G-COAT 401
Coating trough MODULAR Pat. no.0794461
Particular characteristics
■ The requirements to be answered by modern
printing forms are getting more stringent by the
day. Until recently, high-quality printing screens
could only be achieved by using expensive capillary films. Also, state-of-the-art exposure systems
demand a highly uniform coat thickness without
which an efficient production would be impossible.
■ For the above-mentioned reasons, and based on
our many years of experience in the field of coating technology, we have developed the completely new G-COAT 401 trough generation.
■ The coating troughs can be used not only as
manual coating troughs but also on all Grünig
automatic coating machines.
■ The concept is based on a modular system made
up of several individual elements which can be
combined according to the respective requirements and applications.
The following individual components are
Base profile
■ The max. length of the base profile made of anodized aluminium is 7100 mm.
Coating edge
■ You have the free choice of several MULTI-RADIUS aluminium coating edges (the available radii
are 0,25/0,50/0,75 and 1,00mm) which allow easy
confectioning as they can simply be pushed onto
the base profile. This precise radius gradation
allows an extremely precise control of the coating
layer build-up, while at the same time reducing the
coating time and allowing to realize any required
copying layer. The quality with regard to the
tolerances of the layer thickness and the surface
roughness can thus be controlled with great precision, which enables the user not only to reduce
his manufacturing costs but also to guarantee an
efficient manufacturing process.

■ The max. length of the coating edges made of
anodized aluminium is 7100 mm.
■ If spare coating edges are ordered together with
the G-401 trough, they can be replaced at a later
Dust protection cover
■ The standard version of all the coating troughs
with a max. length of 2000 mm includes a hingetype dust protection cover TOP-COVER.
