as to not accumulate large build-ups or deposits
  • A lower cost per part when compared to conductive painting or metal plating

Because there are certain applications that require conductive coatings we offer conductive painting services, to address all of our clients complex coating needs. Benefits of our painting process include:

  • No part size limitations when compared to vacuum metalizing, which is limited to the size of the vacuum chamber
  • Added clear coats for additional 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.

Functional Spray Coatings

In addition to our conductive spray coatings, we offer Teflon and ceramic functional coatings, which deliver

  • Corrosion protection
  • Abrasion resistance
  • Chemical resistance
  • Electrical insulation
  • Low coefficient of friction
