Extrusion Asia Edition 1-2019

screw extruder. No matter which high-peformance solution is used, they mean moderate capital expenditure, along with high output, reduced energy consumption, ease of operation and minimised need for maintenance.

The complex line is characterised by an elaborated setup, which is combining durable machine design, proven components and the latest state-of-the-art technology with a maximum of ope- rator convenience and production efficiency. With the newly introduced automation system in combination with a powerful data logging system it is giving maximum traceability and qua- lity control to the end user – making the machine ready for the challenge of industry 4.0. MDO units for greater flexibility and excellent film results Based on decades of experience SML has designed a new mo- no-axial direction orientation unit which offers greater flexibili- ty in terms of processing a huge variety of different film types and structures in large film widths. Its main advantage lies in its ability to control film properties through the inline variation of the stretching gap between 70 and 350mm using a servomo- tor. This is significant because the best PP and PE film characte- ristics result with a shorter gap, while a longer gap is required when stretching PET film. Excellent results are guaranteed in terms of improved visual qualities, achieved tenacity, increased barrier properties and reduced film thickness. And not to forget the breathability for hygiene applications. In short, stretching using SML’s innovative MDO technology means higher production speeds and output in combination with process flexibility and excellent film properties. PET sheet lines and the choice of three extrusion concepts SML’s third focus is on its extrusion concepts for PET/rPET sheet production. Due to SMLs vast experience in PET extrusion, SML assist its customers in the selection of the best extrusion system for their application and available feedstock: single-screw ex- trusion with pre-drying, recycling extruder or conical twin- SML的 MDO单元大大提高了生产效率 SMLs MDO unit boosts productivity
