A mold with a multi-layer coating is disclosed. The mold may include a mold body having an outer surface and a multi-layer coating disposed on the outer surface. The multi-layer coating may include a diffusion barrier layer disposed on the outer surface of the mold body and an intermetallic layer disposed on the diffusion barrier layer, wherein the intermetallic layer comprises Ti, Al, and an additional metal selected from the group consisting of Zr, Ta, Nb, Y, Mo, Hf, and combinations thereof The diffusion barrier layer may restrict diffusion of metal from the mold body to the intermetallic layer.

Various embodiments provide a mold including a pyrolytic carbon film disposed at a surface of the mold. Various embodiments relate to using a low pressure chemical vapor deposition process (LPCVD) or using a physical vapor deposition (PVD) process in order to form a pyrolytic carbon film at a surface of a mold.

In a method of making shaped glass articles, a glass sheet is placed on a mold having a shaping surface with a desired surface profile of a shaped glass article. The glass sheet is preferentially and rapidly heated by radiation while in the vicinity of the mold so that the mold remains substantially cooler than the glass sheet during the heating. The glass sheet is sagged onto the shaping surface of the mold so that at least a portion of the sagged sheet assumes the desired surface profile of the shaped glass article. After sagging and shaping, the sagged and shaped glass sheet is removed from the mold.

The invention provides a method of making a vessel having a sculptural interior, comprising attaching a textile core to the air inlet port of an I.S. machine, inserting a gob of molten glass into a mold to surround the textile core, applying compressed air to press the molten glass around the textile core, applying compressed air to inflate the textile core creating the bottle, allowing the bottle to cool sufficiently to withdraw the core from the bottle, and withdrawing the textile core from the bottle.

A method of reforming glass includes placing a glass sheet on a mold having a shaping surface for forming the glass sheet into a shaped glass article. A target starting mold forming temperature and temperature window are selected for the mold. A target starting mold forming temperature and temperature window are also selected for the glass sheet. The glass sheet and mold are simultaneously exposed to a first furnace condition controlled to a furnace temperature set point above the target starting mold forming temperature until a temperature of the mold is within the first temperature window. The glass sheet and mold are simultaneously exposed to a second furnace condition controlled to a furnace temperature set point between the target starting mold forming temperature and first furnace temperature set point until a temperature of the glass sheet is within the second temperature window, after which forming of the glass sheet starts.

A glass molding apparatus includes at least one molding part including a molding cast configured to mold a glass, a transfer roller part including a plurality of transfer rollers below the molding part, the transfer rollers being arranged along a first direction, being configured to rotate in a first rotation direction to transfer the molding part along the first direction, and being configured to apply heat to the molding part, and a plurality of pressure parts configured to apply pressure to the molding part.

A bending station for a bending device, includes two bending molds, a pressing frame arranged to adapt to the glass sheet and to press it against an upper mold, the upper mold including a molding face, the area of which, defined by projecting the contour of the upper mold onto a horizontal plane, is greater than the area defined by projecting the outer contour of the pressing frame and the glass sheet onto the same horizontal plane, the pressing frame including a pressing ring having a continuous surface, the upper mold including a flexible sheet associated with an upper series of translational elements, wherein the upper mold is able to deform under the effect of the translational elements of the upper series in order to obtain a deflection value varying by at least 5 mm.
