Modern electronic technologies require security and protection against electromagnetic interference (EMI) and radio frequency interference (RFI). Manufacturers of products creating EMI and RFI need to comply with the Electromagnetic Compatibility Directive (EMC 2004/108/EC).
The flexibility (ability to be bent without breaking) and malleability (the ability to withstand plastic deformation without fracture) of our products can be designed according to customer needs. Through a careful selection of materials, mesh structure, and tooling design, we can produce mesh components in an almost limitless range of shapes including sheets (blankets), highly flexible hollow mesh tubes, and 3-dimensional rigid structures such as prisms, cubes, spheres and doughnuts, etc.
Resilience can be defined as the ability of a material to absorb energy when deformed and to release that energy on unloading. The feature is particularly beneficial in applications such as seals (often incorporating resilient cores), gaskets and vibration isolators for use in both high and low temperature environments. Our engineers can work with customers to select the materials and manufacturing methods required to configure a product that will perform to the most exacting specifications.
Knitted mesh is used to form an enclosure that acts as Faraday Cage to block electromagnetic fields. This phenomenon is used to screen (protect) sensitive electronic equipment from external radio frequency interference (RFI) and enhance electromagnetic compatibility (EMC). Faraday Cages are also used to enclose devices that produce RFI, such as radio transmitters, to prevent their radio waves from interfering with nearby electronic equipment. These knitted mesh screens can be produced from a wide range of materials including tin-plated copper or copper-plated steel and formed as cooling vents, flexible cable jointing ‘bandages’, and resilient joint seals with elastomer cores for inspection hatches or doors and windows, etc.
Materials can be selected and processed, in any of a huge number of possible variants, to produce knitted mesh components that will withstand the conditions experienced in the most arduous of operational environments. Corrosion resistance and fatigue tests at up to 1,000°C can be conducted on-site with products typically being used in aerospace, automotive, refractory, cryogenic and marine environments.
Encapsulates & Protects
Knitted mesh can be used to encapsulate and protect fragile materials such as the ceramic bricks used in catalyst applications. We also specialise in the ‘over-knitting’ of special materials such as graphite or mica, that are produced to deliver properties against specific customer requirements such as fluid seals or self-lubricating gaskets.
Our customers are almost invariably seeking to reduce costs and/or enhance their products or process efficiencies. The added benefit of these partnerships is that all of our products are non-toxic and contribute to the 3Rs of the circular economy: Reduce, Re-use and Recycle, which fits perfectly with our own strapline of the 4 Ps: Protecting people, property and our planet.
With over 60 years expertise in Electromagnetic Compatibility (EMC) shielding, we design, develop and manufacture products that meet the suppression needs of numerous organisations across the electronics, aerospace, military, commercial, telecommunications, medical, test equipment and enclosure industries.

All of today’s sophisticated methods of telecommunications require protection against radio frequency interference (RFI) and electromagnetic interference (EMI).
Our knitted wire mesh is used extensively in many different formats to protect all types of telecommunications, including, phone and computer networks, satellite systems, TV and radio, etc.
Our knitted mesh shielding gaskets are used on a diverse range of equipment ranging from microwave oven components to cabinets and enclosures for electronic equipment.
Today's increasingly sensitive electronic control technologies can require shielding against electromagnetic interference (EMI).
At the same time, manufacturers of products creating EMI and radio interference need to comply with the electromagnetic compatibility (EMC) directive.
Our specially developed insulated wire mesh is used as a security envelope to encase electronic devices that process secure data. Please contact us for more information.
Applied like a bandage for EMC integrity, grounding and static discharge around cable joints & connections, our knitted mesh tape is a flexible, light-weight but strong alternative to other more fragile tapes.
KnitMesh Technologies supply EMC shielding tape as a Pan Mesh approved manufacturer for the Eurofighter project.
