VeriTec VT44 Series Adhesive
Dispensing Electric Guns
Cold adhesive electric guns
combine rapid cycle speeds
and multi-module flexibility
for dispensing complex
patterns in high-speed
non-contact applications.
Nordson’s VeriTec™ brand VT44 Series electric guns
feature compact size and multi-module capability for
precise delivery of cold adhesive extrusion dots. These
guns are ideal for high-speed non-contact converting
applications that require consistent placement of
complex patterns at exceptionally high cycle rates.
VT44 Series guns offer cycle rates as high as 800 cycles
per second with a duration as low as 4 milliseconds.
This capability equates to dot placement at 2-millimeter
distances for production speeds up to 96 meters per
minute (314 ft/min). VT44 guns accurately dispense cold
adhesives with viscosities up to 1000 centipoise when
used with a Nordson diaphragm pump or WM360 high-performance
piston pump. Consistent adhesive delivery of a broad viscosity
range allows manufacturers to handle a wide variety of substrates
and bonding requirements.
A ball-plunger and cone assembly provides clean adhesive
cut-off of high viscosity adhesives. This design provides reliable
adhesive flow control and permits flexible gun mounting at
distances 6 to 10 millimeters away from the substrate.
Efficient design permits complex
patterns and dependable performance
in high-volume production.
s Selection of designs is available in single or multiple
groupings of 4, 6, 8, 12 and 16 modules on a single manifold
with close centerlines of 14 mm (0.55 in.).
s All-electric operation and wide viscosity range satisfy
diverse application requirements for high-speed extrusion
dot patterns.
s Multiple gun configurations allow complex pattern
arrangements to satisfy exacting requirements.
s Automatic tip sealer prevents adhesive skinning over the
nozzle during dwell times.
s Clean adhesive cut-off minimizes adhesive tailing to
improve bonding quality and reduce rejects.
s Compact size and choice of mounting profiles allow
double rows of gun manifolds from a common glue feed to
meet specific pattern arrangements.
s Optional front or top hydraulic porting accommodates
specific mounting constraints.
s Corrosion-resistant and stainless steel parts provide
durability and help prolong gun life.
s Custom-designed bracketry adapts to each parent
machine’s unique mounting requirements.
