At Bright Sign Industry Co., Ltd., we manufacture and sell various glass beads tailored for special applications, in addition to general-purpose soda-lime glass beads. We offer "Low-Alkali E Beads" with an alkali content of less than 1.0%, as well as "Pressed Beads" that have minimal diameter variation within a lot due to the pressing molding process, and "Precision Polished Spheres" that can be manufactured with a sphericity precision of up to 5μm through surface polishing. We also handle "Precision Particle Size Micro E Beads." 【Features】 We are a comprehensive manufacturer of industrial glass beads established as the first in Japan using the rotary kiln method. With over 50 years of accumulated technology, we respond to a wide range of requests with products ranging from a few microns to 30mm in diameter. * For a size chart tailored to your application, please refer to the PDF document. * If you would like a sample, please select "Request Sample" in your inquiry.
