The surface of the tray is provided with a hexagonal slot that slides into the support column. The height of the support column is adjustable. The tray can be assembled into a multi-layer structure to increase the area occupied.
The production volume and efficiency of all-ceramic dentures have been increased. Through the multi-layer structure design, the area occupied by the refractory tray in the firing furnace has been increased, thereby improving the production efficiency of all-ceramic dentures.
