automated wire production

Meltech announces the DR-1000 for automated take-up

Weaving ideas from metal wires Haver & Boecker, Germany, began production of woven wire cloth in 1887, and today has production sites in Germany, UK, Belgium, USA and Canada. The company uses the latest pro- duction technology and equipment, as well as a sophisticated quality control, to provide wire cloth for any application, including screening and filtration in many industries: chemical, plastic, automobile, aeronautic, aero- space, electronic, industrial screening (mining and quarrying), test sieving, and food. Wires as thick as 16mm (0.63") diameter down to those of only 0.016mm (16 microns) are woven according to ISO 9044, using state- of-the-art machinery and a team of qualified experts. Haver woven metal wire cloth is also used for exterior and interior archi- tectural design applications, such as façades and ceilings.

Wire processing specialist, Meltech Engineering, has recently announced the MT-DR 1000, the latest addition to the DR series of automated dual reel take-up machines for continuous production of wire and cable. The MT-DR 1000 features a 1,000mm reel size with winding speeds up to 750metres per minute for data communications and LAN cables, general wiring and heat shrink and wire tubing applications.

Accurate winding control lies at the heart of the MT-DR 1000. Meltech’s control technology calculates the precise tensioning of the wire during winding. The control system also features a selection of manufacturer specific recipes, based on winding pitch settings, drum sizes and optimum layering patterns. In addition the take-up machine’s control system to give improved winding control, layering, and speed and length control at point of changeover. The MT-DR is a robust machine that can be readily integrated within an existing wire production line. The Meltech dual reel take-up machine is available in both semi and fully automated operation. The DR 1000 compliments Meltech’s approach to manufacturing silicone rubber coated, single and multi-core wires, and low-halogen jacketed cables. It offers a complete production line, yet requires less space than existing lines, and with higher production speeds. Traditional silicone rubber coating of wire has meant feeding the coated wire through salt baths or steam to provide the heat needed to cure the coating. Typically the baths can be up to 100 metres long, from which the wire emerges and is then dried. Meltech uses an infra-red oven to heat and cure the silicone rubber in a fraction of the time taken with salt baths. And at 12 metres, the oven is also significantly shorter, reducing the space needed for coating operations. In combination with Meltech’s automated pay-off and coiling machines, manufacturers can expect to achieve typical production speeds of up to 140 metres per minute.

Haver & Boecker meshes are available in many different patterns, each with its own characteristics in terms of strength, transparency, metal density, surface finish and optical effect. This results in an attractive, strong and manageable material. Haver architectural wire cloth has been used in internationally renowned architectural projects.
