The plunger dispensing valve is a plunger-type dispensing head that controls the output of adhesive by the movement of the plunger. It has a back-suction function, facilitating continuous dispensing. It is an ideal choice for rapid 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, with a viscosity range of 10,000 to 100,000.
The plunger dispensing valve is based on the volumetric dispensing principle. The dispensing volume is determined by the geometry of the cylinder and the stroke. The dispensing ratio is not dependent on temperature, feed pressure, or material viscosity. The mixing ratio of two-component media can be guaranteed to be stable, with an applicable ratio range of 1:1 to 10:1.
Advantages:
1. fast and easy maintenance
2. long service life, Cost-effective
3. significantly reduced servicing costs
4. optional features such as valve monitoring, mixing tube heating and dispenser heating
5. the system can be adapted flexibly to any requirement
Appliable process: heat dissipation, potting, sealing, bonding, etc.
Appliable material: single-component, two-component, fluid or high viscosity materials, with / without fillers, highly abrasive materials.
Applications material: highly liquid adhesives, sealants and castings, highly viscous and/or filled materials.
In order to improve the production, we designed 2 and 4 needles module which suitable for simple dispensing and small product, thus not only keep the precision, also can finish more products one time. Other advantages:
1. High-precision control: enable ultra-precise regulation of adhesive flow and dispensing volume, ideal for applications demanding micron-level accuracy.
2. Material versatility: compatible with adhesives across a wide range of viscosities (low to high) and chemical compositions.
3. Anti-drip retraction function: built-in retraction mechanism instantly withdraws adhesive after dispensing, eliminating drips, reducing waste, and ensuring clean dispensing patterns.
4. Easy to clean and maintain, convenient to change different types of adhesives.
5. Robust durability: constructed with wear-resistant materials for extended lifespan, even in harsh industrial environments.
6. Adjustable process parameters: speed, pressure, and dispensing cycle can be finely tuned to meet diverse production requirements
7. Flexible operation: supports manual operation or integration into fully automated production systems.
8. Cost-effective production: lower initial investment and maintenance costs compared to pneumatic or rotary valve systems, with higher efficiency in high-volume manufacturing.

In order to meet the requirements for the use of other typs of adhesives, we designed other dispensing valves: screw dispensing valve, gear pump dispensing valve.
Screw Dispensing Valve:
The screw dispensing valve is a screw valve metering dispensing head, which is mainly used for metering hot melt adhesives and thermal condustive adhesives with medium and high viscosity, providing high flexibility for variable glue volume and glue coating on different workpieces. Its core components, the rotor and stator, form a completely sealed metering chamber to achieve continuous metering dispensing, which is not affected by fluid viscosity. Optional high-flow screw dispensing valves, micro screw dispensing valves, and dual-liquid screw dispensing valves.
Gear Pump Dispenser:
Gear pump dispensing valve is a gear-driven metering dispensing head utilizes a gear pump mechanism to precisely control adhesive output, making it an optimal solution for high-speed continuous dispensing and variable-volume applications. The dispensing volume is determined by gear geometry, number of teeth, and rotational speed. This system ensures continuous, stable material flow, and excels at rapidly and accurately handling geometrically complex workpieces with intricate 2D/3D contours.
