Melting department with electric induction furnaces

 The melting department with electric induction furnaces represents the heart of production at the Fonderia Quaglia & Colombo in Legnano (MI). Since 1974, the company has chosen to exclusively adopt this technology, orienting its operations toward a controlled, repeatable melting process consistent with high metallurgical standards.

This choice allows the production of cast irons with a defined chemical composition, responding to the needs of industrial sectors that require precision, reliability and consistent quality.


The organization of the casting department is designed to ensure production process stability and precise control of every casting phase, from raw material selection to the pouring of the molten metal. The use of electric induction furnaces allows for efficient operations, reducing the variables typical of traditional systems and ensuring optimal temperature and alloy management.

Technology of the casting department

The melting department, with electric induction furnaces, uses a technology that melts cast iron through electromagnetic fields, avoiding direct contact with ignition sources. This approach allows for clean and controlled melting, with direct benefits for the metallurgical quality of the resulting material.


 The Fonderia Quaglia & Colombo uses two electric induction furnaces, 5 tonnes and 15 tonnes respectively, which operate synergistically to meet different production volumes.

This configuration allows for flexible order management and efficient planning of casting cycles, while maintaining the chemical characteristics of the cast iron constant.

  • Checking the chemical composition of cast iron

    One of the key aspects of the melting department with electric induction furnaces is the control of chemical analysis. The technology used allows for precise adjustments to the composition of the molten metal, adjusting the alloying elements according to specific requirements. This level of control is essential for the production of cast iron intended for mechanical processing and industrial applications, where stable mechanical and structural properties are essential. The melting process is constantly monitored to ensure uniformity between different castings and production continuity over time.

  • Production capacity and department organization

    Thanks to its equipment and internal organization, the casting department has an annual production capacity of approximately 4,000 tons of cast iron. This capacity allows for continuous production while maintaining high levels of process control and traceability. The entire department is structured to integrate with the foundry's subsequent processing phases, ensuring a coherent and well-coordinated production flow. Melting times, pours, and temperatures are carefully planned to ensure operational efficiency and consistent quality.

  • Advantages of melting with electric induction furnaces

  • The exclusive use of electric induction furnaces in the melting shop offers several concrete advantages:
  • greater precision in metal temperature control
  • stable chemical composition of the cast iron
  • repeatability of the production process
  • reduction of impurities during melting
  • efficient integration with the forming and casting shops. These elements make the melting shop a point of reference for productions requiring technical reliability and consistent production standards.
