Identifying the correct type of enamel defect is the first & perhaps most important step when troubleshooting industrial enameling processes.
For this purpose we have invested in a digital microscoop and associated software.
Below some images of common enameling defects.
One of our relations would like to sell off their gas fired enameling furnace, brand Emisan.
The main characteristics of this furnace read as follows :
Hotzone length : 12,6 m
Maximum production : 1400 kg gr/hr
Firing cube : 730 x 700 x 760 mm
Installed energy : 600,000 kCal/h
Radiant tubes : 10
Temperature zones : 4
Please feel free to contact us, if you need any further information and/or assistance.
Ditmer Trading & Consulting BV developed together with Alpha Robotica & Franken Techniek two semi automatic flow coating machines for wet enameling the in- & outside of complex shaped heat exchangers.

Stordy/Hauck gas burners of Ferro enameling furnaces are operated with cold combustion air and have therefore low NOx emissions.
These burners may run “forever” provided their setting are regularly checked and when applicable adjusted.
In case of any damage, we may provide all necessary spare parts for such burners.

The world is in anticipation of a fourth industrial revolution.
This revolution is driven by giant leaps in ICT innovation and promises to radically alter the face of industry in the coming decades.
Automated production systems using advanced robotics increasingly communicate with each other on detailed aspects of production, joining up hitherto fragmented manufacturing processes.
By linking all steps in the value chain, a world of possibilities opens for companies, old and new.

Last week we assisted a customer in the United Kingdom with replacing all radiant tubes of their vitreous enameling furnace. Continue reading “Replacement of radiant tubes”
Flow-coating is a very efficient method, which is frequently used for applying wet enamels on e.g. cookware & water tanks. Continue reading “Flow-coating systems”
Ditmer Trading & Consulting BV may assist with sourcing critical spare, wear & tear parts for Eisenmann enameling furnaces, such as burners, radiant tubes and flue gass tiles.
The consistent liquid enamel slip properties is a critical parameter at any automated wet application process.
Unfortunately enamel rheology is known to change easily under the influence of particle size, specific weight, temperature, milling additives and/or pretreatment chemicals.
Failure to maintain its properties within measurable tolerances, may result in inconsistent enamel layer thickness and eventually even enamel defects.
Do you really believe that you can “feel it” with your fingers as demonstrated on the picture below, or do you rather prefer a more precise testing method ?!
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.
