We are actively working on shaft hardening using line coils and have gathered a wealth of practical know-how, including support rollers.
Order Equipment With the semi-open coil, an ideal hardened layer can be achieved even for complex shapes and stepped parts. In single-shot hardening, uniform compressive residual stress occurs on the surface, significantly improving the mechanical properties of the workpiece itself, such as fatigue strength and torsional strength. By consolidating the development and manufacturing technology of line coils suitable for the complex shapes of multi-stage shaft workpieces, we have successfully realized simultaneous hardening of long materials for the first time. It demonstrates performance that surpasses conventional moving hardening in terms of hardening strength, uniformity of hardening, and energy savings. ★ For inquiries by phone, please contact us here: Osaka Headquarters → TEL: 072-991-1361 Nagoya → TEL: 052-322-1361 Tokyo → TEL: 03-5472-1361 *When calling, please mention "Ipros" as a reference.

basic information
At Fuji Electric Industry, which has always been at the forefront of heat treatment technology, we have conducted extensive research on induction heating (IH) to achieve quenching with higher precision, greater strength, and excellent environmental benefits. We refer to this technology as "precision hardening," signifying a high-class quenching process unlike any before.

Company information
We are developing a variety of devices necessary for "precision hardening," based on the development of semi-open coils, including cooling systems for processed parts, inverters for heating power supplies, and chiller units for cooling inverters. Additionally, we respond to requests for custom-made devices and systems that realize "precision hardening" tailored to our customers' production environments. We support our customers' production with 'FD-ioT,' which enables "visualization of operational status," "remote support," and "preventive maintenance" for quenching equipment.
