SYSTEMS AND METHODS FOR THERMALLY CONTROLLING WARP

摘要

Embodiments disclosed herein include systems and methods for controlling material warp that include placing the shaped mold in a heating device, forming a glass material into a shaped mold, and cooling the glass material and the shaped mold to a predetermined viscosity of the glass material. Some embodiments include, a predetermined time prior to removing the glass material and the shaped mold from the heating device, holding the glass at the mold in the heating device where the heating device temperature is substantially equal to mold and glass temperature just prior to exiting to ambient temperature. Some embodiments include removing the glass material and the shaped mold from the heating device to further cool the glass material and the shaped mold at ambient temperature, where after removing the glass material and the shaped mold from the heating device, the glass material will exhibit controlled or desired material warp.

1. A method for controlling material warp, comprising:
placing a glass material and shaped mold in a heating device to heat the glass material and the shaped mold; forming the glass material into a shape of the shaped mold; cooling the glass material and the shaped mold to a predetermined viscosity of the glass material; holding, for a predetermined time prior to removing the glass material and the shaped mold from the heating device, the glass material and the shaped mold in the heating device where a temperature of the heating device is substantially equal to a temperature of the shaped mold and the glass material just prior to exiting the heating device into ambient temperature; and removing the glass material and the shaped mold from the heating device to further cool the glass material and the shaped mold at the ambient temperature, wherein after removing the glass material and the shaped mold from the heating device, the glass material will exhibit a desired material warp.
