Success at wire 2006 in Düsseldorf, Germany, has seen Extrudex receive a large number of enquiries for extruders and follow-up equipment for the production of miniature cables. And several successful sales of mini extrusion systems has been in the medical technology industry. Due to ever complex systems in the medical and automation fields, data and power supplies need to be securely provided in the smallest space available. This means conductor diameters in the range of AWG 25 – AWG 50 and wall thicknesses in the micron range, eg 20µ. The required tolerances correspond to these and keeping to them is a must. The Extrudex extruders with screw diameters of 12 and 15mm have a conveying length of 25 D. Minimum melt stopovers prevent excessive demands and reduce any quality loss, such as inclusions or burns. Additionally, this keeps rejects to a minimum. Output is between 50 and 3.500 g/h depending on the material and tools used. The unit is driven by a compact, maintenance-free AC motor. The conveying screw range is designed for standard pellet shapes and can be optimised according to the materials.
