Heat Transfer by Surface Contact / Dimco Cooling Roll for film forming

Heat Transfer by Surface Contact / Dymco Cooling Roll for film forming 

The Japanese people are becoming great rugby fans, enjoying every match of Rugby World Cup 2019 held in Japan.
It is a big news for us that Japan could join the best 8 teams for the first time.

Now back to DYMCO products, I introduce “Cooling Roll” today.
This is a special product in a way that the outer surface is has a thin-walled cylindrical metal sleeve completely seamless, without any seam.  Inside this sleeve lies a rubber-coated roll. 

Cooling water circulates In this clearance between the outside metal seamless roll and the inside rubber roll.

The cooling capacity depends on how much contact area can be gained when this cooling roll is pressed against the object to be cooled (usually a rigid roll).

Currently, we are setting parts and units to watch the actual heat transfer performance
and are making further improvements to meet the demands of users.

The upper roll is our cooling roll and the lower roll is a hard rigid roll

We have provided φ100 x 950L to a user for trial.
The larger size is producible.
Cooling roll size is sometimes restricted by size of the outer metal seamless sleeve.
But we welcome your questions and are looking forward to discussions with you.


DYMCO is tackling Japan's challenges, environmental issues and an aging society

DYMCO is tackling Japan's challenges, environmental issues and an aging society

Big typhoons have damaged many areas in our country this year.
Some say this is caused by global warming,
and that these big typhoons will come from now on, too.
At the same Japan's super aging society is also an important issue.
Together with young labor shortage, need of automation and  labor saving is increasing.
DYMCO face these issues.
We develop and sell devices or parts to support solutions, like
stringer belts to connect solar cells to form solar panels and
metal open bands driving scalar robots.
these also help automation and labor saving in handling thin materials.

FILM Expo is one of 6 exhibitions, covering functional materials in this Messe.
This is a big event with participation of over 1000 companies.

DYMCO demonstrate film handling conveyors below, employing metal belts.
-Suction/ Vacuum Conveyor
-Double steel belt Heat and Press Conveyor

You will find a variety of metal belts and sleeves, too.
Find tickets and details here.
We are expecting to meet you on this occasion.

Heating and Transport of Heated Parts and Material by Metal Belt Conveyor

Today's topic is heating metal belt conveyor.
We have provided metal belt conveyors for different purposes:

- Keep heated atmosphere
- Baking
- Dry powder
- Heating, heat treatment and softening of metal parts

Now DYMCO has one heating metal belt conveyor in the picture below.

We use this in our lab for tests with our customers.

The heating furnace is set over the transport surface, above the metal belt.
We set up heating temperature, transport speed and heating time.
This way we get results from different conditions.

Drying and Heating Metal Belt Conveyor / Belt Width 500mm  C-C 3000

In addition in our lab we have suction conveyor and transport under vacuum is tested.
If you are interested in these tests, try contact to us.

Folding and Perforation: Metal Open Band End Processing

Today we show examples of end processing on metal open band.
In the picture below, end folding on your left and perforation on your right. 

Folding and Perforation at Metal Open Band End
These belts are thickness 0.2mm.  Steel grade is SUS 304H.
This is spring type of stainless steel.
It endures repeated bendings around rollers and pulleys.
So these metal belts are used for power transmission and covers for actuators and protection of certain parts in machines.

4 holes are for fixing this end.
Normally we sandwich this end by unit (Assy) plate block and fix ends.

Ends in the picture are folded.  This is quite rare.  Usually they are straight and not folded.
But we do lots of process and live up to customers' request.
Our minimum lot of open band is one belt.

Vacuum Conveyor Application Video: Pulling in Film and Metal Foil / Tension Adjustment

We are focusing our sales on suction conveyor.

A conveyor, in general,  carry things.
In addition, suction conveyor can tow a continuous film, metal foil and metal strip under tension like in the video below.
In this test we applied tension by weight.
The degree of tension is adjusted easily by controlling suction.
Material is pulled without wrinkles and without vertical movement like the below.

In both sheet feeding and roll-to roll, films and metal foils are pulled on a belt by vacuum and those thin material stay flat on the belt.

Metal Belt Fluororesin Coating: Heat-resitance, Wear-resitance, and Non-adherent Property

We do Fluororesin coating on our stainless steell belts and we have increased kinds of coating as the picure below.


Hearing your needs, we choose types of Fluororesin.
In some coating heat-resistance is normal but non-adherent property is excellent.
In the other, abraion resistance stands out.
And the we coat that material on our metal belts and install them in our conveyors.

When you need to add functions on metal belts, please contact us.
In addition to the above examples, gray coating is also popular.
This coating cancel reflextion of stainless steel and is used for camera inspection.
