The first bending and tempering system to Sunglass was supplied in 1999. This was the first throughput version, which means that one end of the furnace is used for loading and the opposite end for unloading, thus increasing the capacity by approx. 60%. The maximum glass size is 2,200 x 3,500 mm. The final design was implemented in co-operation with the client.

Soon there was a need for another Rainbowmaker. Architects wanted wider arcs and it was time to develop another system. The size required was quite the opposite of the one used before, girth 3,500 mm and height 2,600 mm. Using gravity bending method this called for automatic central support. The new Rainbowmaker TSFe 350/260 was delivered in the year 2000.

Sunglass Managing Director Giuseppe Bergamin says; "We had been involved in the bending and tempering business for quite a long time, but not for the large architectural applications. We saw a clear need for the product. The market has been very good and improving constantly, so it was a right decision to make. Glassrobots has always been an innovative first class partner."
