Robot Arm Driving Belt in Vacuum

We are getting more and more inquiries on vacuum environment.
In this field DYMCO is capable to suggest solutions to driving belts, which control motion of pick-and-place robot arms.

We find encouraging advantages of stainless steel open bands for finer manufacturing like semiconductor device.

(1) Metal open bands are very thin.  Compact and very light units are made.

(2) Metal bands are rigid and show little elongation.
     Speed for drive and halt can be increased.  Speedy motions are realized.

(3) Removal of backlash.  Band length ends can be fixed on a pulley.

(4) Vibrations are limited when arms rotate or halt.  Driving noises are also low.  
     Metal open bands work without a drop of oil.

(5)  Stainless steel bands are tough against heat, corrosion and abrasion.
      Also limited dusts and out gas are good reasons of choice 
      in vacuum, under heat, and in clean rooms.

Given your layout or working conditions we suggest belt specs or layout to you.

Suitable method for continuous printing, and processing on paper, films, sheets.

When printing or processing continuously on the surface of a film, sheet, paper, etc., if the film stretches, moves or waves, it will not be possible to perform accurate printing or processing.

In those cases, Dymco's Vacuum/Suction Steel Belt Conveyor can help to perform accurate printing and processing.
This is because Dymco's Vacuum/Suction Steel Belt Conveyor does not transport the film by pulling force of winding rolls, but by holding it on a flat and smooth steel belt by suction.

The film is transported while the entire film is adhered on a flat and smooth steel belt by suction. So, the film can be transported smoothly and quietly without applying excessive force. As a result, accurate printing and processing will be possible.

DYMCO's Vacuum / Suction Steel Belt Conveyor can be applied to lot more interesting applications.

We are looking forward to hearing your interesting ideas on how to use DYMCO’s Vacuum/Suction Conveyor.

New Application of Low Inertial Roll, 'Film Touch Roll'

New Application of Low Inertial Roll, 'Film Touch Roll'

We hope that you are familiar with our low inertial roll.
It has been shown in many exhibition so far,
yet it is being improved still now.

The illustration below explains its priciple.
The outer surface is a thin electro-formed Nickel sleeve.
Due to comprssed air this thin sleeve floats off the cylinder and rotates.
Mechanical rotational resistance loss is kept to a minimum.

As its application, 'touch roll ' is expected.

We made φ100×1200L to our customer.
Various size is to be discussed.


Meatl Belt DYMCO at Exhibitions

Metal Belt DYMCO at Exhibitions

We have joined exhibitions many times including High-Functional Film Show and Converting Technology show.  We work on booth design and enjoy it.

Until last year the base color was whit or blue like DYMCO logo.
In February this year at Int'l Secondary Battery Show at Tokyo Big Sight,
we adopted orange for the base color as shown in a picture below.
Walls were full of product images and we used simple words that explained those products.
DYMCO looked different there, bright and active.

We continue to challenge booth design so that more and more people come to us.

Now coming is 
SNEC 13th (2019) International Photovoltaic Power Generation and Smart Energy Exhibition & Conference
June 4 to 6 this year at Shanghai New Int'l Expo Center.
We are at Hall E2  #112.

We are preparing for it.  Let's meet there.

DYMCO's Double Steel Belt Machines

Dymco’s main product is stainless steel belts, but customers contact us are often unfamiliar with steel belts and they try steel belts for the first time.
There are a lot of applications with steel belts, Double Steel Belt Press is one of them.

What this machine can do is;
- Continuous forming process of heating, press, and cooling. This cannot be done without a high thermal conductivity of steel belts.
- Processed workpiece can be flat 
- Line speed can be faster because the heat press continues for a long time.

Customers can give a test with our demonstration machines at our laboratory.

2 double belt press machines are available for the demonstrations.

The second machine operate under maximum pressure of 3,000 kg, maximum temperature of 250. The belts are 400mm wide and cooling unit is installed after the heat press section.

We are frequently asked for the higher temperature. In that case, the first machine is capable of 350. We hear the needs for higher pressure, too. We are working on the modification of the demonstration machine to respond these customers’ needs.

Dymco’s machines are all custom, we design each steel belt machine based on customers’ needs and requirements.

If you are interested in Dymco’s steel belt machines, feel free to visit us.

Anti-Reflection White Coating on Suction / Vacuum Conveyor Belt

Anti-Reflection White Coating on Suction / Vacuum Conveyor Belt

Spring has cone here!
And coating in the picture below is bright just like spring white flower.
"New Arrival" "Spring White"  Anti-Reflectio Coating

The belt in the picture is a perofated belt for suction conveyors.
Some customers use vacuum conveyors for image inspection.
At that time perforated belts are often coated to make clear contrast with the work.

Black coating is popular.
But it is not good for the work including carbon fiber.
So in this spring season I tried white coating and I love it.
Carbon-fiber works are clear on this. 

I am thinking of the next new sample.

Cylindrical Pattern Mold

Cylindrical Pattern Mold

Cherry blossoms are in full bloom in Yokohama.
We are enjoying spring flowers and warm air.

Today's topic is a pattern mold.
We support continuous patterning by cylinders and belts.
In other words we help our customers to go beyond sheet by sheet patterning in 2 ways.

First, Nickel welded cylinders
Some of our customers use Nickel patterned plates to perform sheet by sheet patterning.
We take out patterned areas from Nickel plates and weld these pieces to make a patterned cylinder.
We call it 'a tiling belt,' for patterned pieces are connected together.
Find the picture below.

Nickel plates are thin and a welded cylinder is also thin.
We make a core, too, so that this thin cylinder fits the roll core.
When the roll core rotates, outside patterned cylinder also rotates and patterns are transferred to materials.

Second, we can provide cylindrical substrates that press the work while patterns are transferred form the patterned roll to the work, like the blue belt below.

We provide both stainless steel and Nickel belts.
