When electromagnetic heaters are used for electroplating heating, they use the principle of electromagnetic induction to convert electrical energy into thermal energy, which is transferred to the electroplating solution or plating carrier, thus achieving the purpose of heating.

Electromagnetic heaters typically consist of the following components:

1. High frequency power supply: Provide high-frequency electrical energy required for electromagnetic fields.

2. Coil: The electrical energy provided by a high-frequency power source forms a high-frequency alternating magnetic field.

3. Heating area: The part that needs to be heated in the electroplating process can be the plating solution or plating carrier in the electroplating tank.

The working principle is as follows:

• A high-frequency power supply provides electrical energy and converts it into high-frequency current.

• High frequency current passes through the coil, forming a high-frequency alternating magnetic field.

• The high-frequency alternating magnetic field penetrates into the heating area, such as the electroplating solution or carrier in the electroplating tank.

• Electrical conductors (such as metals) in electroplating solutions or carriers are affected by high-frequency alternating magnetic fields, where electrons are subjected to magnetic field forces, rapidly vibrating and generating friction.

• The heat generated by friction will heat the plating solution or plating carrier and transfer it to the object that needs to be heated (such as electroplating parts).

• In this way, the electromagnetic heater converts electrical energy into thermal energy, achieving heating of the plating solution or plating carrier.

By controlling the output power and working frequency of the high-frequency power supply, precise control and adjustment of the heating process can be achieved to meet the temperature requirements in the electroplating process.

In short, the electromagnetic heater utilizes the principle of electromagnetic induction to generate alternating magnetic fields in the coil through high-frequency current, which then transfers heat energy to the plating solution or plating carrier, achieving control and regulation of electroplating heating.
