The present disclosure is directed to methods and techniques for gob-pressing a glass part of challenging geometries, such as large surfaces with thin thickness as well as features positioned far from a centroid of the part.

Glass parts and gob-pressing methods for making such

The present disclosure provides an apparatus and method for modifying the shape of a hollow structure. The method may comprise steps of providing a hollow structure having a cross-section with first and second diameters defining a first aspect ratio; heating at least a part of the hollow structure to at least its glass transition temperature, forming a malleable hollow structure; maintaining a positive pressure inside the malleable hollow structure to form a pressurized hollow structure; and pressing against a first side and an opposed second side of a heated part of the pressurized hollow structure, forming a hollow tabular structure having first and second opposed generally flat faces and a second aspect ratio greater than the first aspect ratio.

Manufacturing process to reform glass tubes

A method for bending a sheet of material into a shaped article includes providing the sheet of material. A reformable area and a non-reformable area of the sheet of material are heated to a first temperature range corresponding to a first viscosity range. The reformable area of the sheet of material is subsequently heated to a second temperature range corresponding to a second viscosity range. The reformable area of the sheet of material is reformed into a selected shape by at least one of sagging the reformable area of the sheet of material and applying a force to the sheet of material outside of or near a boundary of the reformable area.

Method and apparatus for bending a sheet of material into a shaped article

A reformable area and a non-reformable area of a sheet of glass material are heated to a first temperature corresponding to a first viscosity. The reformable area is subsequently locally heated to a second temperature corresponding to a second viscosity, where the second viscosity is lower than the first viscosity. A bend is formed in the reformable area during the local heating of the reformable area by contacting a first pusher with the non-reformable area and translating the first pusher along a linear path to apply a pushing force to the non-reformable area that results in the bend in the reformable area or by contacting a second pusher with an edge area of the reformable area and rotating the pusher along a circular path to apply a pushing force to the edge area of the reformable area that results in the bend in the reformable area.
