EX Extruder Systems
Description
A Nordson extruder is the first choice when processing “difficult” adhesives like polyamides, polyester, or
polyolefin (APAO). These adhesives ask for a closed system to avoid degradation of the adhesive through
carbonization and consequently loss of bonding performance or other problems within the system.
Extruders enable homogeneous melting in a fully closed “melt-on-demand” system to provide a safe and reliable
application process.
Nordson extruders offer the fastest, easiest adhesive changes possible compared to other melters without timeand
cost-intensive cleaning procedures.
Convincing advantages at a glance:
• Optimized for adhesive applications
• A true “melt-on-demand” system, deliver the lowest
possible thermal stress on the adhesive
• No degrading or charring at all because it is a fully
closed system
• A self-cleaning system
• Virtually maintenance free system
• Option to change adhesives during production within a
few minutes
• Short heat-up times
• Lower energy consumption per kilogram compared to
conventional tank melters
• Results in more economical operating costs of the
complete application system
EX extruder systems are for use in applications requiring the highest precision and performance with regard
to temperatures and pressures. EX extruders are designated Engineered Systems, which are engineered to the
specific requirements of our customers, offering the highest flexibility and grade of customization for a perfectly
suited system.
