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.

Hess Pumice Powders - Positive Alternative to Micro Beads

Hess Pumice Powders  -  Positive Alternative to Micro Beads

DYMCO is currently working on an "Environmental Management System" to obtain ISO14001 certification, so today I would like to talk about the environment from a different perspective.

DYMCO is a specialized manufacturer of steel belts that features high precision, flatness, and  smoothness.  In addition to it, we import and sell silica-based abrasives of the U.S. maker Hess Pumice Products Inc. as its Asian distributor.

Pumice of Hess is amorphous silica.
It is widely used as a polishing agent for glass and metal materials in Japan because it has relatively high hardness as silica type and high grinding efficiency.

But there is a change in reent years.
Hess pumice is getting attention as a micro beads substitute
as the movement of micro beads regulation has been strengthened in marine pollution and environmental protection.

Hess pumice, purely natural product, is environmentally friendly and harmless to the human bodies.
In the United States, we have a track record in the cosmetics field, mainly for face scrubs.

Hess's Pumice has a wide range of particle size line-up, about 50 types, from minimum average particle size from 3μm to 5mm.
This is realized by precise grinding and selection technology and strict quality control.

In addition, LHM, Low Heavy Mineral powders are also available.
Heavy minerals are less than 0.1%.

Samples can be provided free of charge, so please do not hesitate to contact us on Hess pumice powders.

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.
