The manufacturing process of metal packing mesh is a critical step in producing high-performance tower internal components widely used in chemical, petrochemical, and environmental engineering. Here’s a detailed breakdown of each stage. First, raw material preparation: high-quality stainless steel (304, 316) or titanium sheets are selected for their corrosion resistance and strength. These sheets undergo cold rolling to achieve the desired thickness, followed by precise cutting into uniform blanks using laser cutting or water jet techniques. Next is the forming process, which determines the mesh’s structural properties. Common methods include stamping to create regular porous patterns or weaving for a flexible, interlaced structure, ensuring consistent pore size and wall thickness. Advanced machines like CNC formers guarantee tight dimensional tolerances. Surface treatment is next: pickling removes oxide layers, while electrolytic polishing enhances surface smoothness, reducing fluid resistance. Some products undergo coating (e.g., PTFE) to boost chemical stability. Finally, quality inspection: each batch is tested for tensile strength, corrosion resistance via salt spray tests, and structural integrity using 3D scanning. This meticulous process ensures metal packing mesh meets strict industrial standards, delivering efficient mass transfer and long service life in tower internals.
