HORN Glass Industries AG, a German specialist in the design and supply of complete glass melting technology is a solution partner for the worldwide glass industry. 

At its location in Plößberg, Germany, HORN Glass Industries AG plans and makes glass melting technology and turn-key projects for the float and container glass industry. The high-performance glass melting furnaces and turn-key projects go to glass manufacturers all over the world and serve the production of beverage bottles, food containers, drinking glasses, glass panes, glass tubes, glass fibers or special glass.

With more than 135 years of experience, HORN has been the specialist and expert in the field of the construction of glass melting furnaces for many years. However, since many years this has changed and HORN is now one of the industry leaders in the implementation of turn-key projects.

Subsidiary companies in China, Malaysia, India, Croatia, Ukraine, Brazil and the Czech Republic add value to the global customers. So, HORN offers customer proximity and short response time in the global market. Almost 90% of the products are exported from Plößberg in Upper Palatinate to more than 75 countries worldwide.


Melting Furnace - Float glass furnace
High furnace capacity up to 1200 t/d, high quality glass for architecture or automotive purpose, low energy consumption, low emmission values.

Float glass manufacturing is not like the manufacturing of commodities like steel or plastic. Each of the production processes requires raw materials to be weighed, mixed, melted at high temperatures, formed into continuous ribbons, cooled and cut into a size that fits its use.

The melting furnace consists of refractory bricks and special shapes, support and binding steel, insulation, a fossil fuel firing system, temperature sensors and a computerized process control system. The furnace is carefully designed to meet the plant's specific gross daily glass production tonnage goals.

The insulation, special airflow features, and combustion air heating enable the furnace to operate at maximum fuel efficiency with negligible pollutant emissions. The furnace is sized and designed to provide high quality glass with the smallest amount of energy per ton of glass melted.

The float glass furnace can be operated with natural gas, LPG, biogas and oil. Additionally there is the possibility to install specially developed melting assistant devices like electrical boosting or bubbling systems.
