Precise powder enamel application with a robot has many benefits, such as :
– lowest specific enamel consumption
– strongly reduced over-spray
– small factory footprint

As reported during the 24th International Enamellers congress in Chicago last May, vitreous enamel frit manufacturers, particularly in Europe, are working to reduce or eliminate the use of metals like cobalt and nickel as well as the use of boron compounds.
This effort is being driven by proposed EU standards for these metals in drinking water and food contact.

Glass- Fused-to- Steel) is a frequently used alternative name for vitreous enamel to describe the most durable coating for a storage tank or silo.

Depending upon the required functional coating characteristics, the applied enamel film may consist of 1, 2 or sometimes even 3 consecutive layers.
These tanks & silo’s are typically designed and manufactured according to AWWA D103-09 and/or ISO 28765.
Visited the Tecnargilla 2018 show in Rimini some weeks ago and saw there a new application method called “Steam Spraying”.

There are nowadays many different enameling processes.

Depending upon the annual production volume, it might be interesting to reduce labor cost by integrating all equipment of an enameling plant for water heaters and/or solar boilers.
Such integration may be done with traditional monorail conveyors in combination with automatic transfer devices, like on the picture below.

Alternatively a so-called power & free conveyor system may be used.
This conveyor type consist of two conveyor tracks above each other.
Example of power and free conveyor
On the lower level free cars may run, while via the power chain at the upper level the free cars may be (dis)connected and transported.
Nowadays there are P+F systems, which thanks to a very special transfer system even include the transport of products within the enameling furnace.
