Chamber furnace

custom-madefor the electronics industrysalt bath

Overview
Equipment for chemical strengthening of glass to reduce breakage. Designed for thin glass, the system provides high-precision temperature control even for large workpieces and can be custom-sized according to project requirements.

• Proven designs from small to large-scale installations.
• Maximum processed glass size to date: 1700 mm × 1600 mm.
• Expandable design to accommodate larger formats on request.
• Integrated warm/cold water bath washing systems can be supplied.

Details
Chemical strengthening is performed by ion exchange: glass is immersed in a molten potassium nitrate (KNO3) bath, allowing sodium ions in the glass surface to be exchanged with potassium ions. This process forms a compressive stress layer on the surface, increasing strength to more than five times that of untreated glass and improving resistance to breakage and surface damage.

Applications

• Smartphone cover glass
• Tablet glass
• ATM/front-panel cover glass
• Shaped and specialty glass
• Solar panel glass
