Enamel Rater (fully automatic)

Master Series

a highly flexible and cost effective solution for automatic enamel rating / metal exposure testing


For an auto enamel rater with a smaller footprint see the QA2600 Auto Enamel Rater

Enamel rating is a standard industry test that checks the integrity of protective lacquer/enamel on metal packaging. A can is filled with conductive electrolyte then a small voltage is passed between a test probe immersed in the electrolyte and contacts touching the metal of the can. The value of the resulting current flow indicates the degree of metal exposure or porosity in the coating.

  • BENEFITS
  • Sampling on time or production basis
  • Fully automatic can height adjustment
  • Accepts 202 to 211 body diameter without change parts
  • Standard or surfactant based electrolyte without modification
  • Data on screen and via local area network
  • Multi lane capability (optional)

Increase Efficiency

A fully automatic enamel rater relieves operators of the labor intensive manual coating porosity test, allowing more profitable use of time.

Improve Quality

The Automatic Enamel Rater tests each can for lacquer integrity in a precise and repeatable way without operator bias or error. Reliable metal exposure information is continually available with immediate on-screen warnings of potential problems, so prompt action can be taken. Data can also be linked into the factory’s process management system.

Reduce Spoilage

By relating sampling rates to production levels and previous results, enamel rating test frequencies can be set to match optimum output efficiency. Lacquer integrity checks are always made on time with immediate action, thus reducing the potential for manufacturing out-of-specification cans.
