Ballistic Glass Bending Furnace
Product Overview
Casso-Solar Technologies’ Ballistic Glass Bending Furnaces are specifically designed to bend ballistic glass with thicknesses up to 100mm. The heaters used in these furnaces are specified to operate at the ideal wavelength to penetrate through the entire glass thickness, allowing the multiple layers to heat and
bend evenly. This combined with precise closed-loop heat control minimizes the creation of process
slowing air gaps between the layers of glass. In addition, glass temperatures are monitored by optical
pyrometers to ensure repeatability from cycle-to-cycle.
Depending on the required throughput, Casso-Solar offers multiple different configurations for these
bending furnaces with the most commonly purchased options being single station and shuttle benders.
For a smaller up-front capital investment, a customer can purchase a single station bender and easily
upgrade it to a shuttle bender in the future. A single station bender includes a bending furnace and either 1 or 2 carts.
A shuttle bender adds preheat/anneal stations to either side of the bending furnace,
which increases the system efficiency by minimizing how much time a part needs to remain in the
bending chamber.

Features
- Flexible zone control allows for precision heat profiling to deliver heat exactly where needed within the part
- Up to (100) zones of control in both X and Y directions to allow for primary and cross-curvature bend profiles. For further flexibility zones can be assigned to control groups for nearly unlimited flexibility.
- Built using Casso-Solar outerwound tube heaters, which are more efficient than typical ceramic tube heaters used in other furnaces
- Automated PLC control with touchscreen HMI provides recipe storage for easy recall
- Furnace can be programmed to run cycles based off heater power output, furnace temperature or glass temperature
- At final bending stage, process can be manually shortened or lengthened as needed. Heater output can also be easily modified on-the-fly.
Specifications
- Can be built to accommodate customer's preferred maximum glass size. Casso-Solar has built these furnaces up to 4m x 2.4m in the past.
- Capable of accurately bending glass stacks up to 100mm thick
- Works with both ring and full surface molds
- Voltage as specified by customer (208V, 240V, 380V, 400V, 480V, 575V, etc.)
- 8" (200mm) Insulation Thickess
- Can bend multiple windscreens or sidelites in same cart
Industries/Applications
- Automotive Windscreens and Sidelites
- Architectural Glass
- Primarily designed for Ballistic Glass Bending Applications, but can also be used for standard glass bending
Available Options/Customizations
- Heaters can be added to the cart walls or floor to provide additional heat directly into the mold
- Height-adjustable crease heaters can be added for localized heat to help form tight bend radii
- Multiple pyrometers can be installed to allow customer to monitor multiple windshields or sidelights in a single batch
- Insulated covers for carts can be supplied for a single station bending system to allow for annealing and cooling to take place after the glass has been removed from the bending furnace
- Moveable carts floors that allow the overall volume of the cart to be minimized for parts with shallow bends
- The addition of forced and/or radiant cooling systems can further speed up the annealing and cooling process to reduce cycle times
- Standard carts are moved into place manually, but a powered drive system can be installed for operator ease
- Access doors can be added to carts
- Preheat/Anneal stations
