Automatic Tempering Process and Low-E

Toivo Janhunen & Tarmo Pesonen, Tamglass Engineering Ltd. Oy

The growing use of Low-E glass has underlined a number of important aspects in the tempering process. This presentation addresses the drivers of and benefits from the application of advanced process control particularly in the case of Low-E glass.

Low-E glass is much more sensitive to the heating parameters in comparison with normal “high-emissivity” glass. The heat must be focused at the right time to the correct position and side of the glass to avoid losing the flatness of the glass. A fast furnace with automatic control and on-line quality monitoring has proven itself as the right technology for proper processing. Experiences from the use of this new technology have demonstrated that the optical quality of the glass has improved and stayed on a high level and at the same time the productivity and yield of the process have improved.
