Identification of enameling defects
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.
Bernd Reinmüller’s advice to coaters
Mr. Bernd Reinmüller of DIN (the German Institute for Standardization) was interviewed by Besser Lackieren and made the following interesting statement :
” Select only appropriate quality standards
and execute them correctly”
See https://www.besserlackieren.de/Technik-Produkte/Mess-Prueftechnik/Normen-richtig-nutzen for the full interview in German language.
Blisters
Blisters is a common enamel defect, which is characterized by appearance of circular holes & bubbles in a cooled enameled surface.
May occur as a group, cluster or line of blisters.
Blisters are typically caused by gas evolution during firing, as a consequence of :
- Poor steel quality
- Scratches or damage on base steel
- Large welding seams
- Insufficient cleaning
- Over pickling
- Over blasting
- Impurities in enamel
- Too thick enamel film
- Too high viscous frits
- Contamination of furnace atmosphere
- Under firing
Gas burners for Ferro enameling furnaces
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.
See http://industrial-enameling.shop for more info.
Preshipment inspections
Our technical services include conducting preshipment inspections for industrial enameling equipment.
Below an example of a batch type spray-degreaser, made of stainless steel, which we recently inspected.
Smart Industry opens a world of possibilities
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.

Flow-coating systems
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”

Fishscaling of porcelain/vitreous enamel coatings
Fishscaling
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.
