What are the automotive glass production processes?

Raw material pre-processing. The bulk material (quartz sand, soda ash, limestone, feldspar, etc.) is pulverized to dry the wet raw material, and the iron-containing raw material is subjected to iron removal treatment to ensure the quality of the glass.

      Preparation of batch materials.

      Melt. The glass batch material is heated at a high temperature (1550~1600 degrees) in a kiln or a kiln to form a uniform, bubble-free liquid glass that meets the molding requirements.

       forming. The liquid glass is processed into articles of a desired shape, such as flat plates, various utensils, and the like.

       Heat treatment. By annealing, quenching, etc., the stress, phase separation or crystallization inside the glass is eliminated or generated, and the structural state of the glass is changed.
