Product Description

Plate type hydraulic screen changer for three layer co-extrusion sheet extrusion line

The features of the drip irrigation pipe extrusion line
1, the melt pressure is high, it requires the screen changer /melt filter with high pressure resistant
2, the product is pipe, so the production process is continuous will be better, thus we need a continuous type of screen changer which do not impact the production when cahnge the screen.

Based above features, the screen changer fits for the drip irrigation pipe extrusion machine must be high pressure resistant and continuous type without interrupt production when change the screen.

Actually we have a kind of screen changer owns thes fearturesand advantages:
Widely used hydraulic screen changer for polymer melt filtration

This kind of screen changer can work with high performance under the pressure 50 Mpa, nd also a continuous type.
So it is the best choice for the drip irrigation extrusion machine.

The following picture show the raw materials and the semi-products of our screen changer
