Extrusion Screen Pack is a strong, durable and convenient solution for trouble-free processing. It prevents the unwanted particles to mix in the molten mass passing through the extrusion process. This screen is best fit for fine extrusion and helps in conducting more neat and clean extrusion.
The commonly used Extrusion screen pack is made from excellent quality stainless steel 316 and 304L grades mesh varying from 4 mesh to 500 mesh about 5 microns. It is widely used in the rubber and plastic industries.
The multi-layer extrusion screen packs are the variable wire meshes that are cut to specific shapes and sizes and then precisely assembled and spot welded with each other to produce multi-layer packs. The screen layers are assembled in the proper sequence to avoid any operation error.
Layers : 2 , 3 ,4, 5 or more layers
Material: Stainless steel grades (302, 304, 316, 316L) woven wire mesh, copper wire mesh, galvanized wire mesh and nickel alloys.
Shapes: Round, oval, rectangle, elliptical shape
Packs Diameter 20mm – 900mm
Frame style: With and without frame and spot welding
1. High strain ability
2. Filtration capacity
3. Precise fitting filter elements
4. Adequate cost-performance ratio
5. Durable and long performance life
6. Spot welded multilayer pack
8. High compressive strength
9. Excellent heat, rust and wear resistance
The wire mesh screens used in extruders are square mesh that have identical count of wires per inch in the both directions. They filter out the impurities and also build up pressure in the extruder.
Extrusion Screen Applications:
Very fine and thin extrusion process for high quality petrochemical, plastic, rubber, chemical, pharmaceutical, beverage, aeronautic industries and also in water processing plant and food processing industries.
