Induction hardening is a specialized heat treatment process used to increase the surface hardness and wear resistance of metal parts, primarily steel. The process involves using an induction coil to generate a magnetic field with alternating current. This magnetic field induces eddy currents on the surface of the metal, causing it to heat rapidly due to electrical resistance, while the core of the metal remains relatively cool because of the "skin effect," which concentrates the current and heating on the surface layer.

​

Once the surface of the metal reaches the desired temperature, typically between 800°C and 1000°C, it is quickly cooled using a quenching medium such as water, oil, or another suitable coolant. This rapid cooling, or quenching, transforms the heated surface layer into martensite, a very hard microstructure. As a result, the surface becomes hard and wear-resistant, while the core retains its original toughness and ductility.

Our induction hardening machine is designed to provide precise, consistent, and efficient hardening of steel components, specifically targeting applications that require controlled case depth and hardness. The advanced control system and built-in monitoring features ensure high-quality processing, while the automated component handling and quenching systems maximize productivity and reliability.
