May 24, 2017 Property of Metal Belts

Metal belts have worked as solutions for unprecendented needs.
This is because metal belts own unique features as below:

1) Robust and hard
2) Rigid, not easily deformed nor elongate
3) High responsiveness.  Motor rotations and parts movements are precisely transferred.
4) Clean.  No lubicant is required for driving meal belts.  Dusts and dirt are quite limited.
5) Hygine.  Vacterials do not grow and smell of products are easily washed away.
6) Extremely flat.  Metal belt is a flat rotating stage due to belt engineering and flat metal material.
7) Extremely smooth surface.  Polished surface is also of your choice.
8) Heat resistive.  Available under heat of mor than 300 degrees.
9) Cold resist.  Metal belts rotates in 50 degrees C below zero.
10) Magnetism.  Due to magnetism of metal belts, drive and control by magnet are possible.
11) Resistance against corrosion and chemicals.
12) High precision. Critical tolerance is met.  High speed is possible.

It is sure that one of these features will help you to go to new manufacturing methos.

May 17, 2017 Continuous Inspection Stage- Rotating Platen

We have talked on our suction conveyor very often.
It is good at transporting paper and films.
Yet its belt surface is always flat due to a flat belt and suction.
It is just like platen, rotating platen.
In general belt surface fluctuation in Z direction is within 50 microns while the belt is rotating. 
This is the best tool for continuous inspection by camera or laser.
Please look at belt surface in this video.

May 10, 2017 Cylindrical Patterning Mold Replica- More in Detail

We know that fine-patterned molds are more often used in thermal imprint, UV imprint, and printed electronics.  And needs on replica molds are also increasing due to high cost of the original fine-patterned molds.

Upon these needs, DYMCO is working on development of replica molds.
The outstanding feature is that we can make cylindrical, seamless replica by the primary and secondary deposition and transfer.

We have tried this dimension.
Replica roll diameter: 120mm
Pattern width: 60mm
凹凸 height in pattern: 20 microns and less
This is reference, so contact us for size required.

Patterns on flat plates can be transferred on cylindrical rolls.
We do the primary and secondary deposition and transfer patterns by our electro-forming technology and finally weld them to make them rolls.

April 26, 2017 Film Handling: Low Inertia Roll / Video

Inertia Roll is driven by quite limited force.
Why is it possible?

This roll makes use of thin-wall Nickel sleeve on its surface.
When air goes into this roll, by this air thin-wall sleeve floats, which succeeds in limiting loss of rotational resistance mechanically.

Rotational resistance is expressed by inertia moment.
This resistance goes down to one fifties of rolls of the same size.

This is explained by this video.

Roll is heavy without air

Sleeve floats by air and rotates fast

Without air the roll needs several coins for rotation.

By air the sleeve floats and rotates by only one 1 gram coin.

If this roll is used for film conveyance, what happens?
When film goes on this roll, this roll begins to rotate and send this film to the next destination and does not give any other stress on film.

April.19, 2017 Merits and Applications of Metal Belts

We produce metal belts on custom.
Metal material is stainless steel mainly, including several grades.
Why do our customers choose metal belt rather than plastic and rubber belts?

They do because
・only limited dusts are found during operation nor frayed,
・belt surface is very flat,
・they are strong against heat, corrosion, and abrasion,
・stainless steell is hygiene, and
・metal belts do not elongate easily.

                         DYMCO, LTD URL

So, our customers choose our belt for driving arms, intermittent conveyance, continuous process flow rather than batch system, suction conveyance for web handling, and material heating and pressuring.

If you have a chance to come to Japan, please visit DYMCO.
we are about one hour from Tokyo or Haneda and can show you our belts and conveyors.

April 5, 2017 Patterning Mold Replica at Film Tech Japan @ Tokyo Big Sight

Fim Tech Japan is now open till April 7th this week.
Dymco presents tools for web handling.
One of them is replica of a patterning mold.
Patterning on film surfaxe crates uniques function on each film.
Patterns are made by laser and sharp drills, whick requires high-spec machine, jigs, time adn cost.
If it wears out, we need to make it again, spending a lot of time money once again.
Replica sleeves solve this issue.

We make replica sleeves from the original patterning mold.
At present its size and patterns are limited, but please try contact to us.
We will try.
3 sleeves on your right are replica sleeves, made from the original mold on the left
Replica is not a plate.  It is cylindeer, this is why patterning is done continuously as below.

Replica sleeve set on the air chuck roll for continuous patterning 
Replica sleeve set on 3 puleys for continuous patterning
