GELINDE primarily offers two major series of products: industrial high-precision components and optical elements.

Our industrial high-precision products encompass a variety of non-metallic spherical componets, including high-precision glass spheres, high-precision gemstone spheres, and high-precision ceramic spheres. We source materials from top-tier suppliers, covering a range of materials such as soda-lime glass, borosilicate glass, technical glass, quartz glass, synthetic rubies, synthetic sapphires, alumina ceramics, zirconia ceramics, silicon nitride ceramics, and more. With proprietary equipment and processes, we have built a solid reputation for high consistency and low variance in mass production. Our expertise lies in machining high-precision spherical components conforming to ISO standards, achieving precision levels up to G3 depending on the material.
