Micro-pattern imprinting rolls for plastic film production




These days, we see more and more requests for a special imprint roll to which a replica sleeve is attached. These rolls are used to imprint micro-patterns on the surface of plastic film/sheet materials.

A replica sleeve precisely copies micro patterns from a master imprint mold, and it is produced at highly economical cost. Normally, a master mold tends to be so expensive since the micro-patterns are processed by a high-precision machining tool, and it requires a long working time.

Dymco invented a method to economically produce a lot of replica sleeves.

“Disposable” replica sleeves 



A replica sleeve is inserted to the roll



The merit of using a replica sleeve is that it can be replaced by another replica sleeve when the micro pattern is damaged. That reduces the running cost at the mass production.

DYMCO exhibits Highly-functional FILM EXPO 2019





We decided to exhibit at Tokyo Show this year,
December 4 to 6 at Makuhari Messe, Japan.
This is our 9th participation in this exhibitioin.
We are prerparing for belts, conveyors, and sleeves to be displayed there, including

Double steel belt heat press conveyor
Vacuum / Suction conveyor
Nickel Tiling Mold
Replica mold, and others

Pictures show 3 steps to make NIckel Tiling Mold

1.  Precise cutting of the 2-dimension stamper

2.  Welding cut pieces.
It looks like tiles are got together.
3.  All the cut pieces are welded to form a cylinder mold

 See you at the show!

DYMCO is working towards EMS, Environmental Management System Certification

 We have started operation activities for the first time to get certification of Environmental Management System　JIS Q 14001：2015（ISO 14001：2015).
The internal audit has already been completed in June.
Now we are in preparation of the initial assessment in August 
and are making steady efforts for the main assessment in September this year.

We will be a environmentally friendly company and 
care for environment more and more in our steel belt business.



The above picture is our Environmental Policy issued in March this year.

(1) We design, manufacture and sell environmentally friendly precision machined parts and related equipments.

(2) We will design and develop in consideration of the environment for resources and energy consumed or disposed by our business activities, and control or reduce them through alternative use of materials in an effort to prevent global warming.

(3) Capture the impact of business activities on the environment, and set goals within the range that is technically and economically possible.

(4) We will work to prevent pollution and work on environmental protection through resource exhaustion measures (energy saving, resource saving, use of renewable energy, mitigation of climate change (warm gas response)).

(5) In our business activities, we will comply with relevant environmental laws and regulations and environmental requirements to which we agree.

(6) We will work with related companies and partner companies to deepen their awareness of environmental issues.

(7) This environmental policy will be made known to all employees and publicized so as to be available to the general public.

Message from Tetsuo Taga, the president of DYMCO /a steel belt supplier


Message from Tetsuo Taga, the president of DYMCO /a steel belt supplier



DYMCO　has born in the last era of Showa, run through Heisei era, and plays now　a part of steel belt business in this Reiwa era.

On June 21 this year, we celebrated our 34th anniversary of company foundation.

We appreciate all of you who helped us in many ways. Please accept my thank-you to all of you again.

While getting used to era name Reiwa（implying peace & refreshing）, I am worried about the bogus reality of Work-style reform, or too much mention of power harassment lacking truthful meaning.

The essence of work-style reform is advanced productivity through work improvement. The sales promotion shall be achieved under the conditions of reduced working hours.

I am sure that the reduction of overtime work shall not be the sole purpose of work-style reform.　Spoiling employee does not equal to prepare a good work condition. Loose regulations tend to lead employee to self-deception with low productivity. It is my opinion that true work-style reform shall be a human resource development conforming to market fluctuation, and continuous effort to improve work-life balance is essential for company management. Experiencing hard-working time in one’s twenties or thirties having strong physical strength, vitality, and mental power will reward the person with the capability to conduct himself well when physical strength is declining later. A leading person endeavor to develop himself inconspicuously. A principle rooted in my mind is that excessive compliance deed and/or reversed power harassment shall be eradicated in DYMCO’s office.

Entering 34th financial year, I wish our service and products will contribute to your successful business conduct.

Thank you.

Continuous Monitoring on Wok Temperature - Double Steel Belt Heat PRess Machine

Continuous Monitoring on Wok Temperature - Double Steel Belt Heat Press Machine

Our Doubel Steel Belt Press and Heat, the picture below, has heating blocks in orange.
2 orange blocks in the upper conveyor.  The one on the left is for pre-heating.
Likewise there are 2 orange blocks in the lower conveyor. The one on the left is also for pre-heating.
There is clearance beween 2 heating blocks in the upper and other 2 heating blocks in the lower.
Load is applied from the upper blocks to the lower blocks.

 A workpiece such as resin goes through the clearance.
It is heated and softened between steel belts.
It is also pressed and its thickness becomes depth of clearance.
Finally it goes out.

Structure of Double Steel Belt Press and Heat

During this process workpiece temperature goes up in the beginning 
and then is kep same for a while.
This change of temperature is shown in the fiture below.
A Workpiece Temperature Curve in Double Belt Heat and Press


A workpiece is processed, but we cannot watch it temperature.
But it is clear by temperature logging.
This logging is possible when you come to DYMCO and make tests.

 If your try this test, please contact us.

Highly Precise Motion Realizedl by Stainless Steel Belt

Highly Precise Motion Realized by Stainless Steel Belt


Today's topic is metal open bands and open tapes.

 These stainless steel bands and tapes are often used for ball screw covers and scalar robots controls.
These are very popular applications.


 Still there is another application, 'Alpha Steel Belt.'
This belt is like the illustration below.
Both length ends of a belt are fixed.
A pulley is also fixed on a belt.
This pulley is directed connected with a servo motor axis.
When this motor rotates, this pulley also rotates and the belt is wound accordingly.
As a result both belt end fixed positions make linear motion, going right and lest in the illustration.
This linear motion is mechanically precise, thanks to this belt. 



Illustration: Stainless Steel Open Alpha Belt Linear Motion

Also we can fix attachment with a bolt on a hole in the belt so that this attachment makes linear motion.

To your questions, we do calculations to set belt specs and advise hole positions.  
Be free to contact us for belt motion and anything.
