Haver & Boecker OHG products

Warp and weft wires are of almost the same diameter.

Rectangular apertures: can be fabricated as oblong and broad meshes.

Technical woven wire cloth manufactured by Haver & Boecker is used for screening and filtration in almost every industrial sector: chemical, plastic, automobile, aviation, aerospace, electronics, industrial screening (mining and quarrying), test sieving, food processing industry and a host of other applications. In addition to its technical properties, Haver & Boecker woven wire cloth has a high aesthetic appeal for architectural and and design projects.

HAVER PLYMESH are woven wire cloth laminated panels. The individual wire cloth layers are bonded together by means of a special manufacturing process. PLYMESH is a porous, sheet metal like medium for fluidization and filtration applications. These laminated panels can be made up of woven wire cloth layers with square openings or MINIMESH filter cloth specifications or a combination of both types.

Precision Pores for the Highest Demands in Industrial Filtration. MINIMESH® Metal Filter Cloth from HAVER & BOECKER has been used as filtration media for over 100 years. Already in 1954 it was used in space within NASA’s aviation and aerospace programme. With their once previously impossible-to-achieve filter fineness, MINIMESH filter cloths enabled smoothly functioning control systems and engine units. The wire mesh was used in all Apollo flights, proved itself in the Space Shuttle, and in civil aviation up to today.

High Performance Metal Filter Cloth in a New Dimension. Where conventional filter cloths have reached their limits, MINIMESH RPD HIFLO-S opens up new dimensions for filtration. Using new weaving technology developed by Haver & Boecker, a three-dimensional pore geometry is created that offers filtration properties that have not yet been attainable with all previous woven metal filter media. These properties set new standards and make industrial filtration processes quicker, safer and more efficient.

With the HAVER TRICKLE TESTER, a bulk material`s capability to trickle can be optimally determined. The time it takes for the material to flow though a hopper is measured. Depending on the product properties, various hoppers with different diameters may be used. The quality of a product can be checked using this approach, thus allowing detection of deviations. Differences between fresh and stored products, batch changes, different treatments, coatings or material admixtures can be qualified. Moreover, demixing effects can be determined.

With the Haver Deaeration Tester, filling and air escape characteristics of powder-type, micro-granular, gritty and mixed products can be determined. In addition, the through-flow resistance of a product is also measured. Using a pre-defined air pressure, the air flow in a feed line or a silo can be simulated.
