Heat and Cool, Heat after Cool. Heating and Cooling Double Steel Belt Press Conveyor

Heat and Cool, Heat after Cool.  Heating and Cooling Double Steel Belt Press Conveyor

It is getting colder in Yokohama, although it was very warm in November and the early December.
The old Chinese people divided one year into 24 seasons.
December 7th was the beginning of the 24th season, very cold winter days.
But now we have air conditioners and other tools to live in comfort.

Among many conveyor types we have, Double Steel Belt Heat and Press Conveyor ranks the 1st or the second.
This machine was fairly large, for example pulley diameter was nearly 1 meter.
But Dymco came into this market with thinner belts and compact machines.
Ours is light and no need to prepare for a big space.
Please look at the picture below.  This has many functions.

Double Belt Heat Press Conveyor: Heat and Cool Type

Functions are
(1) Automatic Tracking
(2) Automatic Management of Clearance between the 2 belts
(3) Automatic Setting of Pressure
(4) Heating Control
(5) Cooling System
(6) Control of Belt Speed, and so forth.

Functions of (4) and (5) enables Heat and Cool or Cool after Heat.
The very important thing here is that steel belts are a key.

Let's look at how the work goes through this system.

Structure of Double Steel Belt Heat Pres System

First on the left the blue work is pre-heated.
Plastics, for example, is softened here.
It further goes into the heating area and it becomes lower and narrower.
It finally reaches the required thickness by pressing.

The work is kept heated and pressurized and goes into the cooling zone.
The work is hardened and formed as expected.

You know the word 'springback?  
Material, in general, inflates and deforms when it is released from pressure after being heated.
But our system avoids springback ! and makes the expected size and shape.

We also study adequate cooling so that springin does not take place in excessive cooling.

The picture below focus on passing from the red heating section to the blue cooling section.
area. 
This is a key in forming.

Heating to Cooling in Double Steel Belt System

This way our system is multi-functions.
Please utilize our system for your development and research.

If you have a chance to make the new system, you can choose combination of pressing blocks.

Combination 1.  Heat and Cool Press, like the conventional

Combination 2. Heat and High-Heat Heavy Press

                          After heating follows heating with higher temperature and pressure

Combination 3. Heat and Press

Combination 4. Cool and Press, for material already heated in a kneader, for example

The reuse of plastic waste to enhace the productivity of plastic products

The reuse of plastic waste to enhace the productivity of plastic products

Hello,
I am SAKUMA  from Dymco, Ltd.

We succeed in the test of forming plastic waste into sheets!
Nowadays, One of the enviromental issues called "microplastic" is causing the marine pollution leading the threat to ecosystem in the United States.
In the country,  the government comes out with a proposal that refrains from using plastic such as plastic strew in a coffee shop.
This proposal is now a huge issue and is about to affect the general public.
I believe Plastic manufacturers are in the situation where they are urging the development of eco-freindly plastic such as bioplastic.

Anyway,
The advantages of our stainless steel belts are "flatness" and "rigidity".
By using the advantages,  our stainless steel belt plays a role in a continuous forming mold to form plastic waste into thin sheets.
The first step is to heat a dozen of plastic waste that are crushed into pieces.
The next step is to sandwitch the object with our stainless belts.
And finally we succeed in this test. 

Steel belts have three elements required for plastic molding and can realize continuous forming.
The three elements are as follows,
1. Heat
2. Pressure
3. Time

Since 2016, We have collaborated with professor Mr. Takahashi from college of Industrial technology, Nihon University.
As one of the uses of waste plastic, we are studying continuous heat press forming of plastic waste granules with our stainless steel belts.

The video below has the detail of the experiment.
If you have an interest in recycling or reusing waste plastic, please find out our Double press heating system.

Test 1.  Continuous heat press-forming of the plasitc waste granules with Double press conveyor 

Test 2.  Continuous heat press-forming of the plasitc waste granules with Double press conveyor 

The plastic waste piled up through the hand-craft vibration hopper are put into lower stage of the double belt (See the video, test 1.)

The conveyor heats and pressures the plastics so that they are melted down, and after that the platics are cooled down to be the form of a solid plate. Finally, the platics are released from the conveyor( See the video, test 2.)

The conditions of the test is as below,

Belt speed: 0.1 m/min
Temperture of heater: 300～350°C
(both upper one and bottome one)
Belt thickness: 0.3mm
Belt width: 150mm

The belts are being coated with fluororesin to enhance the surface releasing ability, preventing any object from being sticked when it is hot.  This is why you see the surface of belt in black.
The lower side of conveyor lenghth is longer than the upper side.  A hopper and stage is prepared for the space to set the object into the conveyor.
Pre-heating is not filmed in the video.

In the conveyor, pre-heating device is set on the stage between the hopper and the belt pressure zone.

Try Dymco's stainless steel belts!

Try Dymco's stainless steel belts! 

Hello,
I am Saotome working for Dymco's sales depertment.

Recently, it is definetly getting colder in Yokohama.
I feel it is in the middle of winter.  
I hope I will get all over the winter with the heater I bought.
Stay warm you guys!

Anyway,
One of my major tasks here is to pack up our products before shipping.
When I try to pack up them, there are a few important things I belive to do.
One of the things is "seeing products with my own eyes before packing".
When it comes to processing stainless steel belts, tiny dirt tends to stick on these belts.
I check with my own eyes if there is any dirt on these.
Aafter that, next step is to wipe it off with alchole spray until the belts goes as shiny as it can be.
My final goal is to make our belts look as beautiful as they couldn't help touching and using the belts.

I am very glad if my job, packing and inspecting carefully the goods one by one, helps to go up the customer satisfaction.

Stainless steel belt has numorous shape, size and etc..
Moreover, the application is very wide depending on the cutomers.

We try to offer items that satisfy our customers demand.
If you have any interest or question and so forth, feel free to contact us.

Finally,  Dymco will exhibit in 9th Highly-functional FILM EXPO at Makuhari Messe.
Our booth is  4 hall  22-36.
We are looking forwards to seeing you there.
