PCF Metering System
Precision Continuous Flow Metering and Dispense System
Advanced closed-loop technology assures a precise, continuous flow of material
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
For drivetrain gasketing, the Graco Dispense Analyzer helps you find and correct the smallest of errors – before your customers find them for you.
Features :
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
