Excellent mirror finish! We will provide according to your needs.
Binderless molds (glass lens molding) can achieve high mirror surface accuracy by controlling the WC particle size through a special sintering method. It is possible to achieve a Ra of less than 1nm. By combining thermal expansion coefficients, we can prevent core misalignment during lens molding. We can provide solutions tailored to your needs, from round bars to blank processed products. 【Features】 ○ Excellent mirror surface quality ○ Core misalignment prevention ○ Customized solutions to meet your needs For more details, please contact us or download the catalog.
