Résumé : |
Once again, the K 2019 in Düsseldorf, Germany, lived up to its claim to be the leading trade show for plastics technology. At least in the field of injection molding, there were exciting global innovations to see – if you looked closely. One reason why the innovations were not so obvious could be that injection molding technology has reached such an advanced stage of development that details and relatively minor changes have a large effect. Another is that many of the leaps in development are taking place on a virtual level. |
