Extruders are commonly used for applications where polyamide
or polyester based adhesives are processed. These adhesives
need a closed system to avoid degradation of the adhesive
through carbonization and to provide a safe, reliable application
process.
Nordson extruders offer the fastest, easiest adhesive changes
possible without time- and cost-intensive cleaning procedures.

EX extruder systems can also be equipped with Nordson´s Ultra
FoamMix® unit. The Ultra FoamMix process offers dramatic
reduction of adhesive consumption, up to 50%, while maintaining
or improving the bonding performance of the adhesive. Please
refer to separate Ultra FoamMix documentation for additional
information.
Nordson EX extruder systems can be customized to specific
application requirements up to full integration into production
lines. The system can be equipped with various standard fieldbus
communication interfaces.
