Product Description

Product Description

Screw Dispensing Valve:

Discover the innovative Screw Dispensing Valve, designed as a metering dispensing head that excels in the handling of hot melt and thermal conductive adhesives with medium to high viscosity. This versatile solution offers exceptional flexibility, allowing for precise adjustments to glue volume and coating across diverse workpieces. At the heart of its operation are the rotor and stator, which create a perfectly sealed metering chamber, ensuring consistent dispensing unaffected by fluid viscosity. Enhance your operations with optional high-flow, micro, and dual-liquid screw dispensing valves tailored to your specific needs.

Experience the precision of our screw dispenser, which utilizes screw rotation for both suction and dispensing, enabling the application of fine dots and lines. This volumetric metering screw pump operates seamlessly regardless of liquid viscosity, thanks to its endless piston mechanism, allowing for uninterrupted dispensing.

Dispensing Needle: 
Our dispensing needles are crafted to cater to diverse requirements, accommodating both single-component adhesives and dual-component glues (AB adhesives) with ease.
