Abstract

Procédé de fabrication par coulée de pièces moulées en silicium, à symétrie de révolution. On fait tourner le moule 8 pendant l'opération de coulée, à 50-500 tr/mn autour de son axe vertical et on maintient par refroidissement sa température entre 800 et 1200 degrés C. Ces pièces de révolution sont utilisables en optique, dans le domaine infrarouge.Manufacturing process by casting molded parts in silicon, with symmetry of revolution. The mold 8 is rotated during the casting operation, at 50-500 rpm about its vertical axis and its temperature is maintained by cooling between 800 and 1200 degrees C. These parts of revolution can be used in optics, in the infrared domain.
