Custom Metallic Packing and Gaskets

Metallic packing and gaskets serve several industrial functions, including vapour-liquid separation, filtration, sealing, spacing, vibration damping, and exhaust decoupling. Knitted wire mesh structures offer useful surface area, flexibility, and mechanical resilience. They are commonly specified for process columns, gas and air systems, automotive assemblies, chemical equipment, food and beverage systems, and other machinery operating under demanding conditions.

Knitted wire mesh column packing is a structured material installed in separation columns to improve contact between rising vapour and descending liquid. Its crimped, layered construction creates high surface area and capillary action while maintaining a low pressure drop. This combination supports efficient mass transfer and more uniform fluid distribution. Packing can be supplied in suitable metals or alloys and formed for different column configurations.

Compressed wire mesh gaskets are made by compacting knitted mesh into a dense, uniform component. The resulting structure conforms to mating surfaces while retaining strength, resilience, and controlled flow characteristics. Depending on its design, a compressed mesh element can act as a seal, spacer, filter, vibration absorber, or separation ring. Material, density, thickness, and geometry are selected to suit the operating environment.

Gemini Wiremesh can manufacture knitted mesh components in stainless steel, copper, and other alloys selected for the application. Stainless steel is often chosen for strength, heat tolerance, and corrosion resistance. Copper-based options can suit specific conductivity or corrosion-resistance needs. The best material depends on process media, temperature, pressure, contamination risk, mechanical loads, and any compatibility requirements within the equipment.

Yes. Customization can cover ring, rectangular, and other required shapes, as well as diameter, thickness, mesh grade, wire diameter, density, porosity, and material. Gemini Wiremesh also supplies knitted mesh in rolls or cut-to-size formats for customers producing their own components. Sharing drawings, tolerances, operating conditions, and intended function helps establish a practical, performance-focused specification.

A useful specification includes the component drawing or target dimensions, intended function, process media, operating temperature and pressure, required material, desired filtration or flow characteristics, and any installation constraints. For gaskets or sealing rings, include mating-surface details and compression conditions. For column packing, column dimensions and separation requirements are especially important. These details guide material and mesh-structure selection.

Mesh density influences void volume, mechanical stiffness, filtration behavior, pressure drop, and liquid-holding capacity. A more open structure generally supports easier flow, while denser compression can increase contact area, retention, and sealing or damping characteristics. The appropriate density is determined by the component’s intended duty rather than a single universal standard. Gemini Wiremesh can tailor density for application-specific performance objectives.

Gemini Wiremesh operates under ISO 9001:2015 certified quality management standards. Consistency begins with selecting the specified material and continues through controlled knitting, forming, compression, and dimensional review. For custom orders, clear drawings and performance requirements help align the finished component with the intended application. Customers can also discuss relevant inspection, packaging, and documentation requirements during the specification stage.
