Product Description

Product Description

Plunger Dispensing Valve

    The plunger dispensing valve is a sophisticated, plunger-type dispensing head that masterfully controls adhesive output through the adept movement of the plunger. With its innovative back-suction feature, it enables seamless continuous dispensing. This valve is unparalleled for swift dispensing of high-viscosity and dense liquid materials, including coating fillers and grinding media. It's equally adept with single-component and two-component casting resins, efficiently handling viscosities from 10,000 to 100,000 with precision.
    The plunger dispensing valve operates on a precise volumetric dispensing principle. The dispensing volume is meticulously determined by the cylinder's geometry and the precise stroke. Remarkably, the dispensing ratio remains unaffected by temperature fluctuations, feed pressure variations, or material viscosity changes. This ensures a stable mixing ratio for two-component media within an applicable range of 1:1 to 10:1, guaranteeing consistent results.

Advantages:
1. Fast and easy maintenance ensures minimal downtime.
2. Long service life, offering exceptional value and cost-effectiveness.
3. Significantly reduced servicing costs, enhancing overall efficiency.
4. Optional features available, including advanced valve monitoring, mixing tube heating, and dispenser heating for enhanced performance.
5. The system boasts remarkable flexibility, adapting seamlessly to any specific requirement.

Typical Applications:

 - SMT solder paste or adhesive dispensing

 - LED module assembly

 - FPC bonding

 - Medical device manufacturing

To revolutionize production, we've ingeniously designed 2 and 4 needle modules, perfectly suited for simple dispensing and small-scale products. This innovation not only ensures precision but also enables the completion of multiple products simultaneously, boosting efficiency.

Specification

    Volumetric piston dispensers excel in handling both very liquid and highly viscous materials with ease. They seamlessly apply filled and/or abrasive media, as well as 1K and 2K casting resins, making them indispensable for filling, sealing, and adhesive bonding applications. Perfect for applying thermally conductive pastes, these dispensers rely on the volumetric dispensing principle. The material quantity is determined by the geometry and stroke of the associated cylinders, ensuring independence from temperature, feed pressure, or material viscosity. When using 2C media, the mixing ratio remains constant, within a range of 1:1 to 100:10, by simultaneously discharging both cylinders into the shared mixing tube.
