Fluid-bed plant

with powder coating

RUD Ketten Rieger & Dietz GmbH & Co. KG installed a new, fully automatic coating plant as part of a capacity expansion. This plant enables coating with fluid-bed and electrostatic powder coating processes.

As a manufacturer of high-quality, powder-coated outdoor furniture and sanitary furnishings made of steel and aluminium, RUD has been able to gain many years’ experience with the aforementioned processes on an existing plant.

The plant product range is comprised of 3 possible coating variants:

  1. Fluid-bed
  2. Fluid-bed + electrostatic coating
  3. Electrostatic coating

There are already 5 colours (white, pine green, anthracite grey, dark grey, white aluminium) made from polyamide 11 available for the fluid-bed coating. Given a suitable order volume, other colours, e.g. powder coating such as polyester, can also be used. Coating thicknesses of between 300 µm and 800 µm are possible.

Moreover, there is the option of coating the fluid-bed internal parts with electrostatic powder coatings of any type and colour (with the exception of acrylics).

As a third variant, parts up to 3.20 m can be coated with undercoatings and top coatings made from electrostatic powder coating material.

The coating processes mentioned above can be applied to parts with the following maximum dimensions:

LengthWidthHeight
Fluid-bed2,50 m0,80 m1,50 m
Fluid-bed + electrostatic coating2,50 m0,80 m1,50 m
Electrostatic coating3,20 m0,80 m1,50 m

Blasting plants with edged, hardened and stainless steel are available for pretreatment purposes.
