Choosing the Right Glue Supply Module: A Complete Guide to Plunger Assemblies, Dispensing Pumps, and Two-Component Screw Valves
In modern manufacturing processes, especially in electronics, automotive, and new energy industries, precision dispensing systems play a critical role in ensuring product quality and production efficiency. At the heart of every dispensing system lies the glue supply module, which directly affects flow stability, glue control, and material compatibility.
This article explores the core types of glue supply modules — Plunger Assemblies, Barrel Dispensing Pumps, and Two-Component Screw Valves — helping engineers and purchasing managers choose the right component for their specific process needs.
1.Plunger Assembly: Compact, Stable, and Ideal for 50ml Cartridges
The 50ml Servo Plunger Assembly is designed for small to medium-volume applications. Its cage-type structure provides excellent stability and resistance to deformation under pressure. Key features include:
*Guided push-rod design for consistent plunger movement
* Compatible with 50ml 1:1, 2:1, 4:1, 10:1 glue cartridges
* Supports a wide viscosity range (10,000 – 500,000 CPS)
* Equipped with a switchable suck-back valve to improve start-stop dispensing precision
* Optional cooling module to slow chemical reactions and extend pot life
* Can be integrated with a dedicated intelligent glue controller for visible, stable parameters
✅ Recommended for users seeking a cost-effective, compact glue supply solution for precise manual or semi-automatic applications.*
2.Dispensing Pump Module: High-Volume, High-Viscosity Powerhouse
The 5-Gallon Servo Screw Dispensing Pump is built for high-throughput environments. Featuring a dual-barrel system with servo-driven screw pumps, it offers pulse-free and continuous dispensing of high-viscosity materials.
Key highlights:
* Viscosity range: Supports 10,000 – 1,000,000 CPS
* Material compatibility: Silicone, epoxy, polyurethane, UV glue, grease, conductive paste, solder paste, and more
* Real-time flow rate and volume adjustment via dedicated controller
* Supports continuous operation with dual cartridges (non-stop refilling)
* Ideal for 5-gallon pail packaging
✅Best suited for automated lines requiring stable, uninterrupted, high-viscosity material delivery.
3.Two-Component Screw Valve: Precise Mixing for A/B Ratio Materials
For dual-component adhesives, the Two-Component Screw Valve offers a high-precision mixing and dispensing solution. It ensures consistent ratio control and reliable blending for a wide range of adhesives and reactive resins.
* Suitable for 100 – 15,000 CPS viscosity materials
* Compatible with RTV, anaerobic glue, epoxy, polyurethane, and more
* Delivers accurate volumetric output and homogeneous mixing
* Ideal for A/B component control in electronic potting, sealing, and conformal coating processes
✅ Perfect for precision dosing and reactive adhesive applications where ratio accuracy is critical.
Final Thoughts: Matching Modules to Materials
Choosing the right glue supply module depends on three key factors:
* Material viscosity
* Packaging size (e.g., 50ml, 5-gallon)
* Application type (manual, semi-auto, inline automation)
