Mingdun Glass is one of the earliest high-tech enterprises in China to engage in the research and development and production of safety glass for rail transit.

Ordinary tempered glass (physically tempered), also known in the industry as safety glass, is the most widely used type of tempered glass today, offering fast processing and low cost. However, it has inherent defects such as spontaneous breakage, light refraction, and a low safety factor, affecting the user experience.

The industry generally considers the spontaneous breakage rate of physically tempered glass to be 0.3%. Even after homogenization furnace treatment, the spontaneous breakage rate can be reduced to 0.1%, but it cannot completely prevent the occurrence of spontaneous breakage. Spontaneous breakage of physically tempered glass is characterized by randomness, uncertainty, and suddenness.

Mingdun Company, adhering to the safety product concept of "impact resistance and penetration prevention," has addressed the shortcomings of ordinary tempered glass by employing ion replacement technology to produce ion-tempered glass (chemically tempered), which boasts higher safety performance and stronger impact resistance.

Mingdun Company has two ion tempering furnaces, which are independently designed and manufactured by Mingdun and have complete independent intellectual...
