The electrostatic powder coating
machine model RSC of Hamburg,
Germany-based Rolf Schlicht GmbH
was designed for an even, finely
dosable and absolutely dust free
powdering of cables, wires, hoses and
profiles with powders like talc,
stearate, lac powder, swellable
powder, etc.
By the electrostatic charging of the
powder a strong adhesive and even
layer on the surface is reached. The
electrostatic also makes sure that no
powder falls from the product outside
of the dusting chamber. Depending on
extrusion speed and product diameter,
one to four powder guns of 100kV
each are used.
In the machine there is a fluidised
powder hopper out of which the
powder is sucked by pneumatic
venturi pumps and blown to the guns.
For an optimal adjustment of the
powder quantity the operator can
adjust the power of the electrostatic
charging from 0-100kV, the powder
quantity and the speed of the dust
cloud. Depending on the product the
powder gun can be equipped with
different powder nozzles.
In the machine there is a fully
automatic and maintenance-free filter
system that is cleaned off by a special
process. Thanks to this filter system a
strong and constant vacuum is
generated in the machine,
guaranteeing no escape of the powder.
If there is not enough space in the line
to place the machine Schlicht can
deliver a free-standing dusting
chamber which is connected to the
machine by hoses.
For an extremely fine powdering of
slowly running products Schlicht offers
a fine dosing device to make sure that
only a minimal amount of powder is
transported to the guns.
