Plastic Film Cooling by a Face Touch Roll

 Plastic Film Cooling by a Face Touch Roll
 
Dymco has started to work from home as a measure against COVID-19. 
We continue to hold regular meetings inside our company by Microsoft  Teams. 
We attend them from home, completely avoiding contacts among members and spread of virus.
On the other hand, we have no choice but to come to the office for on-site works like improvements and evaluation of devices.
We would like to work on development themes efficiently,
although it is not certain how long this situation goes on.

Once in this blog I introduced Dymco's "cooling roll."
This roll is tripled.  From the outer surface, there are a thin electroformed sleeve, cooling water and rubber.
Cooling water flows in clearance between the outside sleeve and rubber. 
This rubber covers the core of this roll.

When this roll is pressed against the cooling target, the outside thin sleeve is pressed and creats face touch.
The performance depends on how much this face contact area is obtained.
In addition, we need to obtain data how much heat is removed by this roll.
So we are working to prepare evaluation equipment like the one in the picture below.
Cooling Test by Our Cooling Roll

We delivered φ100 × 950L for trial so far.
Now larger size is possible.
There is size restrictions in electroformed sleeves.
