Originally designed to perform the pre-inoculation operation for gray iron, this equipment has been successfully positioned and proven ideal for other metallurgical applications, particularly useful in the production of ductile iron.


Equipment designed to inject granular FeSi or other additives into liquid iron during the pouring operation or during the transfer of liquid metal into the pouring system.

The equipment accurately and reliably distributes the material to be injected from a distance of up to 40 m, making it particularly adaptable to foundry conditions where space/access around the melting furnace or pouring system is limited.

Dosage is controlled through the weighing system interfaced with the renowned Progelta control system. The user controls the automatic additive process through parameter settings and programmable material quantities.

Every operation, including alarms, is recorded in the database and is part of the production log, useful for quality control and exportable production reports.

  • Material and equipment at a convenient site away from the production line
  • Reduced handling: material taken directly from the big bag (super sack)
  • Material is protected from contamination and oxidation
  • Reduced human error: automatic, recorded, and reliable operation
  • Injection (with pneumatic motor) synchronized with the iron flow
  • User control: programmable settings and quantities
  • High-performance diagnostic tools; real-time feedback for quick response times
  • Complete production records, traceable, exportable
