In many applications the use of electrical heating has advantages over fuel-fired alternatives: Feeder channels utilising immersed electrodes allow a covered gas surface thus eliminating problems due to evaporation of volatiles such a lead or boron compounds; electrically heated gathering bays allow the use of robots or manual gathering of lead glass with reduced surface cord; platinum down-draws provide glass of superior homogeneity.

Spout heating
Fives Stein Mixed-melt furnaces with PENELECTRO technology offer the possibility and advantages of electric melting in situations where cold-top operation is not possible due to high-gassing of melting reactions (e.g. carbon-sulphur amber), or when increased output flexibility is required.
Applications:
High quality soda-lime (tableware)
Pharmaceutical
Lead crystal
Technical and ophthalmic
Tailored innovative Products and systems
Fives Stein offers a range of innovative products and systems – tailored to suit a particular process application, or to solve a particular problem. For example forehearth channel electric boosting can be installed to increase temperature and chemical homogeneity in the final gob (particularly critical in large items such as blocks and HV insulators); working end boosting to increase channel entry temperature, or to supplement gas combustion.
