Filter Manufacturing

Nordson dispensing systems help filter manufacturers improve productivity in bonding, sealing and gasketing filter media using polyamides, plastisols, urethanes, silicones and other high-performance materials. Systems are also available for efficient media lamination.

• Eliminate labor-intensive manual application of die-cut or foam-tape gaskets using Ultra FoamMix® and FoamMelt® systems to produce automated foam-in-place gaskets.

• Reduce adhesive material costs by applying foamed beads for filter pleating and heavy-duty radial filters using the Ultra FoamMix, SureFoam™ or FoamMelt systems.
  
  
• Improve substrate coverage in applying plastisols to oil filter end caps using AG-900 guns equipped with a showerhead nozzle.
  
  
• Achieve reliable dispensing in disposable HVAC air filter assembly with Blue Series™  melters and Universal™ CF®  nozzles, slot or bead guns.
  
  
• Improve bonding and preserve material properties of high-temperature hot melt and polyamide adhesives using EX series hot melt extruders that provide a graduated melting process.
  
  
• Use Ultra FoamMix applicators to create a homogenous, closed-cell foam offering performance and production benefits over conventional hot melt adhesive dispensing.
  
  
• Improve laminating efficiency with clog-resistant Universal Signature™ spray nozzles that dispense dense, random patterns in continuous coating applications.
