Large continuous furnaces for heat treatment of springs

Agibi Progetti is an Italy-based company with long-standing experience in the design and manufacture of industrial heat treatment systems. Among its core solutions are continuous furnaces developed to support large production volumes, specifically engineered to meet the demanding requirements of spring manufacturers.

In high-intensity production environments—such as quenching, tempering, and stabilization lines—large continuous furnaces are often a necessary choice to guarantee production continuity, stable process conditions, and high throughput.

An example of an Agibi continuous furnace designed for high-volume spring production can be seen in the following video:

Energy efficiency in large-scale installations

Large continuous furnaces operate with high installed power and, if not properly engineered, can result in excessive energy consumption. Agibi’s design approach addresses this challenge through a combination of robust construction quality and targeted technical solutions aimed at minimizing thermal losses.

Optimized air circulation and heat flow management, together with the use of high-performance insulating materials, allow these systems to maintain high efficiency levels even during continuous operation and under heavy thermal loads. This translates into reduced operating costs and improved sustainability for large-scale spring production.

Temperature uniformity and process reliability

In continuous furnaces for spring heat treatment, temperature uniformity is a critical parameter. Thermal gradients inside the chamber can negatively affect the mechanical properties of the springs, compromising hardness, fatigue resistance, and overall repeatability of the process.

Agibi furnaces are designed to ensure homogeneous temperature distribution across the entire usable volume. This guarantees stable and repeatable heat treatment cycles, in line with the most stringent quality standards required by modern spring manufacturers.

Custom solutions for modern spring manufacturers

Ongoing research and development enable Agibi Progetti to deliver customized furnace solutions tailored to production volumes, work cycles, and specific plant layouts. Each system is engineered to combine process precision, optimized energy consumption, and long-term operational reliability.

With Agibi Progetti, even large-scale spring production can rely on high-performance continuous furnaces designed to handle the most demanding heat treatment processes. For further information, readers are invited to contact the company using the details provided on this page.
