METHODS AND APPARATUS FOR PRESSING GLASS OR GLASS-CERAMIC PREFORMS TO FORM SHAPED PLATES, METHODS FOR MANUFACTURING LIQUID LENSES, AND LIQUID LENSES

Abstract:

A method includes pressing a preform with a mold including a mold body and a plurality of mold protrusions extending from the mold body at a pressing temperature and a pressing pressure sufficient to transform the preform into a shaped article including a plurality of cavities corresponding to the plurality of mold protrusions. The preform is formed from a glass material, a glass-ceramic material, or a combination thereof. The mold body is formed from a porous material. The plurality of mold protrusions is formed from a non-porous material.
