Why do we need to use the screen changer for plastic extruder
When extruding plastics, a contamination-free plastic melt is desired. Since contamination affects the quality of the product and impedes the operating process, it is essential to ensure a perfect filtration process and improve the quality of the plastic melt by using a melt filter. A perfect filtration performance without any deterioration of the melt quality is possible with the well-proven DEAO Screen Changers, a large variety of which is incorporated into plastic extrusion machines.

Hydraulic screen changer-non stop plate screen changer

non-stop plate screen changer, single plate screen changer, hydraulic screen changer with single plate type

Specification

1)Deao patented technology on the sealing system design. Automatic compensation on sealing gap can be realized during screen changing process.
2)Compatible with extruders for various polymers processing at high output.

3)Filtration screen diameter ranges from 70-360mm.

4)With highly precise design, the screen has good abrasive resistant, high pressure performance, ensuring large effective filtration area and improving filtration effect. It works well even under high temperature up to 300 ℃ and high pressure up to 50 MPa.
5)Screen changing time ≤ 2 seconds with pressure accumulator.
