Knitted Wire Mesh A range of knitted wire mesh gaskets, providing a cost-effective solution to high shielding performance applications in the magnetic and electrical fields RFI/EMI and including EMP. Manufactured on a circular wire knitting machine using a single wire. The mono-filament interlocking-loop construction gives strength while allowing it to conform to almost any size or shape. The manufacturing process allows for an optional elastomer core to be included in to the product to aid compression. An additional environmental seal/carrier is also an option. It is available in a variety of combinations to suit many EMC and environmental sealing applications. Kemtron’s knitted wire mesh is available in 3 options 1. Solid Knitted Wire Mesh. 2. Elastomer cored knitted wire mesh. 3. Knitted wire mesh with an additional environmental seal. Production Capabilities Kemtron has developed its knitted wire mesh production facility and expertise in this area to enable it to produce RFI/EMI gaskets in a wide range of materials and in many different size configurations. Together with our extensive fabrication capabilities and large stocks of raw materials, we can manufacture knitted wire mesh gaskets to suit many applications. We offer a bespoke service, which can also produce economical gaskets, with good delivery times, in prototype quantities or for short, medium or large commercial production runs.

Knitted Wire Mesh Over an Elastomer Core Product Overview This product is a knitted wire mesh over an elastomer core such as neoprene or silicone cellular profile or tube. Usually this consists of 2 layers of knitting over the elastomer core but small sections 1.5mm diameter requiring only 1 layer. The knitted mesh is then formed into the selected profile making a continuous gasket strip which is flexible and compressible and which makes an excellent RFI/EMI/EMP gasket. Application In addition to making an excellent EMI/RFI/EMP shield between two metallic surfaces the choice of wire mesh...
