Our proprietary " rubber coil " can adjust to various work pieces with varying hardening lengths. Rubber coils can heat different work pieces with differing hardening widths on one machine using one single-shot coil. The traditional scanning method was affected by factors such as process time and required high investment costs.
However, Fuji Denshi's " rubber coils " provide a solution to these shortfalls and allows for a simple transition.
Furthermore, this system results in the formation of an even hardening layer and low distortion which contributes to a dramatic increase in production rates, thereby harnessing the inherent strengths of induction hardening.
