Electronics & Telecoms

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 (EMC) Directive 2014/30/EU.

Flexible & Malleable

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.
High Resilience icon

High Resilience

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.
EMC/RFI Screening icon

EMC/RFI Screening

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.
Harsh Environments icon

Harsh Environments

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 icon

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.
Environmentally Friendly icon

Environmentally Friendly

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.

We offer a wide range of high resilience knitted mesh EMC shielding products and will use our extensive manufacturing and product testing capabilities to rapidly prototype the products and solutions your innovations and processes require.

Knitex® All-Metal Compressed Gaskets

Our Knitex® All-Metal Compressed Gaskets shield applications in microwave ovens, CCTV, wave-guides, connectors and shaft seals from EMI.

Due to their all-metal construction, they are extremely efficient heat conductors and are resilient to high temperatures and shock absorption, rendering them suitable in even the most severe environmental conditions.

  • Available in a range of materials to suit requirements
  • Can be supplied as a ring, rectangle or other special shapes
  • Available in a range of sizes and densities

Knitex® Shielding Tape Gaskets

Our Knitex® Shielding Tapes offer ultimate protection against microwave, RFI & EMI interference (Radio Frequency Interference & Electro-Magnetic Interference).
Typically used within electrical and electronic cable assemblies, cable jointings, grounding, static discharge and within connecter assemblies.

  • Available in a range of materials to suit requirements
  • Can be supplied with a crimp for greater thickness
  • Available in widths from 6mm – 200mm wide

Knitex® Mesh Over Elastomer Core Gaskets

Our Knitex® Mesh Over Elastomer Core Gaskets are used extensively on electronic enclosures where there is a seam unevenness and low closure forces are required.

A single cover of knitted mesh is sufficient where only a moderate degree of shielding effectiveness is required – a double cover is recommended for higher levels of attenuation.

  • Available in a range of materials to suit requirements
  • Supplied with a Neoprene Sponge, Silicone Sponge, Silicone Tube or EPDM

Features and Benefits

  • Available in many different formats and profiles including, round, rectangular, ‘P’ section and double core with fin
  • Suitable for groove mounting, glueing, riveting, spot welding and soldering
  • Will operate at extremely high temperatures
  • Manufactured in a wide range of metals
  • Constructed from knitted wire mesh with numerous interlocked loops for high resilience
  • Available in metal and elastomer combinations for weather, environmental or pressure sealing
