A muffle for a glass tube forming process includes an inlet end coupled to a bowl, an outlet end having an inner dimension larger than an inner dimension of the inlet end, and a sidewall extending from inlet end to the outlet end. A radial distance from a center axis of the muffle to an inner surface of the sidewall increases from the inlet end to the outlet end and the sidewall is substantially free of abrupt changes in the radial distance that produce instability regions within the muffle. The muffle includes a channel between an outer surface of a portion of the sidewall and an insulating layer disposed about the sidewall, the channel being operable to pass a heat transfer fluid into thermal communication with the sidewall to provide cooling to the muffle. Glass forming systems including the muffle and glass tube forming processes are also disclosed.

A mold includes a mold component, a plurality of ejector pins and a stop block. The mold component has a molding surface for forming a glass product and a bottom surface disposed opposite to the molding surface. The mold component defines a plurality of passing through holes through the molding surface and the bottom surface. Each ejector pin passes movably through one corresponding through hole and is configured to separate the glass product from the mold component. The stop block for forming a stop on the ejector pins disposed on one side of the bottom surface. Separates the glass product from the mold component before the glass product is completely cooled down by using the combination of the ejector pins together with the stop block, which can make the cooling of the glass product more uniform.

Provided is a method for manufacturing a glass container with which a glass container having a distinctively shaped inner space and excellent aesthetic appearance can be manufactured in good yield. The method for manufacturing a glass container includes steps (A) to (E). (A) A step of introducing a gob into a mold through a funnel. (B) A step of blowing air into the mold through the funnel, bringing a plunger disposed on a side opposite the side to which the funnel is fitted in contact with the gob, separating the plunger from the gob, and forming a recess on the surface of the gob. (C) A step of removing the funnel from the mold and fitting a baffle to the mold. (D) A step of blowing air from the plunger, and forming an inner space inside the gob with the recess as a starting point while simultaneously forming an outer shape by pressing the outer side of the gob to a molding surface of the mold to obtain a glass container of the final shape. (E) A step of transferring the glass container of the final shape to a cooling mold and cooling the same.

An apparatus for the automated production of glass assemblies comprises: a turning machine with at least two spindles which are rotatable about a common axis of rotation and which each have a workpiece holder, wherein the workpiece holders are arranged opposite one another; one or more gas burners or lasers fixed on a first tool carriage which is movable in parallel and/or perpendicularly to the axis of rotation; one or more drives for driving a rotational movement of the spindles and a movement of the first tool carriage; a pressure module including a pump device at least one working cylinder for applying a pressure to an inner tube and/or to a space between the inner tube and an outer tube; and a control unit configured to control the burners or lasers, one or more drives, the first tool carriage and the pressure module.

A process for producing glass bottles with shoulders includes a preform preparation step and a finishing step, in which a compressed gas is blown and the preform is rotated by 180 between the preform mold and the finishing mould. Preform preparation is achieved by introducing a glass gob into the mold through an upper aperture; inserting a blowing sleeve into the glass gob, the end of the sleeve extending beyond the shoulders of the outline of the preform of the bottle, the sleeve being closed by a plunger element slidable within its interior; opening the cavity of the sleeve to disengage the plunger element; and blowing air through the sleeve, wherein the final finishing step is achieved in an open preform mold, the volume of the cavity of the finishing mold being greater than the volume of the cavity of the preform mold by 5-20%.

The disclosure relates to a method for controlling a glass sheet heating furnace using information describing a glass load including a plurality of glass sheets. The method includes transporting the glass sheets toward a heating furnace, before thermal treatment, photographing the glass load by a camera to obtain a camera image, sending first information of the camera image to a computer, on the basis of which the computer determines a first value of a dimension of the glass load and selects a value of at least one adjustment parameter of the heating furnace on the basis of the first value before the glass load has been transferred into the heating furnace, and reading second information by a line scanner, which is sent to the computer, on the basis of which the computer determines a second value of the dimension of the glass load.

For the monitoring of the application of a vacuum to the finished moulds (1, 2) of a glass moulding machine, in particular of an I. S. machine, an arrangement is proposed which is composed of a vacuum sensor (13, 14), which vacuum sensor is arranged in a vacuum line (5, 6) which charges the finished mould (1, 2) and which vacuum sensor is designed for pressure measurement and detects a pressure value, which pressure value is transmitted by way of a microcontroller (15, 16) of an I.
