Stoelzle Glass Group has announced a major investment in its Heřmanova Huť production facility in the Czech Republic, aimed at strengthening the supply of pharmaceutical glass packaging across Europe. The project includes a complete rebuild of the site’s amber glass furnace alongside upgrades to forming, inspection and packaging technologies to improve production capacity, energy efficiency and operational reliability.

Construction is scheduled to begin in August 2026, with the furnace rebuild taking approximately 65 days. Production is expected to resume in October 2026. The new end-port furnace will feature fully rebuilt forehearths and regenerators, a larger melting area and double the electrical boosting capacity, enabling higher output while reducing specific CO₂ emissions per tonne of glass melted.

In addition to the furnace, Stoelzle will modernise downstream production through investments in glass distribution systems, IS forming equipment, cold-end inspection technology and automated packaging. These upgrades are designed to improve manufacturing efficiency, process stability and the consistent quality required for pharmaceutical glass containers.

The project brings together leading industry suppliers, including HORN for the furnace, Interprojekt for the ESP filter, Bucher Emhart Glass for the IS machine, MORAVIA GLASS TECHNOLOGY, Heye International and Iris Inspection Machines for cold-end equipment, and B&B for packaging systems.
