Automatic enameling plant for water heaters

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.

Wet enamel application

Porcelain enamel may be applied via a variety of wet application methods, such as dipping, flow-coating, slushing and spraying.

Originally application of porcelain enamel was done manually, as shown at the pictures below.

With increasing labor cost and production volumes, manual application was replaced by automatic application. In order to reduce enameling cost and/or improve the coating quality, more advanced applications systems, such as electrostatic wet spraying, robot spraying and electrophoresis, where introduced in the 50’s and 60’s.

Old fashioned electrostatic wet enamel spraying system

Nowadays wet enamel is typically used for small production runs (of special colors), special enamels and/or when the product design isn’t suitable for electrostatic dry application.

Well-know liquid enamel application equipment producers include : Binks, Devilbiss, ECCO, EIC, Eisenmann, Fisher, Sames, VGT.

DTC may assist you to evaluate, which application method and/or equipment is most suitable for your products, and if required also help you with sourcing / procuring the appropriate machines.
