Hess Pumice Sand for Chinchilla bathing

Hess Pumice Sand for Chinchilla bathing

Due to the emergency declaration, 
'work from home' was introduced in Dymco in the middle of April.
Now the declaration was lifted.
We adopt staggered working hours from June 1.

So we work together again at our office.
We are finding little by little difference and merits of working in the office and working from home.

The second and third wave are predicted.
Also typhoons are coming.
DYMCO is preparing for those cases to continue our sales and production.

DYMCO is famous for its steel belts,
but we are doing sales of other interesting products.
As an Asian distributor of Hess Pumice Products, Inc. in the US, 
we import and sell their silica powders as abrasives.
They are used mainly for polishing glasses, metals, etc., 
but we also sell their powders as ChillDust, a product used for chinchilla sand baths.
Chinchillas and hamsters keep their bodies clean by bathing in sand.
Please look at this video, Hess Pumice Sand for Chinchilla bathing.

If you are interested in this sand for pet care,

please contact us or email to overseas@dymco.co.jp

Tough Times Drive Chances

Tough Times Drive Chances

May breeze has gone and we are in a rainy season here in Yokohama.


The first half of 2020 has been covered by news of "COVID-19, " the invisible new virus. 
We, DYMCO members, have taken preventive measures against infection.
We  adopted working from home and changing commuting hours.

We look at needs of masks and protective closing and 
think how we can help to ease this situation even a bit by our stainless steel belts.

Our belts are used in clean rooms.
Miscellaneous bacteria do not grow on our meltal belts.
If you have metal belts in mind in your applicataion,
Please contact us or email to overseas@dymco.co.jp

Relationship between steel belt and pulley diameter

Relationship between steel belt and pulley diameter


Various thicknesses and types of steel belts are chosen for each usage.
Then what about pulley diameter?
A large pulley is chose for a thick belt and a small one for a thin belt.
Here is a guideline in the technical information of Dymco's web site.


For power transmission open end belts,
pulley diameter = thickness x 400
example: belt thickness 0.1mm x 400 = pulley diameter 40mm

For welded type conveyor belts,
pulley diameter = thickness x 700

But when there are holes in the conveyor belt,
we recommend pulley diameter = thickness x 800
 
The graph below shows this relationship for conveyor belts.


                                                   Y:Belt thickness X:Pulley diameter

Yellow and green lines need smaller diameter than red and blue lines.
Yellow and green are stronger belts against bending stress than red and blue belts.

If you want to extend life of steel belts,
try to use larger pulley diameter than this guideline.

But when a load is not much, smaller diameter may be possible.

We recommend the best belt and pulley dimension for your application based on our stress calculation.

High Friction Pads - Effects and Manufacturing Method

High Friction Pads - Effects and Manufacturing Method 

The Covid-19 is widespread globaly.
Many people get infected or even lose their lives.
In the beginning I thought it might be same as flu,
but it is a very horrifying virus, invisible and recognized only by electronic microscope.
We hope effective medicine and vaccination will be delveloped so soon.
 
Today I talk about surface treatments.
Have you ever heard of Tungsten carbide?
It is possible to creat high friction surface by spraying these particles onto the part.
 
High friction is realized by minute carbide metal protrusions after spraying.
These protrusions are super hard and have excellent wear resistance.
They firmly adhere to the part or the substrate.
 
This surface can be made on a limited area of the parts where wear resistance is required.
Both surface of shims can be wear resistant, too.
 
High friction surface, why is it demanded?

(1)  make only limited area of the part anti friction and non-slip
(2) fasten the bolt tight and non loose by adding a ring shaped sheet
(3) make smaller and lighter the fastening part where a large amount of inertia is applied
 
Our customers adopt this furface aiming at these effects.

Ultra Thin High Friction Pads and Sheets
 
Please contact Dymco for small and thin parts requiring wear resistance.

Easy-to-Clean Metal Belt Food Conveyor

Easy-to-Clean Meta Belt Food Conveyor

Emergency declaration was lifted here in Japan yesterday.

Still COVID-19 threat exists. 
In DYMCO we continue to work from home and make use of web conferences.
Social distance, masks, ventilation, and washing hands have become are our new behaviors.

In such a situation, we feel motivation is growing to keep clean transport equipment especially in the food and medical industries.

Easy to clean is our  “Food Steel Belt Conveyor
The belt, frames and all parts are made of stainless steel.
Disassembly, cleaning and washing are very easy.
 
DYMCO Steel Belt Conveyor for Food Hygiene Management
 
There is little 凹凸 on the stainless steel belt surface.
Please wipe with alcohol or wash with water at the end of work.
The belt is soon dry and kept clean.

Also, by additional surface treatments other functions may be acquired on the belt.
This is an issue to be discussed.
Please contact us or email to overseas@dymco.co.jp

Over 50 Rich Grades Variations - Hess Pumice Amorphous Precision Abrasives

Over 50 Rich Grades Variations - Hess Pumice Amorphous Precision Abrasives

Dymco is a steel belt maker. 

We are proud of precision, flatness, and smoothness of our belts., etc.

We also work as the Asian representative of Hess Pumice Products in the United States,
importing to Japan and exporting to Asia their silica abrasives.

Pumice of Hess is non-crystalline silica and harmless to human bodies.
It is harder than other silica powders, resulting in higher grinding efficiency.
This is used as abrasives for glasses and metals in Japan and PCB substrates in Asia.

Hess Pumice Production Site

There are many long processes in polishing from rough to intermediate and finish.
Also, some users target to improve surface roughness, 
while others target to remove deposits.
Hess abrasives lineup ranges from the minimum average particle 3 microns and
includes many grades (particle size distribution) exceeding 50.

Customers can choose the most suitable grade according to usage, polishing objects, purpose, process, etc.

Hess also offers the low heavy mineral powders.
Heavy minerals in abrasives are just 0.1% or even less by their precise crushing,
selection technology and strict quality control.
It is possible to provide the samples free of charge,
so please be free to contact us overseas@dymco.co.jp

Hygienic Stainless Steel Belt

                                                  Hygienic Stainless Steel Belt

We are facing COVID-19 now.  This is fight against virus.

In the food industry have been repeated food poisoning and food product contamination due to bacteria growth.

One reason is hygiene management on food process machines and food transport systems.

Generally, we can clean metal much more easily than organic materials like resin and rubber.
Especially stainless steel demonstrated little possibility of rusts.
So this metal has been used in the food processing industry and water related parts like sinks and faucets.
 
DYMCO is an expert of stainless steel belts.
Our belts are hygiene and emit little dusts, serving as a good transport tool in the food industry and clean-room operations.
