KnitMesh products are used extensively within the transport industry. Whether for filtration, vibration control, anti-vandal protection or a range of other uses, our knitted wire mesh offers a unique combination of high-strength and low-weight that makes it the preferred choice for a variety of transport applications.
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 made of wire, comprising continuous lengths of filament of almost any material type, formed into interlocking loops. This unique structure produces a material that, whilst being highly flexible, has the tensile strength characteristics of the component filament material. Applications include very fine flexible mesh nets such as those used in animal enclosures that can withstand snow loading of >250kg per m2.
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.
High Surface Area
Knitted mesh can be processed from a wide variety of materials to produce densely packed components with high surface area per unit weight or volume. Surface areas of >30,000 m2 per m3 of compressed material can be achieved which is equivalent to >5 m2 per kg of stainless steel. In cost terms this feature of knitted mesh compares very favourably to other technologies and is utilised in applications such as catalyst substrates or where rapid heat transfer from a fluid is required.
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.
Applications by transport operators include:
Mesh components for engine breather and braking systems
Anti-slash composite fabric applications for use as protection against vandalism in mass transit passenger seating or illegal entry into curtain-sider (Tautliner) trucks
Flexible gangway connections for railway coaches
Multi-filament construction for extra strength
Combination (co-knit) construction for added strength e.g. Kevlar yarn
Anti-vibration and acoustic control components for use in mass transit systems e.g. floating floors and seat support in railway and subway rolling stock
Filters for hot air balloon gas burners
It can be seen that KnitMesh products travel far and wide – by air, road, rail and sea!
Features Of Knitted Mesh
Knitted structure captures knife blades, helping to reduce significant damage
Available on cardboard cores for easy further processing, in mesh widths from up to 1 metre wide as a double layer sock or 2 metres wide as a single layer
Saves money by reducing damage from vandalism to passenger seating and railway coach flexible gangway connections or by protecting curtain-siders to reduce repair bills and theft
Versatile material type and combination choices, for example multi-filaments for extra strength or co-knitting materials together such as stainless steel wire with Kevlar yarn
Mesh components can be used for engine and braking system breathers
Suitable for anti-vibration and acoustic control components for mass transit, for example floating floors and seat supports in railway and subway rolling stock
Extremely light weight and designed to capture moisture
Double filament knitted wire mesh is used for anti-slash protection in heavy goods vehicle curtain siders and protect against theft and illegal entry.
Double filament knitted wire mesh is used for anti-vandal protection in mass transit seating composites and can have multi-filaments for extra strength or be combined with other materials such as Kevlar yarn.
