gently in an axial direction. Progressive
cavity pumps are therefore highly
suitable for processing filled and
abrasive materials.
Rotordis and rotormix are each
available in four different nominal sizes:
0.01, 0.05, 0.15 and 0.30 ml/U. Rotordis
enables shot sizes from 0.002 ml (2 μl)
to be processed at a discharge rate of
0.13-45 ml/min, while rotormix enables
shot sizes from 0.006 ml (6 μl) to be
processed at a discharge rate of 0.26-90
ml/min. In both cases, this is dependent
on the viscosity and, in the case of
rotormix, also on the mixing ratio.
Metering precision is ± 1 per cent.
With rotordis and rotormix, materials
with different viscosities can be
CONTINUOUS METERING AND MIXING ADHESIVES
AND SEALANTS
DOPAG has added progressive cavity pump systems for 1K and 2K materials to its
product range
.
When processing adhesives and sealants, as well as epoxy resin and silicone,
continuous metering is necessary for certain applications. Metering systems
with progressive cavity pumps are suitable for this as they work based on the
volumetric metering principle, meaning they enable highly precise metering of the
material quantity.
DOPAG offers two metering systems with progressive cavity pumps:
* rotordis for processing single-component materials
* rotormix for metering and mixing multi-component materials
Progressive cavity pumps work with no pulsation. Consisting of two
components, the stator-rotor combination is the heart of the progressive cavity
pump. This is a volumetric metering system that is sealed leak-free. It conveys
the material continuously without any restrictions on volume, with low shear and
processed, ranging from
water-thin to highly viscous or pasty.
Depending on the viscosity, cartridges,
pressure tanks or barrel pumps can be
used. With both systems, application is
generally carried out directly from the
metering system onto the component
by means of a nozzle or mixing tube.
A DC drive enables dynamic metering
and a controllable back suction effect.
This ensures a clean thread break at all
times.
A specially developed electronic
metering control unit ensures optimal
adaptation of all application-specific
parameters. In addition, straightforward
integration into automated production
processes is ensured thanks to a
standardized interface.

AC AND DC MEASUREMENT
SOLUTION
Lambient Technologies LLC, a developer of precision
measurement solutions for the curing of advanced
composites, has released the LT-440 Dielectric
Channel, which it claims is the first composites
cure measurement solution to combine AC and
DC measurement capabilities. By adding DC to its
longstanding AC measurement capabilities, Lambient
can now provide accurate data on the cure of extremely
resistive materials, such as silicones.
For users who currently rely on alternative DC
measurement solutions, the LT-440 provides the
added toolset of AC measurement. This allows users
to measure cure in applications deploying barriers
like vacuum bags and release films, where DC
measurements won't work. DC users also gain the
ability to use AC measurements to more accurately
follow the entire cure.
