Manufacturing Process Flow for CE Certified 250 Micron Stainless Steel Mesh

The production of high-quality, CE certified 250 micron stainless steel mesh involves a meticulously controlled process to ensure uniformity, durability, and adherence to stringent standards. Unlike casting or forging, wire mesh is manufactured through a weaving process, often starting with wire drawing and then precise weaving or crimping.

Schematic Steps:

1. Raw Material Procurement & Inspection: High-grade stainless steel wire rods (e.g., AISI 304, 316) are sourced from certified suppliers. Incoming materials undergo stringent chemical composition analysis and mechanical testing (tensile strength, elongation) to ensure compliance with international standards like ASTM A276 or EN 10088. This step is critical for the base quality of ce certification 250 micron stainless steel mesh.
2. Wire Drawing: The raw wire rods are drawn through a series of dies to achieve the precise wire diameter required for 250-micron mesh (typically 0.16mm - 0.20mm). This process enhances the wire's tensile strength and surface finish. In-line laser micrometers monitor diameter consistency.
3. Annealing (Optional): Depending on desired flexibility and weave type, wires may undergo annealing to relieve internal stresses and optimize ductility for weaving.
4. Weaving/Crimping:
   • Weaving: Precision weaving looms interlace warp (longitudinal) and weft (transverse) wires to create the mesh structure. For 250-micron aperture, plain weave is commonly used, ensuring consistent square openings. Advanced looms are computer-controlled to maintain precise mesh count and aperture dimensions across the entire roll.
   • Crimping (for specific types): For specific applications, especially those requiring more robust and stable structures like ce certification square mesh wire fencing or certain ce certification heavy duty wire mesh, wires are pre-crimped (wavy) before weaving. This creates fixed intersections, enhancing rigidity and maintaining aperture size under stress. However, for 250 micron filtration, weaving typically achieves the precision needed.
5. Edge Treatment & Finishing: After weaving, the mesh edges are often finished to prevent fraying and ensure safe handling. This can include selvage edges, welded edges, or trimmed edges, depending on the final application.
6. Quality Control & Testing: Each batch undergoes rigorous inspection, including:
   • Aperture Size & Mesh Count Verification: Using optical comparators and precision calipers (e.g., ISO 9044).
   • Wire Diameter Measurement: Using digital micrometers.
   • Tensile Strength Testing: To confirm mechanical integrity of the woven structure (e.g., ASTM E8/E8M).
   • Visual Inspection: For defects such as loose wires, uneven weave, or surface imperfections.
   • Corrosion Resistance Testing: Salt spray tests or intergranular corrosion tests (for 316L) as per ISO 9227 or ASTM A262.
7. CE Marking & Documentation: Upon successful testing and verification against relevant EU directives (e.g., Machinery Directive, Low Voltage Directive, etc., as applicable to the final product form), the product is CE marked. Comprehensive technical documentation, including Declaration of Conformity and user manuals, is prepared.
8. Packaging & Dispatch: Finished mesh rolls are carefully packaged to prevent damage during transit, often with protective wrapping and robust cores, ready for delivery to target industries like petrochemical, metallurgy, and water supply & drainage.

The adherence to testing standards like ISO 9001 (Quality Management), ISO 9044 (Industrial wire screens — nominal sizes of openings and wire diameters), and in some cases, specific ANSI standards for screen performance, ensures the long-term service life and reliability of the mesh, demonstrating advantages in typical application scenarios like energy saving through efficient filtration and superior corrosion resistance in harsh environments.
