Automatic PU Glue Dispensing Machine for Filter End Cap Potting and Bonding
The Filter End Cap Glue Machine is designed for accurate adhesive dispensing, polyurethane (PU) potting, and bonding applications in filter manufacturing. It provides controlled glue application between filter media and end caps to support reliable bonding, effective sealing, and consistent product quality. Suitable for automotive filters, air purifier filters, HVAC filters, and industrial filter cartridges, the system can be configured for one-component or two-component adhesive materials according to production requirements. Optional automatic dispensing control, customized fixtures, rotary tables, and conveyor integration help improve production efficiency and reduce material waste. With flexible dispensing parameters and application-specific configurations, this filter end cap gluing solution can be adapted to different filter sizes, end cap geometries, adhesive properties, and manufacturing processes.
The Two Part PU Dosing Machine for Filter End Cap is designed for accurate metering, mixing, and dispensing of two-component polyurethane (PU) materials in filter manufacturing. It delivers Components A and B according to a preset mixing ratio and dispenses the mixed material into filter end caps to support bonding, sealing, and encapsulation.
Featuring a precision metering system, a mixing unit, and a controlled dispensing valve, this polyurethane dosing solution helps improve dispensing consistency, reduce material waste, and support efficient production. The system can be customized for different filter sizes, end cap designs, PU material properties, and production requirements.
Suitable for air filters, automotive filters, industrial filter cartridges, and other filter assemblies, the equipment can be integrated with fixtures, rotary tables, or conveyor systems to meet different levels of automation.

Working Principle
- PU Material Storage: Components A and B are stored separately to prevent premature reaction.
- Material Conditioning: The materials are prepared according to the required viscosity and processing conditions. Optional heating, stirring, or pressure regulation may be used.
- Precision Metering: Independent pumps deliver the two PU components at the preset mixing ratio.
- Component Mixing: The materials enter a static or dynamic mixing unit to achieve the required mixing uniformity.
- Filter End Cap Dosing: The mixed PU material is dispensed into the end cap or designated bonding area through a dispensing valve.
- Curing and Assembly: The filled filter components proceed through the required curing process before subsequent assembly or inspection.
- Automated Cycle Control: The control system coordinates dispensing volume, valve operation, and workpiece positioning for repeatable production.
