Lumina

Lumina Series

Chemical Tempering Furnace

Lumina M is a high volume multiple chambers chemical tempering furnace used for mass production of thin glass products requiring zero optical distortion via the process of iron exchange. By immersing the glass into a Potassium Nitrate chemical bath, 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.
