HAVER & BOECKER OHG Drahtweberei und Maschinenfabrik

Customised solutions from one source
Whether in the form of precut sections or as 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 the precision filter elements in spacecraft, woven wire cloth fulfils a variety of requirements and is fundamental to the areas of application.
Material, shape, and function are closely interrelated in filters and fabricated parts made from woven metal wire. Based on more than 125 years of experience in the field of wire weaving technology, Haver & Boecker produce metal woven mesh made of steel and stainless steel alloys, and special materials such as titanium, Hastelloy or silver, or non-ferrous metals such as aluminium, phosphor-bronze, brass, copper, nickel or MONEL. From this metal woven mesh, the company designs and manufactures a wide range of products, for example filters and fabricated parts for the automotive industry, aviation and aerospace sector, for the chemical, electronics, medical technology, water filtration, domestic appliances and food industries, for plastic processing and machine engineering applications.
Subsequent processing takes place using state-of-the-art systems and machines technology. Our manufacturing processes not only allow standard solutions but also individually customized applications, such as the development of new products, automation solutions, and the design of optimised manufacturing and test processes. Haver & Boecker have their own tool shop which designs special machines and tools and supplies not only the drawings but also the CAM data for the CNC machine tools for lathing, milling and electrical discharge machining. In addition to conventional stamping and deep-drawing tools, Haver & Boecker build fully automated special machines and plastic injection moulding tools. This gives the customer the benefit of a tailored single-source solution, from the manufacture of the woven wire cloth over further processing up to the packaged product. This ensures efficient manufacturing processes, reliable function and optimum product quality, and allows for the special designs required in the above-named sectors.
Precise filter mesh for efficient filtration
Filter media made of woven wire cloth are offered in an extremely broad range, from ultra-fine micron structures up to coarse structures. In contrast to the structures of fibre mats made of paper, plastic or metal fibres, the geometry and thus the filter structure of woven wire cloth is perfectly uniform over the entire filter surface. Made of metal materials, wire mesh has a high mechanical strength, temperature resistance, wettability, and it is extremely resistant to chemicals and physical influences.
Pore size and thus the material and flow properties can be precisely defined. In cooperation with Stuttgart University, Haver & Boecker developed mathematical equations and validated them by glass bead tests and air flow measurements. These calculation processes now provide for optimum dimensioning of the new filter mesh already before the production in accordance with the customer's individual requirements, eliminating the need for time-consuming and expensive tests.

MODERN SCREENING TECHNOLOGY WITH A FUTURE.

Based on more than 125 years of experience in the manufacture of woven wire, Haver & Boecker has continuously developed screening technology. In addition to woven wire from our own production, which is made with the classic warp and weft, we offer in cooperation with our subsidiary companies a comprehensive range of complete systems that extends to screening machines. We provide everything surrounding screening technology worldwide.

Your partner for every screening process.
Haver & Boecker offers industrial screens that fit precisely to the specific requirements at hand when it comes to material, processing, and type of weft. The spectrum encompasses solutions for all types of screening machines and applications: classic screen decks made of stainless steel and special self-cleaning screen cloth. Whatever screen type you decide to use, premium quality materials and meticulous processing guarantee optimum function, maximum stability, and long lifetimes.

Our product range encompasses screening media for every kind of screening machine and offers mesh sizes from 0.025 mm to over 100 mm. For materials we offer various austenites and stainless steels in addition to HAVER NIA® spring steel. They not only provide optimum function, but also assure maximum stability and long lifetimes. We deliver all screen products as rolls, cut sections or fully manufactured as desired with a number of and tensioning profiles to select from, pre-tensioned on screen frames, and according to ISO 9044 and ISO 14 315.

-Standard square and rectangular mesh woven wire cloth
-Special rectangular TON-CAP and EGLA-MAX mesh cloth
-Tensioning systems in all variants for all screening machines
-Pre-tensioned screen frames and tensioning service
-Ultrasound screen decks
-Highly efficient FLEX-MAT screen decks
-Haver DMS and Haver UMD small screening machines

THE PROCESS GOT TO BE RIGHT
Whether using traditional or photo-optical particle analysis – the process for measuring bulk materials should be as simple and yet accurate as possible.
At this year’s Powtech in Nuremberg, HAVER & BOECKER presents everything about process optimization in particle analysis. Sample preparation, measuring, weighing, analyzing are simply an integral part of particle analysis. This applies, both, to the classic screen analysis with sieve set and test sieve shaker as well as computer-assisted particle analysis of size and shape of dry, non-agglomerating bulk materials particles.
The HAVER particle analysis offers its customers a process chain all of a piece. Generating reproducible sieving results is important with classic sieve analysis. Thanks to the automatic sieve identification and data acquisition from the balance, the analyses are evaluated quickly and reliably with the HAVER CSA software.
With photo-optical particle measuring devices, the HAVER CPA 2-1 can be employed online for continuous quality control in the running process. It is continuously in stand-by mode ready for measuring and performs regular sampling for analysis.
Using an auto-sampler promotes efficiency through automation. The consistent combination of dynamic optical particle measurement and automatic sample supply allows expanding the measuring capacity of a one-shift test lab by up to 24 automatic measurements.
Our team will be glad to demonstrate the options and diversity HAVER & BOECKER offers in the area of particle analysis. We look forward to your visit!
