EXHIBITION REVIEW | PLAST 2018

geometry of the shape to be punched. The machine is apparently intended to meet the needs of Austral- ian building companies, using profiles at least 2m long and with oval holes (around 16 by 7.5cm.) When filled with reinforced concrete, the profiles are used for building foundations. The system can be installed in-line after the cutting device, and offline. Format changes are quick and easy to make, and the pieces punched out can be recycled. Mixing equipment specialist Promixon chose to show machine elements at the heart of its plants: large blades for a horizontal cooling mixer and a 2000-L vertical tank with blades for four-stage powder mixing. The tank on display was fitted with two outlets, enabling it to feed two cooling mixers placed on opposite sides. The company, which is still young (it was founded in 2013) but has numerous staff members with long histories in the mixing business, continues to grow. It has new offices in Magnago, not far from Milan, and it is also expanding its team. Unicor said it is introducing more standardisa-

Balzanelli’s TR2500 PE double winder is a fully automated unit that coils the pipe, then transfers and ejects it
tion across its pipe corrugating equipment to improve costs. Different units will have the same switch cabinet, for example. The company showed a unit capable of producing tube for electrical conduit in diameters between 25 and 32mm at a rate of up to 60 m/min. This is a considerable increase on previous generations, due largely to a much more powerful cooling system. The main beneficiary is the UC36G2, designed for produc- tion of pipes up to 36mm in diameter, and which can hold up to 110 pairs of blocks.
Cool operators Plas Mec, which celebrated its 50th
anniversary last
year, showed two flagship machines, the Combi- mix-HC mixing system and the TRR container mixer. The first, used mainly for PVC dryblends, comprises
a TRM heating mixer and an HEC cooling mixer. The TRR container mixer is a multipurpose unit for applications where production changes are frequent and easy cleaning is very important – mas- terbatch is a typical example. Commercial director Massimo Grigolon says Plas Mec has increased its focus in recent years on efficiency, productivity and safe operation. He cites an improved water circuit design with enhanced cooling capacity on the HEC cooling mixer, as well as its new jacket that can withstand a working pressure up to 2.5 bar, typically found in factory closed circuit chillers. “With the Combimix-HC, it is now a straightfor-
ward task to cool more than eight batches per hour of U-PVC dryblend from 120°C to 40°C,” he said. Frigel Firenze, fresh from its acquisition of
fellow refrigeration system supplier Green Box, was on two stands to show the new breadth of its offering. Green Box specialises in the production of systems and equipment for water and fluid temperature control, and has important business with processing equipment OEMs. “We are delighted that Green Box is now part of
our group,” said Duccio Dorin, CEO of Frigel. “Green Box harbours considerable technical and innovative potential that – thanks to Frigel’s strong international position – will now be able to find its natural outlet.”
Chiller spotlight Piovan pointed the spotlight at its new Aquatech Easycool+ range of chillers that comply with European Union Ecodesign regulations – which come into force in 2021 – governing energy efficiency of such products.
It was also designed specifically for industrial processing of plastics. Most chillers, it says, are not
