Right: Tecnomatic takes scraps from artificial grass produc- tion and uses an Atlas 75.30 extruder to make new reel support cores
Another advantage of the NG’s processing unit
is reduced energy consumption, which is around 15% lower than the previous SolEx series. Conse- quently, the series offers advantages both process and energy efficiency advantages, says Battenfeld- Cincinnati.
produce high-quality reel support cores. To do this, Tecnomatic adds an anti-humidity volumetric dosing system into the line. This accurately meas- ures and regulates the input of recyclate, prevent- ing fluctuations in material properties due to moisture content. The Venus 160 die-head is also critical, being
responsible for shaping the extruded material into the desired core dimensions. The technology precisely controls the core’s diameter and thick- ness, ensuring consistency across the process. In addition, the die-head’s versatility allows for the production of various core sizes up to 130mm.
Small addition Battenfeld-Cincinnati has completed its SolEx NG series of high-speed extruders by launching a new model.
Right: Battenfeld- Cincinnati says its SolEx NG series have higher output and reduced energy
consumption At NPE 2024 , it added the SolEx NG 45 to the
four existing models in the series – SolEx NG 60, 75, 90 and 120. The range boasts high output rates at low screw speeds, effective melting performance with low melt temperatures and a reduced pres- sure profile – leading to less wear on machines. The latest – and smallest – model, like its larger
predecessors, has a processing unit consisting of an internally grooved barrel combined with a matching screw geometry. The process technology advantages of this combination ensure a high quality for the extruded, semi-finished product, said the company. When processing HDPE, the extruders also achieve a 25% higher output – and 40% for PP, it added. In addition, it can achieve melt temperatures around 50F lower than that of conventional extruders.
34 PIPE & PROFILE EXTRUSION | Autumn 2024

Medical matters At the MD&M West show earlier this year, Davis- Standard – with partners Conair and Zumbach Electronics – demonstrated the extrusion of tapered medical tubing made from a photolumi- nescent blend of thermoplastic elastomer. Virgin Medalist TPE from Teknor and photolumi- nescent masterbatch are delivered via a blender, which creates the material mix. A TLM tube loader, mounted on the extruder hopper, draws the blended material from the hopper to the feed throat of a Davis-Standard 1in HPE (High Perfor- mance) medical extruder. The speed of the extrudate is regulated by a 10in HMI touchscreen control on a Conair Medline 1-12 Puller/Cutter unit. Rapid changes in tube taper and sizing are managed by ‘bump tube’ software in the Medline puller control; internal air-pressure changes are delivered by a Zumbach SPV-1 digital airbox.
Faster setup Bausano says it can speed up the setup of PVC pipe extrusion lines thanks to an innovative pipe head design. The new pipe head can cover a diameter range
of 125-400mm, with low flow rates (around 500 kg/h) – preventing material degradation and excessive dwell times in a balance of volume, flow rate, and production range. “The great challenge in terms of production
