The versatility of the Graco HFR Metering System is sure to re-define automotive NVH (noise, vibration, harshness) applications. It's modular design, combined with Graco technologies and precision dispensing capabilities provide automotive manufacturers with a system that is advanced, reliable and affordable.

The Graco HFR Metering System for NVH Foams is an affordable alternative to traditional RIM systems. It is a standard configured product, not a custom-built machine. A lower initial investment allows manufacturers to use acoustical foam applications where it may not have been possible before.

  • More technology at a lower initial investment
  • Compact - smaller footprint saves valuable space
  • Lower cost of ownership - horizontal pumps can be rebuilt at your facility
  • Advanced controls monitor the system
  • Precision shots, repeatable dispensing
