Filter Mesh Component – Rubber and Plastic Product Manufacturing

Component Specifications

Definition

A precision filtration component used in polymer extrusion systems to remove solid contaminants, gels, and foreign particles from molten polymer streams. It consists of woven metal mesh screens mounted in filter housings or breaker plates, protecting downstream equipment and ensuring product quality by preventing defects in extruded plastic products.

Working Principle

Mechanical filtration through mesh apertures. Molten polymer flows through the mesh screen, where particles larger than the mesh opening size are trapped on the surface or within the screen layers, allowing only clean polymer to pass through to the extrusion die.

Materials

Stainless steel (AISI 304, 316, 316L), nickel alloys, or specialty metals for high-temperature and corrosive polymer applications. Mesh construction: plain weave, twill weave, or Dutch weave patterns.

Technical Parameters

Mesh Size 20-400 mesh (840-37 microns)
Wire Diameter 0.025-0.5 mm
Surface Finish Electropolished or passivated
Maximum Pressure 50-100 bar
Filtration Rating 10-500 microns
Operating Temperature Up to 450°C

Standards

ISO 9044, DIN 4187, ASTM E2016

Frequently Asked Questions

How often should filter mesh be replaced in extrusion systems?

Replacement frequency depends on polymer contamination levels, typically every 8-24 hours of operation. Continuous monitoring of pressure drop across the filter indicates when replacement is needed.

What mesh size is best for removing gels in polyolefin extrusion?

For gel removal in polyolefins, 60-100 mesh screens (250-149 microns) are commonly used, often in multi-layer configurations with progressively finer meshes.
