Fishscaling is an enameling defect, which is characterized by small enamel particles chipping off.
Chipping off may happen directly after firing when cooling down or sometimes even days later.
Effected products may usually not be repaired. Due to this reason, this defect is still one of the most described topics within the international enameling industry.

Received earlier today a new batch of “Porcelain (Vitreous) Enamels and Industrial Enamelling Processes” book.
This classic reference book, which describes in detail many aspects of vitreous enameling technology & equipment is a must for every professional enamelist.
Please note that the current edition is nearly sold out !
This excellent book and other literature about vitreous enameling technology, may be found at our webshop (https://dtc-webshop.com) .
The latest ISO 9001 version 2015 puts a lot of emphasizes on managing competences & risks. Continue reading “Managing competences acc. to ISO 9001”
The Italian National Unification institute has published UNI 11734 as of December 6, 2018.
This standard specifies a method for measuring the hydrogen diffusion coefficient in order to determine the fish-scale susceptibility of steels, which can be used in the enamelling process. Continue reading “UNI 11734 : Determining fish-scale susceptibility of enameling steel”
The performance of industrial enameling furnaces may gradually decline over time.
This may result in higher energy consumption (read increased enameling cost) and reduced quality of the coated surface.
In extreme cases the enameling furnace may even unexpectedly break down, because insulation has been damaged and/or worn out.
Therefore we suggest regular inspections & thermal imaging to identify major heat bridges and other spots with possible insulation issues.
DTC may conduct energy audits to identify possible energy savings at your vitreous enameling plant, thanks to our broad knowledge and hands-on experience with industrial enameling processes & equipment since 1984.

The European Energy Efficiency Directive (2012/27/EU), also known as the EED, was established in 2012.
The aim of this Directive is to help to realise the European target set in 2007 to reduce European energy consumption by 20% by 2020.
This should contribute to a reduction in greenhouse gas and air pollutants, to a decrease of energy costs, and to lower dependence on import of fossil fuel.

With ultrasonic thickness measurement, you may detect the thickness of individual layers within a multi layer coating.
This may be of great help, when troubleshooting e.g. a two coats / one fire vitreous enameling process.
See our webshop for more details about this and other film thickness gauges.
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.
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.
DTC may assist with the evaluation, which solution is most suitable for your vitreous enameling project.
DTC will attend the 24th International Enamellers Congress, which will be held in Chicago from May 28 till 31, 2018, and present a technical paper about managing essential (enameling) know-how.
