Plastic extrusion machine screen exchange filter
Single plate screen changer, slide plate screen changer, hydraulic screen changer
Why do we need the screen changer for our extrusion machine?
hen 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.
Plasti extrusion machine screen exchange filter/the plate screen changer, is widely used for the production of various plastics and chemical fibers. It is of high performance/price ratio, and ensures the screen changing without machine halt, or any material leakage under high pressure. Therefore, it is especially applicable to large scale machines of film blowing, pipe making, plate making and granulating, etc.

Features of this kind of plastic extrusion machine screen exchange filter
1,Automatically compensates the sealed surface clearance( self-owned patent), matched with extruders of different specifications, it's applicable to process with most polymers, and high output
2, screen changing time is within 2 seconds, and screening area covers fromΦ70 to 300
3,Mounted both horizontally and vertically, the single plate screen changer can be introduced very successfully onto pre-existing installations or where the space available is restricted, but without compromising high quality processing
4,Several single plate screen changers can be controlled by the same hydraulic unit, resulting in large savings and maximum use of space
The applications
theDHB series a solution for granulation, re-granulation and regeneration installations as well as processing lines of blown films, bubble, films, casts, sheets, flat head plates, pipes, profiles, Hot Melt.
