Coperion’s enhanced ZSK Mc18 twin screw extruders are loaded with new features that optimize convenience and handling, while minimizing downtimes and energy use.

These machines can be implemented for various applications in plastics recycling: for regrinding plastics such as HDPE, PP, ABS, PS, and PVC, for manufacturing films, for PET recycling, and for upcycling of various materials.

Included is the next generation of user-friendly extruder controls. These can be individually modified for customer requirements and, thanks to smart features, can be seamlessly integrated into Industry 4.0 environments. Furthermore, the modern user interface is convenient and intuitive to operate.

The new ZSK extruders come with one-piece insulation covers that can be detached without removing the cartridge heaters and that optimally insulate the process section, simplifying use and leading to higher energy efficiency. One further convenience function is the pluggable cartridge heaters that allow efficient temperature control on the inside of the barrel. They are individually connected using IP67 plugs and service staff can remove them for maintenance in no time. The gearbox lantern can be optionally equipped with an electronically secured maintenance opening. As soon as the screw shafts come to a complete stop, service personnel can open the gearbox lantern without tools, guaranteeing secure, easier access to the screw shaft coupling during maintenance, which again reduces the machine’s downtimes, thus contributing to greater efficiency.

Another new feature on the ZSK 45 Mc18 is that the process section is no longer assembled with tie rods. Instead, each barrel is equipped with flanges, making disassembly of individual barrels markedly faster than before.
