Extruder Screens and screen pack mostly used in Plastic Melt Filtration and Polymer Melt Filtration. It is essential in preventing contamination in the melted mass during the extrusion process. It is effect to keeps away mixing of foreign particles in finally equipped extrusion product and provide a clean and clear extrusion to use. Extruder Screens mostly used in Plastic Melt Filtration and Polymer Melt Filtration.

Applied to a variety of equipment, in order to meet different needs, extruder screens and screen packs with a range of sizes, shapes, meshes, and materials be needed which can be custom made.

Stainless steel material for make extruder screen

Stainless steel material for make extruder screen

Stainless steel is one of the most common raw materials used to produce mesh screen products. So we take stainless steel weaving as an example.

Common weave: Plain weave can be woven up to 400 mesh; Twill weave can be woven from 30-635mesh.
Common Width: 0.914m,1.0m,1.22m,1.5m,Special requirement can be customized.
Common Length: 30m, 30.5m. Others can be custom-made.

Due to high content of Ni and Cr, it is with good oxidation resistance, corrosion resistance, acid and alkali resistance, high temperature resistance. In short, the maximum service temperature is 1200.

Other main weave types:

Stainless steel wire cloth woven types

Stainless steel wire cloth woven types

Characteristics of stainless Steel Wire Mesh:

  1. Acid-resisting,alkali-resisting and anti-corrosion;
  2. High strength,good tension toughness and abrasion;
  3. performance,durable in use;
  4. resistance to high temperature oxidation;
  5. Highly polished, no need to do any surface treatment,with convenient and simple maintenance.
