Abstract
(EN)
Provided are an ejection apparatus having improved controllability in fixing positions of particles, a molding apparatus, a method for operating an ejection apparatus, and a method for manufacturing a molded body. The present invention relates to an ejection apparatus used to fix particles by colliding the particles onto a fixation surface, the ejection apparatus comprising: a first ejector for ejecting aerosol containing the particles toward the fixation surface at a first ejection speed; and a second ejector for ejecting a gas toward the fixation surface at a second ejection speed faster than the first ejection speed, wherein the second ejector ejects the gas by allowing the gas to at least partially overlapping with the aerosol, thereby accelerating at least a part of the aerosol toward the fixation surface to fix the particles on the fixation surface.

L'invention concerne un appareil d'éjection présentant une meilleure aptitude à la commande dans des positions de fixation de particules, un appareil de moulage, un procédé de fonctionnement d'un appareil d'éjection, et un procédé de fabrication d'un corps moulé. La présente invention concerne un appareil d'éjection utilisé pour fixer des particules par collision des particules sur une surface de fixation, l'appareil d'éjection comprenant : un premier éjecteur destiné à éjecter un aérosol contenant les particules vers la surface de fixation à une première vitesse d'éjection ; et un second éjecteur servant à éjecter un gaz vers la surface de fixation à une seconde vitesse d'éjection plus rapide que la première vitesse d'éjection, le second éjecteur éjectant le gaz en lui permettant de chevaucher au moins partiellement l'aérosol, accélérant ainsi au moins une partie de l'aérosol vers la surface de fixation pour fixer les particules sur la surface de fixation.
