Induction heating

Induction heating is a process used to heat electrically conductive materials, mainly metals, by utilizing electromagnetic induction. This method involves the creation of an alternating magnetic field, which induces electric currents (known as eddy currents) within the conductive material. The resistance of the material to these currents generates heat due to the Joule heating effect.

An induction furnace is a type of electric furnace that uses electromagnetic induction to heat and melt metal. It operates based on the principle of electromagnetic induction, which was discovered by Michael Faraday. The furnace typically consists of a coil made of copper or another conductive material that generates an alternating magnetic field when an electric current passes through it. ### Key Components and Operation: 1. **Induction Coil**: The coil generates the magnetic field. It's usually water-cooled to prevent overheating.

Induction sealing is a packaging process used primarily to create airtight seals on containers, typically for products like food, beverages, pharmaceuticals, and cosmetics. The process involves the use of induction heating to melt a foil liner that is placed under the cap of a container. Here’s how it works: 1. **Foil Liner**: A foil liner, often made from aluminum, is placed under the cap of a container before it is sealed.
