Which EMI / RFI Shielding Method Is Right For Your Part?

Both vacuum metallization and conductive spray coatings deliver engineering-grade EMI/RFI shielding for plastic enclosures and electronic components. The right process depends on your part size, geometry, production volume, attenuation requirements, and manufacturing goals.

VACUUM METALLIZED
EMI SHIELDING

Greater than 60 dB EMI attenuation using ultra-thin aluminum coatings. Multi-metal stack-ups achieve even higher shielding performance while minimizing thickness and weight.

>60 dB

EMI Attenuation

0.5 – 20 microns

Coating Thickness

High-Volume

OEM Production

Lightweight

Thin Coatings

BEST FOR

High-volume OEM plastic enclosures where appearance, consistency, and repeatability are critical.

CONDUCTIVE SPRAY
COATINGS

Flexible conductive coatings for complex, oversized, or non-standard parts. No line-of-sight limitations make the process suitable from prototype through high-volume production.

40–80 dB

EMI Attenuation

5–25 μm

Coating Thickness

Any Size

No Chamber Limit

Scalable

Production Ready

BEST FOR

Large, irregular, or complex parts requiring flexible production and maximum design freedom.
