Batch Automatic Lines

Batch automatic lines represent Gadda’s core business. Each line could include: austenitizing and tempering batch furnaces, quenching tanks, loading/unloading machines, cooling stations, storage stations and handling equipment.

Heat treatment lines are fully automatic, all processes are controlled by the computerized control systems and with adequate storage stations, customers can perform continuous production without supervision or during weekends. Projects are tailored to best satisfy customers requirements.

Typical materials treated are: bars, alloyed steel pipes, fittings, forged or cast pieces. Batch lines are very flexible and cover almost any executable thermal treatment. A modular approach allows future expansion to accommodate incremented productivity needs.
