Abstract

A method for further processing of a glass tube semi-finished product includes: providing the glass tube semi-finished product, along with tube-specific data for the glass tube semi-finished product; reading the tube-specific data for the glass tube semi-finished product; and further processing of the glass tube semi-finished product including a step of thermal forming carried out at least in sections. At least one process parameter during the further processing of the glass tube semi-finished product including the step of thermal forming carried out at least in sections is controlled as a function of the tube-specific data for the glass tube semi-finished product. In this way, the further processing can be matched more efficiently to the particular characteristics of a glass tube semi-finished product to be processed or a particular subsection thereof, and the relevant characteristics of the particular glass tube semi-finished product do not need to be measured again.
