Abstract: A method for shaping the mouth of a hollow precursor made of glass is provided, as well as glass produced thereby. The method includes heating the mouth of the hollow precursor; introducing a mandrel along a first direction into the mouth while the hollow precursor is rotating; and pressing shaping rollers along a second direction on an outside of the mouth while the hollow precursor is rotating with the mandrel in the mouth. The first and second directions are perpendicular to one another. The method can include moving the mandrel along second and/or third directions together or separate from expanding the mandrel along the second and third directions.

Abstract: A molding tool, a method, and an apparatus for hot forming of glass are provided that provide glass products used for pharmaceutical packaging. The molding tool includes a forming mandrel for reshaping at least a portion of a heated region of a glass precursor. The mandrel has a temperature-stable core material and an alloying element. The core material is made of precious metals, in particular of platinum group elements, and the further alloying element is made of one of tungsten, zirconium, rhodium, molybdenum, and rhenium.

Abstract: A method is provided for reshaping a glass body rotating about its longitudinal axis. The method includes using a means for establishing a temperature profile, a radial forming tool and an axial forming tool. In the method, a first temperature profile is established and the glass body is reshaped by engaging the radial forming tool. Then a second temperature profile is established and the glass body is reshaped by engaging the axial forming tool.

Abstract: A device for producing glass products for primary pharmaceutical packaging is provided. The device includes a clamping chuck for clamping a glass product, a drive for driving the clamping chuck rotatingly about a longitudinal axis thereof, and a burner for heating a glass products received within the clamping chuck. The clamping chuck has a baffle structure for generating a gas current for cooling the clamping chuck when the clamping chuck is rotatingly driven about a longitudinal axis thereof while the glass product is heated above its softening temperature for hot-forming.
