Method and device for laser-assisted glass molding

Der Erfindung liegt die Aufgabe zugrunde, bei der Umformung von Glasprodukten, wie etwa der Umformung von Glasrohren zu Spritzenkörpern den Justageaufwand zu verringern. Damit eine Erwärmung des Glases eines umzuformenden Glas-Vorprodukts erfolgt, wird ein Laser verwendet, welcher Licht einer Wellenlänge emittiert, für welche das Glas des Glas-Vorprodukts höchstens teiltransparent ist, so dass das Licht zumindest teilweise im Glas absorbiert wird. The invention is based on the object of reducing the adjustment effort when reshaping glass products, such as reshaping glass tubes into syringe bodies. So that the glass of a glass pre-product to be reshaped is heated, a laser is used which emits light of a wavelength for which the glass of the glass pre-product is at most partially transparent, so that the light is at least partially absorbed in the glass.
