What type of dispensing valve should be used for epoxy resin glue?

Epoxy resin adhesives are widely used in electronics manufacturing, LED packaging, automotive electronics, and other industries due to their excellent performance. However, the high viscosity of this adhesive presents special requirements for dispensing processes. As a professional fluid control solutions provider in Shenzhen, Leica Technology, with years of industry experience, provides a detailed introduction to the key points of epoxy resin adhesive dispensing valve selection.

Characteristics of Epoxy Resin Adhesives and Dispensing Requirements:

Epoxy resin adhesives have high viscosity and easy curing characteristics, which pose special requirements for dispensing equipment: a strong driving force is needed to cope with high viscosity, precise flow control is required, good sealing performance is needed to prevent adhesive curing, and wear-resistant design is needed to cope with possible fillers.

Leica Technology's Recommended Dispensing Valve Solutions:

1. Screw Dispensing Valve

Especially suitable for high-viscosity epoxy resin adhesives and AB adhesives: It adopts a unique rotating propulsion principle, has low shear force on the adhesive, stable and reliable flow output, and a patented sealing structure effectively prevents adhesive curing and blockage. Typical application scenarios include electronic component packaging, etc.

2. Pneumatic Plunger Dispensing Valve

Suitable for medium-viscosity single-component epoxy resins: The high-precision drive system ensures consistent dispensing, the modular design facilitates daily maintenance, and an optional heating function improves adhesive fluidity. It is commonly used in circuit board component fixing and other processes.

3. Precision Jet Valve

An ideal choice for low-viscosity, fast-drying epoxy adhesives: It adopts advanced drive technology, has a fast response speed, non-contact dispensing avoids drawing problems, and can achieve a tiny dispensing amount, especially suitable for precision electronic assembly applications.
