Title: LOW COST GLASS BENDING MOLD
Abstract:
A large percentage of the bent glass laminates manufactured worldwide each year is produced using the gravity bending process. Inherent drawbacks to the process include the expense of the molds required, marking of the glass by the mold and the lack of precise surface control. By using an inexpensive ceramic mold to bend a sheet of glass having a higher bending temperature than the glass to be used in the fabricated product, a glass female is produced which is then provides the means to produce a full surface gravity bending mold which produces parts having superior quality, optics and dimensional control.
