A method for manufacturing curved glass sheet includes the following: an equipment, including a matching first mold core and a second mold core, is provided; a raw glass sheet is provided and placed on the second mold core covering second mold cavity; a pressure is controlled in the first and second mold cavities to a first pressure; the mold cores are closed and heated, to raise the raw glass sheet to a temperature of about glass transition temperature of raw glass sheet; a gas is supplied into the first mold cavity to raise the pressure in the first mold cavity to a second pressure which is greater than first pressure, in which the raw glass sheet is bent to the second forming surface of second mold core under pressure; mold cores are opened and cooled down to obtain the curved glass sheet.

Method and equipment for manufacturing curved glass sheet

A method for manufacturing curved glass sheet includes the following steps: providing a mold which includes a first mold core and a second mold core corresponding to the first mold core; providing a raw glass sheet and placing the raw glass sheet on the second mold core; heating the first mold core to a first temperature, and heating the second mold core and the raw glass sheet to a second temperature which is equal to or lower than the glass transition temperature of the glass sheet but higher than the first temperature; closing the mold and hot pressing the first mold core on the glass sheet; opening the mold, and cooling the glass sheet to obtain the curved glass sheet. An annealing step can also be provided to the curved glass sheet. A mold for manufacturing the curved glass sheet is also provided.
