Replacing metal in heavy-duty parts

The InterWet technology features numerous interesting references in several fields of the industry, from transportation to industrial air conditioning The products developed by the Italy-based Polieco stand for their originality and final use: round, square and rectangular manholes are manufactured at a very serious daily rate using a complete production island supplied by Cannon Afros. Characterised by an attractive look and a perfect surface finish, the manholes manufactured under the Kio trade name are moulded is several shapes, dimensions and functions. Conventional flat covers or holed grills can be produced in sizes from 400 x 400 mm up to 700 x 700 mm or 800 mm diameter for the round ones.[image_1_right] Their main advantage towards conventional products made in steel or cast iron is their lightness, which makes the operations of installation and maintenance easier and safer: the weight of the Kio covers is 70 % lower than the weight of European made cast iron ones. This allows the handling by one only man, fully respecting the safety laws that limit to 25 kg the maximum weigh of handled goods. Several other advantages characterise these polymeric manholes: Solidity and resistance: a standard model can stand the weight of up to 40 tonnesElectric insulation: it protects pedestrians from accidental electrical shock in humid or wet environments and presents little interference with the radio frequency, satellite or cell phone signals of modern transmission systems.Noise reduction: these covers do not «clang and rattle» under road traffic, avoiding any acoustic disturbance to the inhabitants.Resistance to corrosion and to chemical agents: they are not subject to rust, corrosion, condensate. They are particularly suitable for seaside resorts, food and chemical industry and petrol stations, also because they are completely spark-free.Environment protection: the CO2 impact of a polymeric product is several times lower than that generated by a traditional metal casting operation, resulting in a "greener" product.Customization: the frames or the covers can be produced in different colours for different utilities/applications, personalising the upper part of the cover with the name of the customer, service or sponsor.The synthetic products are not appealing for thieves that steal and resell the metallic manholes to the scrap yards. [image_2]The Cannon equipment - one high-pressure metering unit  and FPL InterWet head, the glass-dispensing system connected with the robot manipulating the head, two presses and all the relevant controls and safeties - started in December 2011 and is now producing on three shifts for five days per week. The capacity of every press is from 150 pieces per day for the smallest square model to 100 pieces per day for the largest round one. Polieco is now planning to produce covers with a coloured surface, and to increase the range of products to new models and sizes.
