EEX Extruder System
Extruder simplifies
safe, high-quality
processing of hot
melt adhesive
granules.

Nordson extruders provide precise, homogenous melting of
adhesive granules. As only the material immediately needed
is processed, production is virtually maintenance free and
crosslinking of adhesive is nearly impossible. Additionally,
switching adhesives does not require cleaning the extruder.

+ Maintenance-free three-phase AC motors with frequency
converter.

High Quality and Safety

Features and Benefits

+ Protection against running dry with safety cutoff in case
of interrupted granule feed.

+ Microprocessor-controlled, multi-circuit temperature
control including delayed warm-up phase for all
temperature control circuits.

+ Soft start-up to avoid pressure peaks.
+ Water cooled draw-in area prevents clogging of granules
and backwash of liquid material.
+ Hardened nitride steel cylinder and worm.
+ Pressure control for feeding flanged pump station coating
heads.

+ Safety pressure switch at each pump exit.
+ Automatic control for pumps and dosing heads.

+ Error diagnostic program for all temperature circles.
+ Start-up circuit with monitoring of temperature drops and
temperature increases for all heating zones.
+ Cylinder and worm manufactured of nitride steel,
hardened.

Flange-mounted Pump Station

+ Water cooled draw-in area for connection to cooling water
circulation or external cooling system (optional).

+ Volumetric dosing with up to four separately controlled
gear pumps.

+ Equipped with gear pump station with continuously
adjustable gear pumps with AC drive (optional).
