Once again the Deutsche Kautschuk Gesellschaft e.V. (German Rubber Society) and the Deutsches Institut für Kautschuktechnologie e.V. (German Institute for Rubber Technology) organized the workshop “Mixing of Rubber Compounds” together with Harburg-Freudenberger Maschinenbau GmbH in Freudenberg.
Taking place for the seventeenth time from May 6th to May 8th, 2015, a total of 59 participants from 13 countries and 3 continents had the opportunity to test their theoretical and practical knowledge on the rubber mixing process.
The technical knowledge imparted could directly be practically implemented during a series of mixing trials carried out in the Technical Center of Harburg-Freudenberger Maschinenbau GmbH.
Three German and three international groups had to face a range of challenges in a mixed competition consisting of three trials on two different laboratory mixers (tangential mixer GK 4N and intermeshing mixer GK 5E). The aim was to produce a high-quality EPDM (German group) or SBR \ BR (international group) compound as fast as possible.
Employees of the Technical Center were on hand to ensure that the trials went smoothly and they supported the teams in creating the recipes and carrying out the trials. Also present were employees of MonTech to provide results of the analysis for evaluating the quality of the individual test samples.
With the theoretical knowledge learned, the participants were ready to improve their next attempt on mixing with the help of the analysis results and data measured on the mixer.
At the end of the seminar the winning teams received a very special prize: An envelope full of gummi bears…
