Save on dies with Eder

the conical die-portions is available, while the other model TCLD-B-CNC serves for a precise processing of the cylindrical bearing. If required, both TCLD machines can combine to operate in an in-line mode, using an intelligent robot connection.

Eder Engineering has a leading position in advanced diamond and PCD die working equipment, offering universal flexibility and application, a high degree of automation – even on standard units – and highest possible efficiency, particularly in machinery for the reconditioning and production of diamond and PCD dies. While PCD dies play a major role in the non-ferrous wire drawing industry, the majority of ferrous wire is drawn using tungsten carbide (TC) drawing die tools. TC dies need totally different working methods and machines for their repair. For the average TC die user, dealing with frequent changes in die-bore diameters and a wide size application range, Eder has developed the semi-automatic ETC-1/HF. This unit is said to grind and polish both the conical and cylindrical die bore sections “in record time.” Wire drawing plants dealing with tungsten carbide dies in near identical bore-sizes and/or similar stages of wear, however, are more efficient using fully automatic equipment. In cooperation with AGIR-France, Eder offers completely automatic machines for all usual sizes of round tungsten carbide wire drawing dies. All operations are managed by an OPLC combined with an intelligent program. According to the type of the TC die-nib material to be processed and the kind of operation chosen, the OPLC allows program adjustment to optimise the production or reconditioning of TC dies within the indicated work range. For processing TC dies of 1mm to 6.5mm diameter, model TCLD-C-CNC for producing or reconditioning of Eurotek srl offers a comprehensive range of manual and fixed cross- heads including single layer, co-extrusion, skin-foam-skin, in Hastelloy for fluoro-polymers (FEP, Teflon, Tefzel), flat and ribbon cables, co-extrusion with different temperatures, thermo-regulated for silicone rubber, manual and pneu- matic by-pass modules and spare parts.

Steel cord wire producers and other special plants use many tungsten carbide dies with small bore-sizes. For these customers Eder-Austria offers the high precision, easy to use TCSD-CB-CNC that can work both the conical die-portions and the cylindrical bearing part in a diameter range between 0.1mm to 1.5mm. Precisely manufactured and well maintained wire drawing dies, whether diamond/PCD or TC, produce longer uninterrupted runs, excellent wire surface quality and improved performance, leading to considerably higher output. Any necessary change of a die set in wire drawing machines will usually cause a down time of between 20 to 40 minutes. If die life can be increased by 10%, this results in a 10% increase in productivity. Eder Engineering – Austria Fax : +43 1 367 494949
