In order to create a quieter driving experience, many automotive manufacturers are using acoustical foam solutions to prevent road, wind and engine noise from entering the cabin.

In typical noise vibration harshness (NVH) applications, acoustic polyurethane foam is injected into cavities (pillars, cowl bars, rockers, wheel wells and sail panels) where it quickly expands to fill the countour of the empty space.

The foam reduces the noise and vibration, providing a quieter, smoother ride for the driver.

Graco’s solution for automotive NVH
The compact Graco HFR Metering System for NVH Foam is a high quality meter, mix and dispense system that offers more technology and functionality – at a lower price than traditional custom systems. It is a
standard configured product, not a custom-built machine. A lower initial
investment allows you to use acoustical foam applications where it may
not have been possible before.
