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.

DYMCO'S Vacuum Conveyor Serves Best for Varible Printing

                  DYMCO'S Vacuum Conveyor Serves Best for Varible Printing

SNS and email ads are popular, still we find direct mails in our posts.
Direct mails are made after printing different names and address on each mail.
This is what we call 'variable printing.' 
It is done by inkjet printing.  inkjet printing is written 'IJ' in short.
IJ automaticcally prints differrent info on each item.

 IJ does not use plates, fixed info, like offset press or gravure printing. 
IJ prints data and data is variable.
This is why inkjet can print different names, QR codes, IDs on every card and envelop.
Multi-product small lot is exactly the very feature of inkjet printing 
in contrast to offset press and gravure printing that print the same data in volume.

 Then what happens when you transport those cards and envelops fast enough in inkjet printing?
Due to wind pressure during transport,
corners and edges of these thin paper items may easily float, 
and they may deviate from the initial position.
These situations result in printing failure.

Landing positions of Picoliter-level ink drops are essential in inkjet printing.
This is same for IJ with UV inks.
Ink drops are shot aiming at certain X-Y positions.
But if their landing height is longer than aimed,
ink drops do not land at expected X-Y psitions, resulting poor images.

 Our vacuum conveyor sucks thin cards and envelops and transport them right under the inkjet head. 
Landing height is kept minimum even for thin material like paper and films.
This high-speed and precise transport is essential for variable printing.

Sometimes it is difficult to export the whole suction conveyor overseas.
But we will make metal suction/ vacuum belts and give advise for designing the vacuum cocnveyor.

Weld Seam of Stainless Steel Belt



Today, I would like to talk about weld seam of Dymco’s steel belts.
Dymco’s steel belts used in multiple applications – such as continuous inspection conveyors, vacuum conveyors, heating conveyors, food conveyors.
Among those applications, the double belt press conveyor – the continuous heat press unit sandwiches the workpiece between a pair of steel belts - is one of the applications requires a high quality in weld seam.

Dymco’s steel belt features a very flat weld seam at its regular finish. Though, with the additional polish on the weld seam, unevenness of the weld seam (height of the weld bead) can be less than 5 microns. Dymco fulfills the customers’ various requests with the suitable steel belt.

Tourist Attractions Around DYMCO

Tourist Attractions Around DYMCO

In July we celebrated our 34th anniversary on Entertainment Restaurant Ship 'Royal Wing.' 
The ship sailed through under Yokohama Bay Bridge and made a round of Yokohama Port.
As twilight covers the sky, night views of Yokohama spread out in front of us. 
It was so beautiful.
Here is a picture of the night.

We sometimes have overseas visitors.
We show them or belts and conveyors.
When visitors bring their work, we test them on our vacuum conveyors, for instance.

If you have a chance to visit Japan, we suggest your coming to DYMCO first and why not enjoy night views of YOKOHAMA after?

DYMCO's Precision Welded Tubes




Dymco’s stainless steel endless belts are manufactured by the highly skilled precision welding technology. Regardless of the materials’ thickness, Dymco’s stainless steel belts are not lap-welded, but butt-welded.

Applying its highly skilled welding technology, Dymco manufactures welded tubes with the very high dimensional precision.
The pictures below are a doubled tube; Inner dimeter of the outer tube is φ300.03+/-0.01mm. The inner tube is inserted inside the outer tube, of which outer dimeter is the φ300.00+/-0.01mm. There is no clearance between inner and outer tubes. The both tubes are 0.2mm thick and tolerances for inner/outer diameter is +/-0.01mm.

Each tube has only one weld seam in circumference.



Outer tube: IDφ300.03mm




Inner tube: ODφ300.00mm



Dymco’s welded tubes features very thin wall, flexibility, and light weight. Therefore, these tubes are frequently used as covers.
Please feel free to contact us if you are interested in Dymco’s precision thin-wall welding technology.

An Option to Replace Plastic Disposables: Thin Metal Cylinder


In April this year, Nikkei, one of the Japanese leading newspapers, reported,
"P&G and other firms try reuse of metal containers.
An action to reduce plastics in daily necessities."

 Most liquid detergent and shampoo / rinse containers are made of plastic.
But being sought are using recycled plastic and changing to metal containers that can be used repeatedly.

 Challenge of P&G:  Aluminum bottles in NewYork and Paris

Look at the picture below.


Stainless Sleeve, thickness 30 microns

For welded metal cylinders, we can contol their dimeter by 0.1mm .

These technologies to make thin metal cylinders may assist to replace plastic containers.
