Product Description

Product Description

Plunger Dispensing Valve

    The plunger dispensing valve is an ingeniously designed plunger-type dispensing head that meticulously controls adhesive output through the dynamic movement of the plunger. Featuring an advanced back-suction function, it ensures seamless and uninterrupted dispensing. This makes it the quintessential choice for the swift dispensing of high-viscosity and high-liquid materials, such as coating fillers or grinding media, as well as single-component and two-component casting resins, boasting an impressive viscosity range of 10,000 to 100,000.
    Our plunger dispensing valve operates on the reliable volumetric dispensing principle. The volume dispensed is precisely determined by the cylinder's geometry and the plunger stroke, ensuring the dispensing ratio remains unaffected by temperature, feed pressure, or material viscosity. Enjoy peace of mind with a stable mixing ratio for two-component media, applicable within an expansive ratio range of 1:1 to 10:1.

Advantages:
1. Experience fast and effortless maintenance.
2. Benefit from long-lasting service life and cost-effectiveness.
3. Enjoy significantly reduced servicing costs.
4. Access optional features like valve monitoring, mixing tube heating, and dispenser heating for enhanced performance.
5. The system offers the flexibility to adapt to any requirement seamlessly.

Typical Applications:

- SMT solder paste or adhesive dispensing

- LED module assembly

- FPC bonding

- Medical device manufacturing

To boost production efficiency, we have ingeniously designed 2 and 4 needle modules that cater to simple dispensing and small products, maintaining precision while enabling the simultaneous completion of multiple products.

Specification

Volumetric piston dispensers are the epitome of versatility, perfectly suited for both extremely liquid and highly viscous materials. Effortlessly apply filled and/or abrasive media, as well as 1K and 2K casting resins. This adaptability makes them ideal for applications such as filling, sealing, adhesive bonding, and even applying thermally conductive pastes. Our piston dispensers adhere to the volumetric dispensing principle, with material quantity precisely governed by the geometry and stroke of the cylinders. As this process is mechanically determined, the dispenser operates independently of temperature, feed pressure, or material viscosity. When using 2C media, enjoy a consistent mixing ratio, maintained within a range of 1:1 to 100:10, by simultaneously discharging both cylinders into a shared mixing tube.
