Optimize glass conditioning for consistent quality and performance.

The forehearth is critical in ensuring the glass melt is conditioned to the proper temperature and homogeneity before reaching the forming. Proper feeder and forehearth control directly impacts the quality, consistency, and efficiency of glass production. This course provides the necessary knowledge to optimize glass conditioning and ensure stable operation, minimizing defects and maximizing product quality across a wide range of glass products, from containers to glass wool.


You should attend if you are interested in:

  • Principles of the feeder and forehearth syste
  • Thermal heat transfer and temperature homogeneity
  • Impact of gas heating and electrical boosting
  • Devitrification at the cold spots
  • Mixing and coloring
  • Equipment and measurement devices
  • Control and automation


What you take away:

  • Know what parameters impact the behavior to deliver a homogeneous glass at the proper temperature
  • Optimize job changes
  • Monitor feeder behavior based on available measurements
  • Recognize and take action in the event of quality issues related to the forehearth
