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.

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.

Smart industry

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.

Enamel slip properties

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 ?!
