continuous casting technology. The sealed lid with enclosed atmosphere allows accurate and consistent composition control of alloys containing reactive and volatile elements, for example Cr, Zr, Ti and Mg, and eliminates the need for graphite ake melt cover.
diamond (PCD) die blanks of its own product brand MANT® (www.mant. com). The unique development is a thermostable PCD blank with a conical tungsten carbide ring size D-15. The MANT MTD-15-005-TS is meant for high-duty drawing of hard materials, especially for welding wire and stainless steel drawing in the range of 0.8-1.5mm wire diameter.

During high- temperature sintering process the PCD is “baked” from synthetic diamond powder of an extremely narrow 5-micron grain size together with catalyst metals like cobalt. This agent e ects the bridging of the diamond crystals and forms a PCD body like a dense and brittle sponge. In the “pores” remains a content of some 6-8 per cent of cobalt. Having di erent coe cients of thermal expansion, the metal cracks the diamond bridges at higher temperatures leading to an earlier breakage of the die. Therefore “normal” PCD blanks are limited to a process temperature while casing and drawing of about 650°C. With leaching in hot acid over several weeks the metal content in the PCD is reduced to traces. This gives no expansion of di erent materials at higher temperatures because only diamond is left. Afterwards the PCD is cut by laser and then polished into its nal conical form to be set under pressure into a conical ring of tungsten carbide. The conical tting gives a better resistance to axial forces during the drawing process. The MANT MTD-15-005 is then set into the stainless steel casing at Redies by application of Ni-alloy sintering material up to 1,050°C, resulting in a tough “corset” around it. The further laser drilling, ultrasonic pro ling and polishing is done the same as with a “normal”wire drawing die.

Reber Systematic, better known as Resy, is a Germany-based company that has been providing the wire and cable industry with a complete range of ltration systems for coolants and lubricants for more than 40 years.
Ravni Technologies Stand: 10B12
Ravni Technologies produces the e cient and powerful wire straightening and cutting machines MDC30 (3 to 10mm) and MDC50 (5 to 14mm). A new servo-cutting device has also been successfully integrated on the range.
Resy compact band lter

Pure ltration of coolants and lubricants will give the e ect of higher productivity due to fewer wire breaks, less down time, lower wear of the dies and much better surface quality of the wires. To achieve these goals, Resy develops and builds single lters, integrated ltration systems or complete central ltration systems for emulsion and oils.

All machine functions can be found on the user-friendly control panel, which displays the di erent stages of the production process. As with all Ravni models, the machines are tted with a fast tool changer. The preset straightening tools saves time and waste at every diameter change. The company’s production programme also includes: • Tube cut-o machines • Chamfering machines
