Abstract
The present disclosure relates to a method for manufacturing a hollow glass item and, specifically, to a method for manufacturing an item made of hollow pressed glass. The method includes a step of depositing at least one drop of molten glass into a mold intended for modelling a predetermined outer shape of the glass item to be manufactured; a step of pressing the molten glass into the mold by a shaping punch in order to shape the hollow glass item by hollowing out an inside space; a step of marking the glass item with a marking tool which is independent from the shaping punch, in order to imprint at least one raised and/or recessed pattern in the inside space of the glass item; a step of cooling the marked, pressed glass item; and a step of removing the glass item from the mold.
Claims11
A manufacturing process of at least one item made of pressed hollow glass, the manufacturing process consisting of:
- depositing at least one drop of molten glass into a mold configured to model a predetermined outer shape of the at least one hollow glass item;
- pressing the at least one drop of molten glass against the mold by a forming punch such that an inner volume of the at least one hollow glass item is hollowed out and forms a final overall shape;
- marking the at least one hollow glass item by a marking tool independent of the forming punch and operable to print at least one of a relief pattern and a recessed pattern on an inner surface of the at least one hollow glass item;
- cooling the at least one hollow glass item;
- and
- demolding the at least one hollow glass item.
