Due to the huge variety of different products Lenzing Plastics manufactures, the latter had high demands con- cerning the flexibility of different product widths, as well as the type of substrates and applied polymers. Equally de- manding were the requirements for very quick setup times between one production run and the next. To provide an example: The two extruder screws (135mm and 90mm in diameter) can be changed in the shortest time, thanks to a new quick-change-system which SML has developed especially for Lenzing Plastics. Generally, the line can be switched from the production of common polyolefins to special TPU applications in less than three hours. Thanks to an inline slitting unit featuring multiple knives, Lenzing Plastics can run several part bobbin rolls in finished widths on one winding shaft. This saves time and money since an additional production step via a slitter rewinder can be avoided. SML’s new SMILE operating interface in combination with the data generation and analysis tool BitWise en- sures the comfortable operation of this new coating line. The maximum reproducibility of specific formulations is a solid basis for effective quality control and constant pro- duction qualities. As a result of the close cooperation between the techni- cians from Lenzing Plastics and SML, both companies were able to benefit and to strengthen their leading position. As a result of the success of this project, there is a mutual commitment to forge ahead with further cooperation in the future.
