Simple Air Roll to Elastic Cooling Roll

Simple Air Roll to Elastic Cooling Roll

 Air roll was developed about 20 years ago.
It was very simple structure.  The outside is a metal sleeve and inside air pressure is kept.
It has metal surface, yet possess elasticity like rubber.
Test unit to compare  "rigid cooling roll (front)" and
"elastic cooling roll  with a chiller (back)"
However, requirements are getting higher and more difficult in production of plastic sheets and films now.  
To this needs DYMCO succeeded to set a rubber roll inside the metal sleeve so that the air roll can stand different pressure.

Popular rigid rolls, their thickness is 7 to 8mm, very thick.
The metal sleeve thickness of our elastic rolls is only 0.2 to 0.3mm.
Thin surface brings superior heat transfer efficiency.
Also with nipping by thin metal, contact surface between the roll and film becomes wider.
All these contribute to cooling efficiency.  
We see a possibility that the cooling line becomes shorter.

Metal Belt Suction Conveyor

Metal Belt Suction Conveyor

Last December we exhibited Highly-Functional FILM EXPO at Makuhari Messe.
We had chances to have good discussion with many visitors.
Every year overseas visitors are increasing, especially from China.
We could guess there active markets and technical needs there.

Is it difficult to convey thin functional films in flat state.
Visitors having such an issue watched and touched the belt surface of our suction conveyor.
We felt various need are coming up as films are getting more functional and the total process becomes complicated.

DYMCO at Highly-functional FILM EXPO and our suction conveyor
Also displayed were disposable version of seamless molds and Double Belt Heat Press Unit.
We wanted to show that very expensive pattern molds can be replaced with its replica and that two metal belts can sandwich films to laminate them or to cause special features by heating and pressing.
If you have a chance to come to Yokohama, Japan, please try your visit to DYMCO.
You can test suction transport, heat and press transport, and touch various metal belt conveyors.

Great Potential in Metal Belts

Great Potential in Metal Belts

Our management and accountants often talk with people working banks and finacial industries. 
They pay attention to our metal belts, too,
for our belts are unique and great potential to creat new markets.
Those belts are like the ones in the pictures below.

Suction / Vacuum Conveyor for web handling 
Metal Sleeves for Film Forming
Our belts are expected to creat and handle new functional matrials.

10-Micron Thick Nickel Elctro-Formed Seamless Belt

10-Micron Thick Nickel Elctroformed Seamless Belt

Thickness is controlled in micron order.
Completely seamless cylinder.
These re features of our Nickel electroformed belts.

How are these benefits wonderful?
As rigidity is proportional to the cube of the thickness,
the thinner steel belt can go around the smaller diameter pulleys.
Belts are tensile and capable to accept bending stress.

Our stainless steel welded belts, thickness ranges 0.05t~0.6t (mm).
However, this time we challenged thinner belts by electroforming and made a sample of thickness only 10 microns.

The belt goes along with a rod of Φ5mm
Nickel Seamless Belt Sample 0.01t×100W×380L
10-micron thick
What will be applications of this belt?

A belt in a limited space such as in micro machines
Knife-edge, very small R belt
Thin-wall cylinder shell
Electromagnetic wave shielding films
Special molding dies

We will develop electroforming technology of Nickel belts.

New Year message from the president of Dymco

New Year message from Tetsuo Taga, the president of Dymco, a steel belt supplier:

Happy New Year

In the first new year of the Japanese calendar Reiwa, I sincerely thank all the people who supported Dymco in various opportunity.

In the spring of this year, the business application of anticipated 5G telecommunications standard will start with the active alignment and realignment of IT businesses including overseas partners.

Now in the new era of Reiwa, we encounter an industrial revolution equal to the Industrial Revolution in 18th century with this technology evolution.

The 5G system magnifies line speed and memory capacity 100 times compared with current 4G system, and accelerates the technology evolution.

On the other hand, Japanese schoolchildren’s reading comprehension level has fallen to 15th place in the international achievement survey. Japanese media picks up on this issue as the lack of ability to read and understand. I am worried a little about future. There must be some influence of computer network and smartphone. It is important for us to preserve carefully the thinking time in stead of instant reply obtained in 5G environment in order to maintain reading and understanding capability. Returning to the principle of the thing must be essential to avoid the ill effect of pursuing excessively convenient tools.

This year is the Year of the Rat. A rat is a prolific animal and the symbol of prosperity. My goal is also the inheritance of prosperous business to the next generation.

May the new year bring you prosperous opportunity and happiness!

2020 New Year’s Day

Tetsuo Taga / Dymco
