Description

Technical Field

The purpose of annealing is mainly to eliminate internal stress, ensure the stability and durability of the finished product, and at the same time improve the strength of the glass crafts, improve transparency, ensure dimensional stability and extend the service life. After the annealing process is completed, the high-temperature glass crafts need to be cooled. Cooling is also an important step in the production process of glass crafts.
