Hardening spring clamp

INDUCTION - Heat treatment

Induction hardening ensures a long lifespan for spring clips in their industrial applications. The key to superior strength and durability in spring clips.

Spring clips used in industrial applications are critical components that must maintain their elasticity and strength over time. Heat treatment through induction hardening is essential for increasing surface hardness and improving wear resistance, ensuring that spring clips can operate reliably under repeated loads and stressful conditions.

With induction heating, greater elasticity and strength of the spring clip are achieved, with quick and precise heating in just a few seconds.

This application involves a heat treatment process to harden a metal spring clip. The part is made from bent sheet metal, initially ductile, and through the quenching process, it gains elasticity and retains its ability to return to its original shape. The spring clip is made of AISI 420 stainless steel.

Details of heating process:

Generator used: High-frequency Platinum HF2
Power setting: 60% (about 1.2 kW)
Target temperature: 1100°C
Time required: 14 seconds

The clip was placed on a ceramic brick inside a single-turn elongated inductor for heating. The process was monitored in real-time using a temperature reader.
