EXHIBITION REVIEW | PLAST 2018

compounding extruder
used the event to mark the full commercial intro- duction of its latest generation TM-HF high torque twin-screw extruders, which were first seen in prototype form at K2016. There are nine models in the series, with motor powers ranging from 66 up to 4,180 kW and respective total torques ranging from 485 up to 39,919 Nm. At Plast, the company showed a middle-of-the-
range example, the TM-HF 58. Maris Sales Manager Luciano Gallino said the extruder is designed to provide a specific torque of up to 15 Nm/cm3
,
although the gearbox is capable of delivering up to 18 Nm/cm3
. Intended principally for compounding
of engineering thermoplastics, the TM-HF 58 can deliver an output of up to 1,500 kg/h, although an output of around 1,000 kg/h is more typical for production of glass reinforced polyamides. The unit will accept up to three side feeders. ICMA San Giorgio was emphasising its expertise in both compounding and recycling technology. The Italian compounding machinery specialist had two compounding extruders on its stand, one an HT unit for processing waste with low bulk density and the other an HP-t 40 “i-Smart” model. The latter offers an increased torque capability up to 18 Nm/ cm3
and a nominal D/d ratio of 1.55. ICMA’s i-Smart solution involves the extensive application of sensors to enable preventive diagnostics. CEO Giorgio Colombo said the company is
currently developing a compounding unit for direct extrusion of profiles with cores in post-consumer waste. He also highlighted its technology for production of multilayer membranes incorporating recyclate, illustrating this with a system based on three twin-screw extruders feeding a calender (also produced by the company). “ICMA was one of the first companies to propose direct extrusion,” Colombo said. ICMA San Giorgio is hoping to benefit from the incentives for recycling of highly contaminated

post-consumer waste (Plasmix) approved by the Italian government earlier this year. These provide for a tax credit of up to 50% for purchases of Plasmix products. Co-rotating twin-screw extruders and extrusion lines developed by ICMA San Giorgio within its Ecoimpatto development project “represent the most advanced frontier to transform these extreme materials into commercial artefacts, usable in different areas,” the company claims. Italian compounding equipment maker Comac demonstrated an EBC 90HT/52D co-rotating twin-screw extruder. The unit, which featured very long screws (L:D 52) was designed for Spanish company Torraspapel for production of adhesive resins for labels. Output is around 1,500 kg/h. Comac claims a leading position in the market for equipment for production of these types of materials. Project engineering is now one of the key focus
areas for Farrel Corp, part of Farrel Pomini (itself part of the HF Mixing Group), according to Sales Applica- tion Engineer Jonathan Leeming. The company can provide complete turnkey systems (excluding buildings and other basic infrastructure) for produc- tion systems based on its FCM and LCM continuous mixers. As an example of the company’s capabilities
