In partnership with the company NORCAM-Engenharia e Design Industrial, Lda, ALTO has developed a support for an artefact of the castle of S. Jorge. The EGEAC, Lisbon City municipal company responsible for the management of equipment and cultural animation, recovered parts of a historical artefact for the castle of S. Jorge and with the purpose of the exhibit it at the Museum of the Castle, requested us to manufacture a support for this artefact. The development of support was made by NORCAM and ALTO. This support has been designed and engineered according to the parts recovered (about 1/4 of the entire artefact) and so that all the pieces were properly accommodated and highlighted. The support, which has the shape of the original artefact but with the clipping of the part found, was manufactured in polyurethane, machined by the robot that the ALTO has and the finish was done with matte painting to give emphasis to the piece that it will bear. This artefact and respective support, so the restore operation is completed, will be exhibited at the Museum of the castle of S. Jorge, contributing ALTO in this way, to help preserve the historic Portuguese heritage.
