RANGE OF IN LINE COATING
CONTROLERS
The ASM controlers are specifically designed for keeping
constant the density (ASM 2000 series), the viscosity (ASM
2500 series) or the combination of both density and viscosity
(ASM 3000 series) of anti-scratch and/or anti-fog coatings
used for the treatment of transparent substrates
All ASM systems control the level of the coating tank via
specific sensors.
As soon as the level in the tank falls under the reference
(either bacause of solvant evaporation or because of the
coating process itself, the system will refill the tank with
either base coating or solvant, depending on the actual value
of the controled parameter (density or viscosity) compared to
the set-point.

In most case, the ASM in-line controler comprizes:
one chassis on wheels that houses the control electronics, the
refill canisters (one for solvant,one for coating), the refill
pumps and valves and supports the color touch-screen
operator’s interface.
One in line sensor for density or viscosity per tank to be
controled
One set of non-contact level sensors per tank to be controled |
The color touch screen with multiple windows type of user
friendly
interface allows a simple but efficient control over the
process (View of main screen of the ASM 2000-1 system) |

WHY
SHOULD YOU USE ASM CONTROLERS ?
|
 |
|
Before: manual control |
After: automatic control |
By eliminating all operator’s interactions with the coating
process, with their inherent risks for mistakes
and by adding only by very small volume of either solvant or
coating (10 to 50 mL), the ASM controler drastically reduces
the fluctuation of the performances of the coating process.
Other inherent benefits are:
Eliminates the costly man-power required with manual
control(all refills and controls are automatic,day and night,
week end included)
Eliminates production down-time (the small quantity added to
the tank does not impact the coating process so that operation
can be continuous)
Eliminates all risk for coating mishandling situations such
as:
# chemical shock if a too large quantity of solvant is added
to the tank in one shot
# refill with the wrong chemical
# risk for the formation of air bubble s if the level becomes
to low Increase the consistency of the process Increase the
life time of the coating solution Allows to save on non
quality issues and rework |
