To create glass that is difficult to break, there are two methods: "thermal tempering" and "chemical strengthening." "Thermal tempering" involves heating the glass to near its softening temperature (about 650-700°C) and then rapidly cooling it, which generates compressive stress on the surface. "Chemical strengthening," also known as chemical tempering or ion exchange strengthening, enhances the glass by inducing a chemical reaction on its surface. The thickness of the replacement layer varies depending on the type of material. *For more details, please refer to the PDF document or feel free to contact us.*

To break glass, it is often due to physical factors such as "making contact with a hard object on glass or mirrors" and chemical factors like "pouring hot water into a cup." When cooling and solidifying glass products, there are countless tiny scratches (cracks) on the surface that are not visible to the eye, and the scratches (cracks) at the points of contact with hard objects spread and cause breakage. Additionally, it is generally said that when the temperature difference exceeds 60°C, the risk of glass expanding and breaking becomes very high. Pouring 100°C hot water into a cup at 20°C (room temperature) significantly increases the risk of breakage. *For more details, please refer to the PDF document or feel free to contact us.*

Glass has the property of being strong against compressive stress (forces that try to compress it) but weak against tensile stress. This is the mechanism by which glass breaks due to the tensile stress that occurs on the opposite side.

This is an introduction to examples of the production of chemically strengthened special glass (special processing technology). Since the strengthening tank is heated to very high temperatures, there may be instances of substrate cracking during the insertion and removal of the substrate. To prevent such cracking, we have know-how in preheating, slow cooling, and jigs to hold the substrate, and it is not an exaggeration to say that the culmination of our in-house technology is present here. Currently, we are also finishing the strengthening of large digital signage and large bent glass, and customer satisfaction has been increasing significantly. 【Case Overview】 ■ Request: Chemical strengthening ■ Materials: Soda glass, of course, as well as aluminosilicate glass for strengthening, and other glass excluding non-alkali ■ Size: Strengthening possible from ultra-small sizes up to 1500mm x 780mm ■ Product details: From small mobile substrates to large substrates for digital signage *For more details, please refer to the PDF document or feel free to contact us.

This is an introduction to a case study of special processing technology for non-alkali glass (size reduction). When processing mask substrates that are patterned with high precision and accuracy, the challenge was to cut them without damaging the appearance and to finish the pattern position as required. To address this, we applied masking, performed cutting, and used a machining center equipped with a camera for positioning and shaping. Furthermore, we ensured that the external dimensions met the requirements, and by measuring the pattern position with an image measurement machine, we were able to satisfy our customers, leading to repeat orders. [Case Overview] ■ Request: To reduce the size of a patterned mask substrate to a smaller dimension ■ Product Specifications: Etched position requires an accuracy of ±0.05 Appearance (scratches, etc.) must have a defect rate of "0" under high-brightness lamps ■ Material: Non-alkali glass ■ Size: Reduced from 750×850 to 400×550 ■ Product Details: Request for size change of the existing product's glass (position and appearance are important) *For more details, please refer to the PDF document or feel free to contact us.
