A glass tube forming device adapted to be used in a forming machine of glass containers for medical use includes a parallelepiped base block supporting a pair of arms each bearing a flat roller or idle deforming disc. The arms are L-shaped and are arranged in the upper part of the base block, and can be moved closer to, and farther away from, each other to be arranged to respectively engage on and disengage from a glass tube to be shaped. The deforming disc hangs from the free end of each arm and placed idle underneath the respective arm. Each arm has channels for oil and ducts for cooling air therein, ending at and above each deforming disc.

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.
