Zhengzhou Deao Science & Technology Co Ltd is a professional screen changer research and development manufacturer. 

In order to choice suitable screen changer , we need below informations:

1. What`s material ? PE or PA , PC and so on ? Is it a new material or reclaim material?

2. Is the extruder single screw or twin screw?  What size is the screw diameter?

3. Production capacity (Kg/h)?  Max operating pressure Mpa ?

4. What is the finished goods, pipe or sheet,granulating ?

5. Have you been used screen changer ? how about filter area ? How long changed screen frequency ?

6. Do you require continuous or discontinuous when building ?

According to your production status, we will choice suitable screen changer for you

Screen changer is connected between extruder and die mold,  it can filter impurities , ensuring  production  not stopped, the material is not leaked, the quality and the efficiency of the product are improved, and the high profit value is created for you.

Granulationg ,Plate making , blown film, cast film, sheet, pipes, collosols, rubber and chemical fiber, No-woven and so on

1. Don`t stop machine when changing screen, continuous produce, material doesn`t  leak. 

2. Improve  quality of the finished goods

3. Improve production efficiency

4. Make product visual  become more beautiful 

1.Make the output pressure stable

2. Improve  quality of the finished goods

3. Increase extrusion output

4.Extend the whole machine life

1. At any time, it is not allowed to install and disassemble the filter net and adjust the structure when the oil pump motor rotates.

2. When the equipment is left unused for many days and re-start, it is necessary to first check whether the operation of the change-in device is sensitive and reliable.

3. It is strictly forbidden to push and pull the filter screen quickly under the condition of high temperature and no lubrication to prevent each fit surface from being pulled.

4. In normal production, there should be a small amount of molten material overflow on both sides of the skateboard. In order to facilitate lubrication, if there is no overflow or new installation, the skateboard should be lubricated with silicone oil when changing the net.

5. If there is a failure, should stop in time, please experienced maintenance personnel to check and repair, strictly forbid to work with fault.

6 .Do not disassemble the screen changer and the melt gear pump, any questions, please contact us.

7. Electricity protection, fire prevention, scald prevention.
