MAS together with Caroda BV win PRSE “Recycling Machinery Innovation Award 2020”
Gel-less film recycling with Mas Technology by Caroda BV and MAS Maschinen-und Anlagenbau Schulz GmbH Plastics.
MAS proudly announce that together with Caroda BV Polymers have won the PRSE (Plastics Recycling Show Europe) 2020 award for “Recycling Machinery Innovation Award”. After being named as a finalist in January 2020, MAS fought off stiff competition from the likes of EREMA to win the coveted award at the Plastics Recycling Show Europe Virtual Event held between the 9th-11th December 2020.
The special design of conical co-rotation MAS extruder allows the use of a twin-screw extruder for film recycling under economic conditions. (without pre-densification or agglomeration prior to the extrusion process). The main distinctive feature of the MAS twin screw extruder is the conical design, which provides a big feeding opening and as a result a huge intake volume.
Due to the intake volume, it is possible to feed film fluff without pre-densification or agglomeration prior to the extrusion process. Flexible, exchangeable kneading elements ensure the right amount of shearing, which is required to get best possible homogenisation. In comparison to conventional single screw extruders, used in film recycling, a co-rotation twin screw provides significantly better homogenisation. Therefore, it is possible to set new quality recycling levels, which allow a significantly wider use of the recycled pellets.
The screws in conical design are segmented and adjusted with exchangeable mixing / kneading elements. The tailored screw geometry, in combination with the suitable screw speed, allows to adjust the shearing rate to the exact required level to prevent gels and cross linking.
Because of the short processing unit of the MAS extruder, the total connecting power and the general production costs related to output quality are very low. Based on data from existing MAS customers, the energy consumption with PE is approximately 0,32 – 0,35kw/kg for the extrusion process and melt filtration.
