WELD SEAM p r o t e c t i o n
for qual i t y c a n s
Effective protection of the weld seam is crucial to the
quality of a three-piece can. That’s why we offer a broad
range of seam protection technologies and systems.
After welding, the next step in the manufacture of a
quality can is the application of a durable protective
layer to the inner and outer seams.
Our powder-coating or wet-lacquering systems are
fully automated and can be customized to all system
configurations, production speeds and canbody sizes.
They guarantee easy, clean operation and low powder
or lacquer consumption.
