OPTIMAGS Test/ or Toll Manufacturing low to medium volume bulk ware
In October 2004 OPTIMAGS completed its coating pilot plant at its premises in Karlsruhe. The predominant part of
this plant is a table top coating machine MBCD 1.3 ( top right ), and a bigger PA 240 – 5,5 m Coating machine for low
low volume production both machines work with the patented ultraprecise OPTIMAGS Knife Coater. The machines , as
pictured, are congruent scale downs of our big coating machines, and as such do, have the same drying concept as these
big machines.
The machines permit extreme clean coatings, even though being situated in a room of
just class D. Therefore, coatings can be done for the electronic and data recording industry, as well as for the
pharmaceutical industry.
The entire plant, or just the coating machine may be booked on a daily basis. Yet, OPTIMAGS
may also coat webs on a toll basis . Amounts may be in the range from single coils of minimum 100 m lengths, up to low
volumes of up to several 1000 m length. Both machines can produce multiple layer laminates with or without intermediate
process liners.
