Graco Precision Shot Meter (PSM) Dispense Systems
Description
The Graco Precision Shot Meter (PSM) is a high-accuracy, single-component metering and dispensing system designed for automated assembly. It features an innovative first-in-first-out (FIFO) fluid path and robust construction, making it ideal for dispensing one-component epoxies, silicones, acrylics, urethanes, polysulfides, and thermal interface materials (TIMs).
With its compact and lightweight design, the PSM system can be easily integrated into robotic arms or motion tables without overloading them, providing repeatable accuracy that meets the demanding needs of automotive, electronics, and telecommunications manufacturing.
Features
- High Precision and Repeatability : The integrated servo motor control ensures a shot repeatability of ±1%, delivering highly consistent material application and minimizing waste.
- Patented FIFO Fluid Path : The innovative “First-In-First-Out” (FIFO) design eliminates dead zones where material could accumulate and cure, significantly reducing maintenance and downtime caused by clogs.
- Ultra-Wear Resistant Construction : Available with ceramic (CER) internal components to withstand abrasive fillers and high-wear applications, ensuring a longer service life even with challenging materials.
- Flexible System Integration : Designed for easy automation, supporting seamless PLC integration with multiple communication protocols, including I/O, Profinet, and EtherNet/IP.
- Lightweight and Compact Design : The optimized weight and size allow for easy mounting on robotic arms or motion tables without exceeding payload limits, enhancing production flexibility.
- Advanced Temperature Control : Offers both ambient and warm-melt configurations (up to 70°C / 158°F) to ensure optimal material viscosity and flow characteristics for various applications.
- Wide Material Compatibility : Engineered to handle a broad range of single-component materials, from low-viscosity resins to high-viscosity pastes (up to 1,000,000 mPa·s).
