Knitted Wire Technologies

Knit wire or woven wire can be produced in a variety of stitch patterns and densities. Additionally, metal meshes can also be crimped in a diagonal or herringbone pattern. This allows the free volume and specific surface area of filters to be adjusted to suit pressure drop limitations and efficiency requirements. Knit wires and other filaments can be flattened to increase specific surface area and efficiency.

Any material that can be drawn or spun into filament form can be used to produce a knitted mesh structure for use in the manufacture of products including:

• Stainless steel — of grades 304L, 316L, 321, 310 and 310S are typical for long life, temperature and corrosion resistance
• Galvanised steel — for low-cost, less demanding applications
• Aluminium — for numerous aerospace, military and nuclear applications
• Copper — in compressed form, for breathers and filters
• Nickel and copper nickel alloys — for marine or saline environments
• Polypropylene — lightweight, inexpensive and corrosion resistant
• Hostaflon* and Teflon FEP+ — fluoro polymers for excellent performance in acidic environments
• Glass wool and Teflon+ — for the filtration of very fine particles
• Plastic/multi-filaments — for high-efficiency applications and noise reduction

We test our knit wire extensively, for the extremes of temperature, pressure, compression and corrosion, to make sure that the products you purchase are ideal for the conditions you have specified. Research and development uses both cutting edge materials and current materials in innovative ways to create the best products on the market and the best products to serve you in the future.
