Lumina Series

Chemical Tempering Furnace

The Lumina Sires are designed for high or low volume production for chemical tempered thin glass requiring zero optical distortion with single or multi chamber ovens.  Chemical tempering ovens use the process of iron exchange by immersing the glass into chemical solution where the sodium irons close to the glass surface are replaced by larger potassium ion atoms. As a result of this chemical exchange the glass has a stronger surface layer. Products using chemically tempered glasses include mobile phones, digital cameras, copy machines & aircraft windscreens.

Key features:

• Energy efficient insulation, heaters, quenching systems, drives and controls.  
• Pre heating glass tanks.
• Automatic process loading and unloading.
• Reaction time of between 3 – 8 hours (dependent upon stress level required).
• 9 point temperature measurement ±5°C (41°F)
• Heating time: 90 minutes.
• Cooling time 90 minutes.
• Conforming To EN12337-1:200, ASTM-C1422-99 & JC/T977-2005 standards.
