Particular features

■ Screen coating thicknesses vary from one print job to another. Until recently, screens of varying thicknesses could be achieved only by using expensive capillary films. Also, modern exposure systems demand very thin and evenly coated screens which, by normal coating processes, 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 G-COAT 401 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 available:

Base profile

■ The max. length of the base profile made of anodized aluminium is 7100 mm / 280”.

Dust protection cover

■ The standard version of all the coating troughs with a max. length of 2000 mm / 79” includes a hinge-type dust protection cover TOP-COVER.

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.

Type 1: Coating edge with 2 radii

r = 0,25 / 0,75 mm

Type 2: Coating edge with 2 radii

r = 0,50 / 1,00 mm

■ The max. length of the coating edges made of anodized aluminium is 7100 mm / 280”.

■ If spare coating edges are ordered together with the G-401 trough, they can be replaced at a later date.

When ordering, please specify the maximum trough width;
The reference values are the following:
Screen frame size up to 2060 mm / 81”
Inner frame size - 60 mm / 2,4” = red trough (squeegee side RS)
Inner frame size - 85 mm / 3,3” = black trough (print side DS)
Screen frame size up to 7100 mm / 280”
Inner frame size - 100 mm / 4” = red trough (squeegee side RS)
Inner frame size - 150 mm / 6” = black trough (print side DS)
