Reduces material waste with superior flow control

Used in conjunction with a material supply system and robotics platform, the Graco PCF Metering System assures a precise, continuous flow of material. Closed-loop technology provides real-time adjustments for changes in material temperatures, viscosities, dispense rates or robot speeds – providing your operation with a highly precise, continuous dispense. System components include: Advanced Display Module, Fluid Plate, Graco CAN Cable and Gateway.

Handles a range of materials:

• Ambient, warm melt and hot melt materials to 400°F (204°C)
• Low to high viscosity materials
• Unlimited volume

 

Graco PCF Metering System

The next generation of precision metering

  • Closed-loop "real-time" control ensures a precise, continuous dispense – improves part quality and reduces material waste
  • Intuitive user interface simplifies setup, reduces training time
  • Integrated USB interface for easy data downloads - allows for further analysis of process data
  • Multiple gun capabilities for additional productivity - lets you program up to four guns
  • Compact modular design - easy to install, integrate and maintain
  • Low cost of ownership - fewer wear parts compared to shot meters
