Automatic PP/PU Filter Gluing & Dispensing Machine

This high-performance Automatic Filter Gluing and Dispensing Machine is engineered to deliver high-precision polyurethane (PU) foam gasket casting and adhesive sealing for industrial filter elements. By integrating automated material dispensing with a stable pneumatic system, it provides consistent gluing quality on air filter frames, automotive cabin filter edges, and heavy-duty dust collector end caps.

The automated system utilizes a dual-component mixing head and precise mechanical controls to apply adhesives or sealants without waste, ensuring that finished filters meet strict leakage and air-tightness B2B standards. It is the perfect choice for scaled factories seeking consistent potting quality and minimized labor requirements.

Technical Specifications

To ensure the machine matches your factory’s electrical and technical requirements, the standard parameters of this dispensing system are detailed below:

Key Features & Mechanical Advantages

1. High-Precision PU Dispensing Valve

The machine features an advanced high-precision glue dispensing valve that ensures even foam flow, preventing gaps, bubbles, or overflow. This consistent bead application guarantees a leak-proof seal between the filter media and the frame.

2. Digital Flow Rate & Ratio Adjustment

Operators can easily adjust the glue mixing ratio, flow rate, dispensing speed, and path configurations directly via the touchscreen control panel. This digital setup enables quick recipe recall and significantly reduces changeover times for different filter sizes.

3. Integrated Automatic Cleansing System

To prevent adhesive curing and clogging within the dispensing head, the machine is designed with an automatic flushing and air-purge cleaning cycle, ensuring hassle-free startup and minimizing daily maintenance.

4. Rigid and Vibration-Free Steel Frame

Built with high-rigidity structural steel, the machine maintains outstanding mechanical stability during high-speed XYZ-axis movements. This stable physical foundation prevents positioning drift, ensuring micro-level repeatability.

Applications & Industrial Uses

This automated filter gluing and dispensing system is widely deployed in production lines manufacturing:

• Automotive Engine Filters: Sealing polyurethane borders on standard panel engine air filters.
• Car Cabin HVAC Filters: Applying hot-melt or PU glue lines along the side panels of air conditioning filters.
• HEPA Air Purifier Filters: Potting high-efficiency particulate air filters into plastic or metal frames.
• Industrial Dust Collectors: Dispensing elastic PU gaskets onto heavy-duty metal or plastic end caps.
