Filters and Fabricated Parts Made of Metal Wire Cloth

Customised solutions from a single source.

Whether in a simple part or a complex component - metal woven wire cloth is used everywhere in industry, research, the building trade and many aspects of everyday life. From flow filters in water taps to precision filter elements in space craft, woven wire cloth fulfils a variety of requirements and is fundamental to the area of application.

The material, shape and function are closely interrelated in filters and fabricated components made from woven metal wire. Based on the experience in the technology of wire weaving for more than 125 years Haver & Boecker produces metal woven wire cloth made of steel, stainless steel alloys, and special materials such as titanium, Hastelloy, silver, non-ferrous metals, aluminium, phosphor-bronze, brass, copper, nickel or MONEL. From these the company conceptualises, designs and produces, among other things, filters and fabricated parts for automotive, aerospace and aviation, chemicals, electrical engineering, medicine, water filtration, household appliances and food industry, plastics processing as well as machinery.

Subsequent processing takes place using the most up-to-date systems and machine technology for production processes, that enable not only standard solutions but also are developed for new applications and developments. These include new weave types, automation solutions, and conceptualising the optimum production and testing process. In addition to drawings, the special machine and tooling design of Haver & Boecker delivers CAM data to the CNC machine tools, e.g. for turning, milling and electrical discharge machining of classic stamping and deep drawing tools - and includes fully automatic special machines and injection moulding tools for filter production. So customised solutions for the above-mentioned industries can be realised from a single source - from the manufacture of metal wire cloth and further processing up to product packaging: for efficient production processes, secure functionality and optimal product quality.

 

Precise filter mesh for an efficient filtration 

Filter media made of wire mesh covers an extremely broad range, from ultra-fine micron structures up to coarse structures. The geometric filter structure is completely uniform throughout the entire area when compared to fibre-based filter materials made of paper, plastic or metal. Due to the metallic material used, wire mesh filters have high mechanical strength, good temperature resistance, wettability and are extremely resistant to chemical and physical influences.

Pore sizes (and hence material flow-through properties) can be precisely defined. Mathematical equations were developed by Haver & Boecker in collaboration with the University of Stuttgart and confirmed experimentally by the glass-bead test and air flow measurements. These calculation methods make it possible to determine new filter meshes according to the requirements of a specific application in advance without the need for exhaustive measuring methods.
