There may be a certain difference between the displayed temperature of each press oven and the actual temperature inside the oven due to model and maintenance in differences. When you use AZDENT press ingots, please check if the press molding procedure is suitable for your press oven; If the edge of the restoration is incomplete or if the ring is cracked during the press flow process, please increase the maximum temperature by 3 ℃ and start again; If there are traces of tiny air bubbles on the catering surface, please lower the maximum temperature of 3 ℃ and start again; Discover the optimal press flow temperature suitable for your press oven by the above means.
