Device and method for producing glass products for primary pharmaceutical packaging
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.
