Electric Atmosphere Controlled Bell Type Annealing Furnace For Optical Glass Annealing Heat Treatment
1﹑Application
Annealing is a heat treatment process for glass and soft metals that reduces hardness, increases ductility and helps eliminate internal stresses. Annealing oven—also called an annealing furnace—heats materials to a specified temperature and then cools it at a very slow rate.
Annealing glass furnace applies high heat to alter the microstructure of a material and change its mechanical or electrical properties.
It is suitable for precision annealing of molded glass lenses of different calibers such as mobile phones, security cameras, and self-driving car cameras.
