Product Description

Product Description

Plunger Dispensing Valve:

    Discover the epitome of precision with our Plunger Dispensing Valve, a state-of-the-art plunger-type dispensing head meticulously engineered to control adhesive outputs through dynamic plunger movements. Equipped with an innovative back-suction function, this valve ensures seamless and continuous dispensing, making it the ultimate choice for applications demanding rapid, efficient handling of high-viscosity and high-liquid materials. From coating fillers to grinding media, and including single-component and two-component casting resins, this valve excels, managing viscosities from 10,000 to 100,000 with ease.
    Rooted in the volumetric dispensing principle, the plunger dispensing valve's functionality is defined by the precise geometry of its cylinder and stroke. This ensures that dispensing volume remains unaffected by external variables like temperature, feed pressure, or material viscosity. With a steadfast mixing ratio for two-component media, it guarantees stability within a versatile range of 1:1 to 10:1, promising consistent performance across diverse applications.

Advantages:
1. Experience fast and effortless maintenance
2. Benefit from an extended service life, ensuring cost-effectiveness
3. Enjoy significantly reduced service expenses
4. Customize with optional features such as valve monitoring, mixing tube heating, and dispenser heating
5. Achieve unmatched adaptability to meet any requirement

To enhance production efficiency, we have developed both 2 and 4 needle modules, perfectly suited for simple dispensing tasks and smaller products. This innovation not only maintains precision but also enables the completion of multiple products simultaneously, revolutionizing your production process.

Specification

    Volumetric piston dispensers stand as the pinnacle for dispensing both very liquid and highly viscous materials with remarkable ease. Whether dealing with filled, abrasive media, or 1K and 2K casting resins, these dispensers excel, making them the preferred choice for a range of applications including filling, sealing, and adhesive bonding, as well as applying thermally conductive pastes. Our piston dispensers operate on the volumetric dispensing principle, where material quantity is determined by cylinder geometry and stroke, ensuring independence from temperature, feed pressure, or material viscosity. When utilizing 2C media, a consistent mixing ratio is maintained within a 1:1 to 100:10 range, achieved by the simultaneous discharge of both cylinders into a shared mixing tube.

Typical Applications:

- SMT solder paste or adhesive dispensing

- LED module assembly

- FPC bonding

- Medical device manufacturing
