Cleaning of extrusion screws - cause of productivity and quality loss. Today, pressure on cost reduction in day to day production becomes high and higher and leaders of production sections very often hear the question – what can we do, to reduce cost and increase productivity further? Raw material supplies have been squeezed already as far as possible and man power has been reduced to a certain limit. One area however is commonly considered as not so important or as a fact which cannot be changed. That is cleaning of extrusion systems and line stoppages or increased scrap due to unqualified cleaning.

One of our customers has calculated, that the loss figure can be as high as 27% in productive time and up to 20% in scrap. In addition to these impressive figures, improper cleaning methods (mechanical hand tool cleaning, high temperature flame cleaning, chemical cleaning) are damaging screws, cross heads and tooling. The answer to these problems is non destructive cleaning by means of air and a non corrosive and non abrasive blasting media as offered by us since more than 15 years, the Triboclean system. More than 300 systems sold worldwide are best answer to the question – who is using it. (a reference list is available on request) On the following pages, you will find an explanation, how the system works and what happens during the process.

A typical barrier type screw, as used for modern filled, low smoke, halogen free compounds

The screw looks almost clean and ready for the next run. Cleaning was undertaken by means of “conventional” methods. Checking the surface however under the microscope, you will find, that it does not look so good. Cablexpert´s e.U., FN 331969 Peter Roseggerstrasse 21 3433 Königstetten Austria
