Abstract: Provided is a method of manufacturing a glass product including the following steps. An intermediate glass product is provided. A portion of the intermediate glass product is heated to a predetermined temperature. A tool and the heated portion of the intermediate glass product are brought into contact. Under a state that a tool contacts the heated portion, at least one of the tool and the intermediate glass product is rotated so that the tool and the intermediate glass product relatively rotate, wherein a part of the tool that contacts the heated portion comprises or is made of glassy carbon.

Abstract: A method for molding end portions on glass containers that store pharmaceutical active ingredients is provided. The glass containers are produced from a glass tube by hot-forming, an end portion having a neck opening using a centrally disposed opening forming tool interacting with a shaping tool at one end of the glass containers. In the method, dimensional data is provided for the respective glass tube and the position of the shaping tool is adjusted in a motorized manner in the axial direction (z) of the glass containers so as to correspond to the provided dimensional data for the respective glass tube.

Abstract: A method for homogenizing glass includes the method: providing a cylindrical blank composed of the glass having a cylindrical outer surface that extends along a longitudinal axis of the blank between a first end face and a second end face, forming a shear zone in the blank by softening a longitudinal section of the blank and subjecting it to a thermal-mechanical intermixing treatment, and displacing the shear zone along the longitudinal axis of the blank. The displacement of the shear zone along the longitudinal axis of the blank is superimposed by a simultaneous oscillating motion of the shear zone along the longitudinal axis of the blank. The first end of the blank is rotated at a first rotational speed and the second end of the blank is rotated at a second rotational speed. An oscillating motion of the shear zone is generated by periodically varying the first and/or second rotational speed.

Abstract: A method for homogenizing glass includes the method: providing a cylindrical blank composed of the glass having a cylindrical outer surface that extends along a longitudinal axis of the blank between a first end face and a second end face, forming a shear zone in the blank by softening a longitudinal section of the blank and subjecting it to a thermal-mechanical intermixing treatment, and displacing the shear zone along the longitudinal axis of the blank. To enable a radial mixing within the shear zone in addition to the tangential mixing with the lowest possible time and energy input, starting from this method, cylindrical sections of the blank are adjacent to the shear zone on both sides, the first cylindrical section having a first central axis and the second cylindrical section having a second central axis, the first central axis and the second central axis being temporarily non-coaxial with each other.

Abstract: A device for producing a high-purity medical glass container from a hollow cylindrical glass blank extending along an axial direction (X) and having at least one open end, wherein the glass blank has a mouldable moulded section extending in the axial direction (X) from the open end. The device comprises a first moulding tool and a second moulding tool, where the first moulding tool has a moulding pin. The moulding pin can be moved via the open end of the hollow cylindrical glass blank in the moulded section thereof along the axial direction (X), wherein the moulding pin is fixed in a fixing unit of the first moulding tool. The moulded section can be deformed by the second moulding tool in such a way that an inner surface of the moulded section is in contact with the moulding pin, whereby the moulded section forms a channel.

Abstract: Systems for producing articles from glass tube include a converter having a base with a plurality of processing stations and a turret moveable relative to the base. The turret indexes a plurality of holders for holding the glass tubes successively through the processing stations. The systems further include a gas flow system or a suction system for producing a flow of gas through the glass tube during one or more heating, forming, separating or piercing operations. The flow of gas through the glass tube produced by the gas flow system or suction system may be sufficient to evacuate or purge volatile constituents of the glass from the glass tube and/or pierce a meniscus formed on the glass tube during separation, thereby reducing the Surface Hydrolytic Response (SHR) of the interior surface of the glass tube and articles made therefrom.

Abstract: The invention relates to a method for producing glass tubes with a cross section of a noncircular form by reshaping. This method includes at least providing a glass tube, heating the glass tube, providing at least one reshaping tool, which has a forming body with a forming area for reshaping the heated glass tube, the forming body including at least one open-porous material, setting a gas pressure in the interior of the reshaping tool lower than 90 kPa, so that a negative pressure is produced on the forming area, and reshaping the heated glass tube by applying a compressive force perpendicularly to the longitudinal axis of the glass tube, the compressive force being generated by the reshaping tool and being applied to the outer surface of the glass tube, and the outer surface of the glass tube being fixed by the negative pressure.
