No two automotive parts are the same, which is why custom coil design is the backbone of successful induction hardening. Whether it is a complex steering rack or a simple bolt, the induction coil must be shaped to follow the geometry of the part perfectly. This ensures uniform heating and prevents "soft spots" that could lead to failure. High-end providers of induction hardening for automotive industry services offer bespoke coil engineering to maximize efficiency.
