Test center Coating Machine

We have started test coating service in our Numazu plant.

Installing Direct-Drive motors for not only coating unit back-up roll but also In Feed and Out Feed roll makes advantage of stabilizing web at coating point

Test result by quasi-PVA coating liquid. (Bird's eye view of Film thickness)

Test result

We conducted a test of quasi-PVA coating liquid using our pilot coating machine
(Die coating method) After application, we measured dried film thickness by optical
interferometry. And then, make film thickness distribution into bird's eye view.
We verified that average amount of film-thickness conducted by both way, low-viscosity
and high viscosity, are ±2%.
