Industrial automatic filter end cap gluing machine designed for precise PU and resin glue injection on filter element end caps. Features a 40–250 mm gluing diameter, 5–20 g/s adjustable glue flow rate, and a high-precision servo motor screw pump system. For specialized conical and oval air filter end cap potting, please view our [Automatic Cone Air Filter Gluing & Dispensing Machine](/cone-air-filter-glue-machine).
This industrial-grade Automatic Filter End Cap Gluing Machine is specifically engineered for high-precision adhesive potting and dispensing on various filter element end caps, including diesel fuel filter cartridges, heavy-duty engine cartridges, and industrial dust filters.
Compatible with both polyurethane (PU) foams and epoxy resin adhesives, this versatile system ensures a perfectly even, consistent adhesive layer on every end cap. Driven by an advanced servo motor screw pump and equipped with an anti-clogging pneumatic nozzle, it is built to maximize production efficiency, minimize adhesive waste, and eliminate common sealing leaks in filter assembly.

Key Features & Mechanical Advantages
1. High-Precision Servo Motor Screw Pump
The adhesive delivery system is powered by a high-torque servo-driven screw pump. This system ensures micro-accurate volumetric metering, maintaining strict weight tolerances on each end cap and ensuring consistent bonding quality across all filter batches.
2. Pneumatic Anti-Clogging Dispensing Nozzle
The machine features a small-dosage pneumatic nozzle engineered with a built-in anti-clogging mechanism. This design prevents chemical crystallization, ensures a smooth, uninterrupted adhesive flow, and drastically reduces daily manual maintenance.
3. Ergonomic Pneumatic Lifting Mechanism
Equipped with a sturdy pneumatic lifting cylinder, the system enables fast, safe, and comfortable workpiece handling. This pneumatic assist streamlines filter element loading and unloading, reducing worker fatigue during long manufacturing shifts.
4. Built-In Automatic Air-Purge Cleaning
To prevent mixed dual-component chemicals from curing inside the dispensing head, the machine incorporates an automatic air-purge sequence. This automated flush quickly clears the nozzle at the end of each cycle, minimizing maintenance downtime.
5. Sturdy and Stable Frame Construction
Constructed upon a heavy steel alloy chassis with a total power rating of 5 kW, the machine absorbs mechanical movement smoothly, preventing positioning drift and guaranteeing repeatable potting accuracy.
