Dinxperlo has an international reputation for its expertise and high-quality specialist woven wire products. Dinxperlo produces woven wire in all mesh sizes, from extremely coarse to ultrafine, and in every weavable metal. The result is a wide variety of woven wire products, making it impossible to keep stocks of every type. We keep stocks of the ones that are most in demand.
When weaving mesh, the warp and weft wires cross in an alternately pattern. There are a number of weaves for woven wire products. The simplest pattern is known in English as ‘plain weave’ because of its simplicity: each wire passes in turn under and over another wire, the wire diameters are usually the same in both directions and the mesh apertures are either square or rectangular. Dinxperlo produces woven wire with mesh sizes from 5 microns to 25mm and wire diameters from 20 microns to 4.0mm. Plain weave mesh has very good sieving properties.
A third type of weave is known as ‘Dutch weave’: there is a plain Dutch weave and a twilled Dutch weave. For more information on Dutch weave see the section on Dutch Weave Filter Cloth.
Dinxperlo has a large department with machines designed specially to produce ultrafine woven wire.
The stock woven wire products are made from wire of the following materials in particular:
• Uncoated iron
• Uncoated iron (product subsequently hot dip galvanized)
• Galvanized iron
• Brass
• Bronze
• Monel
• Spring steel
• Aluminium
• Stainless steel
• Heat-proof steel
• Galfan
Special runs can be supplied in the materials required; a few examples:
• Polypropylene
• Polyester
• Copper
• Inconel
• Incoloy
• Tungsten
Some materials can be specially treated to improve quality. The treatments available at Dinxperlo include:
Galvanising: improvements resulting from galvanising include:
• It protects corrodible materials (e.g. iron) against atmospheric corrosion; the most common product is galvanized iron mesh.
• It reinforces the mesh by creating a kind of ‘weld’ at the intersections of the wires.
Epoxy-coating: applying a coating of epoxy material:
• This protects the woven wire product against atmospheric corrosion and above all against the effects of additives in hydraulic fluids.
• It brightens up the appearance with different colours.
• It reinforces the mesh by creating a kind of ‘weld’ at the intersections of the wires.
Cleaning: washing or ultrasonic cleaning of products:
• Used as pre-treatment before e.g. epoxy-coating
• To remove contaminants from products, e.g. for filtration applications
• Degreasing
Annealing: heating the material until it starts to glow:
• This removes the hardness in the product caused by the weaving process, making the material more deformable.
