ATOMCESS
REPAIR OF COMPONENTS BY ADDITIVE MANUFACTURING FROM POWDER STEEL
WINOA's current product is carbon steel shot between 100 µm and 2 mm. The production of special steel shot enables the use of applications with significant economic and environmental added value, working with granulometries similar to the nano scale. For this, it is necessary to use other technologies, such as atomisation by centrifugation (new in the Basque Country), in which WINOA also has a practical advantage due to its size and accessibility of installations.
Repair of defective parts from large castings by additive manufacturing could be beneficial for some 450 tonnes of special steels in high-value parts that are remelted annually in their manufacturing facilities due to minor non-repairable defects, with a consequent energy impact (consumption of 700 kWh per tonne). Although additive manufacturing may have great potential for the repair of these parts, it is still far from being applicable to mass production. However, in the case of ATOMCESS, the application is interesting as it involves the repair of extremely high-value units.
WINOA, world leader in the production of steel abrasives, is the promoter of ATOMCESS, with the participation of the CEIT Technology Centre, the circular economy consultancy firm, ZICLA, and the collaboration of the AMPO and TUBACEX steel companies.
