Dielectric film from cast line
Davis-Standard has supplied a cast film line to US-based Peak Nano Films – a specialist in dielectric film for capaci- tor applications.
With the equipment,
Peak Nano Films will move into production with a new film for the automotive, military, electrical grid and industrial markets. The company says the na- nolayered film is the first major materials improve- ment for solid-state film capacitors “in decades”. Davis-Standard helped
validate the process and tailor machinery based on the company’s needs. “Davis-Standard’s technical expertise enabled us to collaborate on new processes, and define machinery features prior to purchase,” said Mike Hus, senior vice president of engineering at Peak Nano. Peak Nano says that its dielectric film structure overcomes current technology challenges to provide longer capacitor life, higher temperature resistance, greater breakdown strength, and a smaller footprint for capacitor designs. The new line includes a custom feedscrew, which was designed specifically to adapt to the process requirements for this dielectric film. �

46 RECYCLING Removing recyclate smells
Kreyenborg has devel- oped a new technology to help reduce the odour of recycled plastic waste. Its IR-Fresh is a modular system that removes strong-smelling substanc- es from recyclate. In the first process step,
an infrared module – in- stalled above the material bed – heats the material to its optimum temperature. Continuous rotation of a drum ensures homogene- ous mass flow with a defined dwell time. Due to the rotation and mixing elements being integrated in the spirals, the material is continuously mixed in the drum with constant surface exchange. Com-
BLOWN FILM Making heavy-duty bags fast
Reifenhäuser says that a high-performance cooling system has allowed it to make heavy-duty bag at rates of more than 600 kg/h. The Ultra Cool 2.0 FFS
system, for its Evo FFS blown film line, manages to boost throughput while maintaining optimum film properties thanks to
high-precision, flow-opti- mized components, says Reifenhäuser. By running at 600 kg/h,
Reifenhäuser says it exceeds typicaly high outputs by 50-100kg. Evo Ultra Cool 2.0 FFS is suitable for all common formulations and applications (such as consumer goods and agricultural film).
“With an output exceed- ing 600 kg/h, we provide our customers with an attractive return on invest- ment – and the potential prospect of long-term success on the market,” according to Eugen Friedel, sales director at Reifenhäuser Blown Film. For its Evo FFS lines,
Reifenhäuser offers the premium version (Ultra Cool 2.0 FFS) and standard version (Evo Cool FFS). All Evo FFS lines are equipped with Reifenhäuser Eo extruders and die heads for optimised melt quality at low melt temperatures, says the company. �

bined with controlled heating, this ensures considerable odour elimina- tion, even in a short time. In the second process
step, any remaining odorous substances in the regrind or granules are removed by a thermal-physical cleaning process in the IR-Fresh Conditioner – an insulated
hopper that keeps the material at a temperature that is matched to the decontamination process, by means of a hot purge-gas. The IR-Fresh process can be used continuously in two stages both, for regrind (before extrusion) and for granules (after extrusion). �
