The adhesive
or
thermoplastic material dispensed by the hot melt
system.
The applicator, hose(s), gun(s) and timing mechanism.
A system that regulates flow rate in proportion to the substrate (line)
speed.
A device that shows
the level of material in
a
tank, reservoir or hopper.
A device that converts applied voltage to
light.
LEDs
appear as colored
lights that indicate operating conditions.
See Level lndicator.
The device that distributes fluid and/or
air.
The highest cycle rate
of
the gun that produces a repeatable pattern.
The maximum adhesive flow rate achievable without exceeding any
operating
limits. The
maximum
pumping rate is measured
at
the
manifold
outlet. The
rate is based on an adhesive with a given viscosity.
The rate at which a materialcan be melted continuously on a long-term
basis
while maintaining the output fluid temperature within a desired
temperature band.
Commonly
expressed in units of grams/minute,
grams/hour, lb/min
or
lb/hr.
The extrusion tip, the point at which the adhesive exits the
gun.
The
nozzle controls the adhesive stream's volume, shape and direction.
Nozzles may have single or multiple orifices.
The
time after adhesive is applied during which
a
seruiceable bond can
be
made.
Many factors affect open time, including temperature,
substrate, the
adhesive used and the amount of adhesive applied.
The pressure at which the pump and/or guns are
operated. See product
specifications.
The range
of temperatures in which the specific material or adhesive
in
use
functions satisfactorily in a particular application.
A product feature that shuts down the unit or produces an alarm when
temperatures are outside
a
specified band.
