The Advantage of BS6088A Spherical Glass Beads
1. With rich production experience, the quality of glass beads is controlled by adjusting furnace temperature, induced draft fan, and cooling water, so our products have very high roundness, and the appearance of glass beads is clear and free of bubbles.
2. We cooperate with glass factories to choose the best raw materials and give quality commitment from resources.
3. We have a 24-hour quality control system to ensure that each batch of glass beads is of the same quality
4. Factory advantage, we can give the most competitive price
