Large round and shaped wire drawing dies

In the late 1990s, Paramount Die Company incorporated pressure dies and draw dies in a single holder – the ParaLoc pressure system. The company says that this technology has enabled wire producers to increase productivity, improve finished wire quality and grow their businesses. In addition to dies for fine wire drawing in the size range of 5.5 to 0.5mm (0.218" to 0.02"), Paramount produces and sells a full line of wire drawing tooling, including large cased dies with cases up to 300mm (12") in diameter. It is also a major supplier of shaped dies to the global wire drawing industry, and makes other carbide tools used in the wire drawing process, such as shaving dies for high carbon valve spring wire, stainless and non-ferrous applications. Paramount has incorporated the scientific approach used in the development of the ParaLoc holders and its wire drawing dies into the development of large dies, shape dies and shaving dies, aiming to provide improved productivity, higher quality and scrap avoidance. This approach is followed through the design, production, inspection and application of Paramount dies. Paramount Die Company www.paradie.com High-speed spooler improves output at Asta DEM has supplied to Asta of Austria a spooler designed for operation at 1,200m/min, with special features to provide perfect layer winding of copper profiles, including some as small as 1.5 x 0.5mm. The new unit has replaced a spooler installed on a non-DEM line. New software and hardware are part of the DEM package, and the replacement and industrial start-up took place within just one week from delivery. The traverse coiling achieved with the new spooler plays a key role in the unwinding during downstream enamelling operations, providing a continuous and uniform unspooling speed and contributing to a regular coating along the conductor length.
