Cylindrical Stamper, Seamless Stamper, Reproduction of Stampers Mar. 30, 2018

Dymco exhibited Converting Technology Exhibition 2018 in Tokyo in February this year.
There our cylindrical stamper received attentions from visitors.

For one thing our stamper is not a flat plate, but cylindrical.
We make it by electroforming technology.
Therefore, our cylindrical stamper is completely seamless.
With this cylindrical stamper, stamping is performed continuously.

Another thing is that we can reproduce cylindrical stampers repeatedly,again by use of electroforming technology.
It results in significant reduce of stamper cost!

We can also manufacture the center hard roll, the core of the cylindrical stamper.
For stampers, we can help you.

Packing Case of Metal Bands Mar. 23, 2018

When we ship metal bands, we pack them in cardboard boxes, plastic boxes, or wooden cases.
Cardboard, you may feel it is fragile for shipping overseas!
But those damages are very rare.  We use firm cardboard for export packing of metal bands.

Cardboard was first made in the U.K. as new material sustaining silk huts!  
It was breathable and good cushioning, the best for silk huts.
Later it spread to the U.S. and in 1909 its manufacturing started in Japan.

In environmental aspects  
cardboard is 100% natural and renewable products.
They finally come back to the earth.  

Our metal bands are thin and needs care when packing.
We select the best cardboard and packing material and send metal bands everyday overseas.

Why not upgrade by metal belts and metal belt conveyors? Mar. 19, 2018

In the daily inquiries, we often see customers who try the metal belt for the first time.
So, today I listed the general advantages of metal belts.

1) Low risk of contamination. Unlike plastic belts, metal belts make little dust and fray come out from its surface.
2) The metal belt features very flat and smooth surface.
3) The metal belt is heat resistant, corrosion resistant, and, wear resistant.   
4) The metal belt is sanitary, and suitable for a food conveyor. 
5) Elongation of metal belts is very limited, which contributes the high precision power transmission and transportation.

The applications of the metal belt are power transmission in robot arms, high precision intermittent /continues conveyors.
Recently, we also receive number of inquiries for the process systems developed from metal belt conveyors, such as vacuum conveyors and double belt press conveyors.
For the vacuum conveyors and double belt press conveyors, we have demonstration conveyors in our laboratory. trials and tests are available on these conveyors.
On our new double belt press demonstration conveyor (Double Press No.2), maximum pressure is up to 3000kgf, maximum temperature is up to 250 degrees Celsius on the belt surface, and the belts are 400mm wide.
Additionally, cooling process is available on our Double Press No.2 as well as heating.
The detail of Double Press No.2 will be uploaded on our website soon.

We provide a questionnaire to summarize the of the customers’ requirements.
We can provide design the belt and the strength calculation through the information on the questionnaire.

If you are interested in metal belts, please do not hesitate to contact us.
We are open to any requests or questions.
Looking forward to hearing an inquiry from you.

Steel Belt as Band Electrode Mar. 9, 2018

T-die method is one of the major ways to produce plastic films.
Thin melted plastic is extruded from the T-die and goes down to the chill roler.
At this point the band electrode or the wire is used to charge thin film to get it stick to the chill roller tight without generating bubbles. 

DYMCO supplies these band electrodes.
These bands are thin stainless steel open belts, thickness 50 micron meters.

Advantages of stainless steel belts as band electrodes are:

1. Ultra thin
2. Highly tensile

3. Belt edges are rounded.  No burrs.

Band Electrode, 50-micron thick stainless steel belts
One belt is wound on the original reel 

Also visit the blog of the last year on band electrode for details.

If you have problems with  the band elecrodes or wires you are using now,
we are more than welcome to hearing from you.
