In optical glass production, we are pushing forward with development of production technologies unbound by convention in a perpetual effort to improve quality and cost cuts. In addition, we actively strive to develop and produce glass for special applications based on the technologies we cultivated with optical glass.
This process measures the raw materials for glass in grams and blends them. After measurement, the raw materials are uniformly stirred in a mixer, and then packed into bags and boxes to be carried to the next process.
The mixture of raw materials prepared in the previous process is melted in a melting furnace at a high temperature, ranging from 1,000 to 1450 °C. This melt is then poured onto a tray-shaped platform to solidify before being crushed manually and by machines into small glass pieces called cullets, which are brought to the next process.
An amount of cullets is weighed out to the specifications in the retrieval instructions, and then they are checked with a metal detector before going to the next process.
The cullets measured out in the previous process are put into a melting furnace and melted at a high temperature. In this process, air bubbles and foreign substances are removed. After that, the melt is poured into a metal mold in which a glass plate is formed.
This process examines products and test pieces. Test pieces that are approximately 15 cm long are taken at intervals of 5 meters. Testing machines check the quality of various aspects of the test pieces, such as the inclusion of any air bubbles, paying the utmost attention to prevent any nonconforming products from going out. Conforming products are cut and measured and then transported to the warehouse.
This process measures the raw materials for glass in grams and blends them. After measurement, the raw materials are uniformly stirred in a mixer, and then packed into bags and boxes to be carried to the next process.
Materials mixed in the previous process are melted in a high temperature, higher than 1500 ℃, melting furnace until they become a liquid. Then, the molten glass flows through a pipe and is poured into a round metal mold. Then, it is cooled to a predetermined temperature and it solidifies.
