According to the record of the investor relations activity of Suzhou Shihua New Material Technology Co., Ltd. (688093.SH), the market space of photoelectric products is quite large. From the global market perspective, it can reach at least several billion Chinese yuan, and Japanese and American companies occupy the main market position. The single project volume of photoelectric products can reach around tens of billions of yuan. In the first half of 2023, the company's optical production line was smoothly put into operation, and new photoelectric products were certified and mass-produced for new customers, breaking the monopoly of foreign companies and achieving import substitution. At present, it is gradually increasing sales. In order to improve the production capacity and efficiency of optical materials, the company has added a new high-speed production line, which is expected to be put into use this year. Continuous stable production of photoelectric materials is very important. Due to the continuous precipitation and accumulation of the company in optical materials in the past few years, the company's capabilities have been recognized by customers. At present, the company is actively promoting the sampling and verification work of other optical products, and is expected to continue to achieve production and sales of some new products this year.
