WEFILL-SYR-SF003 Single Component Filling Machine – Precision Dispensing for High-Viscosity Materials
Product Description
The WEFILL-SYR-SF003 is a specialized single-component filling machine engineered to handle challenging, high-viscosity fluids, pastes, and materials with powder fillers. Perfectly tailored for 20-liter standard straight-body pails, this system ensures consistent, bubble-free filling for a wide range of industrial adhesives and compounds.
Key Applications
This versatile filling system is compatible with the following materials:
● Silicone and thermal gels
● Silver epoxy and conductive adhesives
● Resin adhesives, UV adhesives, and lubricating greases
● PU adhesives and other thixotropic compounds
Why Choose WEFILL-SYR-SF003?
The WEFILL-SYR-SF003 is designed to address the unique challenges posed by materials with poor flowability. Unlike conventional liquid fillers, this machine uses a small-port inlet design that first presses the plunger and then fills the syringe, preventing air entrapment and ensuring accurate shot volumes. The HMI interface allows for quick recipe adjustments to suit varying product viscosities, while multiple pump options provide the flexibility needed for different physical properties.
How It Works & Operational Benefits
1.Material Handling: The machine accepts a standard 20L pail. The press plate descends to push the high-viscosity material toward the pump intake.
2.Positive Displacement: The servo-driven metering pump provides precise volumetric control, independent of pressure fluctuations.
3.Drip-Free Dispensing: The suction-back valve provides clean cut-off, maintaining a neat working environment and saving valuable materials.
Operational Advantages:
1.Bubble-Free Filling: The small inlet ensures that the material fills the syringe from the bottom up, pushing air out.
2.Low Maintenance: The robust pump design and stainless-steel construction make cleaning and parts replacement straightforward.
3.Flexible Consumables: Supports various syringe sizes and injectors, making it perfect for both R&D pilot runs and mass production lines.
