Haselsteiner GmbH has developed an automatic tempering furnace bed loading and unloading system with automatic glass lite nesting. With this system, a tempering furnace bed can not only be loaded quicker and more continuously, but also automatically unloaded again and the glass lites separated. A decisive factor of this system is that it doesn’t touch the coated glass surface on any glass lite during the loading, nesting, unloading or separation of each glass lite.
Since in most cases a glass tempering plant has a very high-power consumption and therefore causes high operating costs, an optimal use of the plant is of utmost importance. This said, in many cases a higher utilization is not easy to realize for organizational reasons, however a higher furnace bed loading (use of bed size) and a higher number of oven loadings per hour are the basic requirements to reduce the tempering costs per m² of glass.
The best way to reduce the tempering costs per m² is to increase:
- Glass density of the bed loading
- Number of oven loads per hour.
Main features of the Haselsteiner system:
- No manual glass handling – neither at the inlet side nor at the outlet side of the furnace.
- No limitation of glass size except nothing smaller than 16 x 16”
- For rectangular and square glass sheets (straight line shapes on request);
- No limitation in relation to the weight of the glass.
- No limitation for soft coatings or low-e glass;
- It never touches the coated glass surface.
- Glass panes can be rotated by +/- 90 degrees.
- Highly efficient mechanical nesting on the tempering bed.
- Individual glass sheet loading adjusted for best tempering quality.
- Faster and continuous bed loading.
- Higher furnace loading per hour, more cycles.
- The loading side and unloading side communicate with each other = “continuity”.
- Better tempered glass quality through continuous loading.
- Reduction of costs per m² of tempered glass due to higher plant utilization.
- Potential savings in personnel.
- pNo risk of injury to personnel.
- No loading errors.
- Reduced CO2 costs per m² of tempered glass.
