Reconditioning dies Eder Engineering is a specialist in the field of advanced die processing technology and equipment, and is a global supplier and advisor to the international wire and cable industry in more than 80 countries.

The rate at which natural and poly- crystalline diamond (PCD) dies need to be reconditioned and properly admini- strated is increasing, as more wire and cable manufacturers use higher speed multi-wire drawing machines, some offering up to 47 lines. However, these machines need growing numbers of expensive PCD wire drawing dies in each line simultaneously, wearing them out relatively quickly. They often have to be queued for recon- ditioning at die workshops, where skilled operators or suitable die reconditioning machines might be in short supply. To solve these problems, Eder-Austria has designed intelligent but easy-to-operate machines to handle the increasingly less available human skills in die tool maintenance, and offering the necessary

Its solutions for processing and re- conditioning larger quantities of ND/PCD multi-wire dies in modern workshops include single equipment to upgrade existing installations; complete die-tool reconditioning workshops; and turnkey die-tool production lines, with the hardware and software. According to Eder Engineering, worn- out drawing dies are assets that should be regularly reconditioned. Only die-tools that are in perfect condition can produce high-quality wires. Good maintenance of drawing die-tools can boost overall productivity and provide a quick return on investment.

Instant “live” pictures of wire imperfections Sensoptic is a Swiss company, established in 1998, that designs and manufactures fault detection equipment for continuous monitoring of bare and coated wires, fine cables, monofilaments, multifilament and optical fibres. detection and visualisation of micro- metric defects of fine wires and filaments running at high line speeds. It is particularly suited to quality control of round and flat magnet wires in production machines as well as in laboratory winding stations. When the size of a fault exceeds the defined threshold criterion, it visualises its shape in a graph and displays it photographically with high image quality.

Each fault is defined with a timestamp, its position, the maximum fault size, fault length and line speed. All values are stored in a table and saved in an Excel-compatible file. Dedicated software continuously displays statistical analysis of the detected faults. Sensoptic SA www.sensoptic.ch

The Sensystem turnkey solutions for quality inspection of multi-line production machines that include proprietary optical sensors, electronic controllers and user-friendly software packages. Sensoptic Vision is claimed to be the first instrument that allows real-time company supplies

The new instrument, which was designed and developed in cooperation with wire producers to match their requirements, captures high-resolution pictures of punctual surface imperfections and short diameter irregularities such as lumps, neck-downs, blisters and coating drop-outs.

Dosing and mixing Woywod Kunststoffmaschinen has been producing and marketing Plasticolor products for more than 40 years. The range includes single dosing units, double dosing systems, volumetric and gravimetric mixing stations, gravimetric throughput measurement systems, hop- per loaders and drying equipment (dry air and desiccant dryers). ▼

integrated into the mixing station concept, to ensure reproducible production over the entire speed range of the extruders. There are several types of dosing units for various output ranges. These are combined with different neckpieces,

weighing hoppers, storage hoppers and individual controls. Several series of dosing units have been modified to meet current safety requirements. Brushless motors and matching controls have been introduced, as well as a self-cleaning dosing station. Customers of the Plasticolor product range include operators in plastic processing, injection moulding, film and flat sheet extrusion, and the cable and pipe manufacturing industries.
