An induction cooker contains a copper coil located beneath its ceramic glass surface. When the cooker is switched on, a high-frequency alternating current flows through the coil, creating a rapidly changing electromagnetic field.When cookware made from magnetic materialssuch as cast iron or magnetic stainless steelis placed on the cooking surface, the magnetic field induces eddy currents within the base of the cookware.These eddy currents generate heat through the electrical resistance of the metal, allowing the cookware to heat up rapidly while the cooktop itself remains relatively cool.In simple terms: the cookware becomes the heat sourcenot the cooktop.
In the manufacturing industry, especially for automotive and machinery components, material hardness plays a crucial role in determining product durability, wear resistance, and overall performance. Heat Treatment is a thermal process used to enhance the mechanical properties of metal components. By heating the material to a specific temperature and cooling it under controlled conditions, manufacturers can significantly improve hardness, strength, and service life.
S45C is a medium carbon steel widely used for shafts, gears, pins, rollers, and various machine components due to its excellent balance of strength and machinability.
Heat treatment and induction hardening are widely used to improve hardness, wear resistance, and service life of metal components such as shafts, gears, rollers, and machine parts.However, improper heating, excessive cooling rates, material defects, or residual stress may cause cracks during or after the hardening process. Therefore, crack inspection is a critical quality control step before parts are released for service.
What is Induction Brazing?Induction Brazing is a joining process that uses electromagnetic induction to generate heat directly within a metal component. The heat melts a filler metal, which flows into the joint by capillary action, creating a strong and reliable bond without melting the base materials.Compared with conventional flame brazing, induction brazing offers superior temperature control, faster processing times, and improved product consistency.
Induction Hardening is a heat treatment process that selectively hardens the surface of steel components by using electromagnetic induction. This process rapidly heats the surface layer of the material, followed by immediate quenching, resulting in a hard wear-resistant surface while maintaining a tough and ductile core.The achievable hardness depends on the steel grade, carbon content, alloy composition, and processing conditions.

Induction Heat Treatment, also known as Induction Hardening, is a heat treatment process that uses high-frequency electromagnetic induction to rapidly heat the surface of a metal workpiece. This process allows precise surface hardening while maintaining the core toughness of the material.
In an Induction Heating or Induction Hardening system, the Copper Coil is one of the most important components. However, another key part that significantly improves heating performance is the Ferrite Core, also known as a Magnetic Flux Concentrator.A Ferrite Core is a special magnetic material installed around the Induction Coil to help concentrate and direct the magnetic field toward the workpiece more efficiently.Examples of Ferrite Core used in Induction Heating
