There are multiple options for electric heating plates

The electrothermal plate is made of stainless steel, ceramic and other materials as the outer shell. The electrothermal alloy wire is enclosed in the interior of the electrothermal plate. Therefore, it is enclosed for heating. Its heating material is electrothermal alloy wire, the principle is very simple, is the basic electrothermal effect. When working, the electric current passes through the electrothermal alloy wire, and the electrothermal alloy wire will generate heat, converting electrical energy into heat energy and transmitting it to the outer shell.

Electric heating plates can be divided into stainless steel electric heating plates, ceramic electric heating plates, and cast aluminum and copper electric heating plates, each of which has its own characteristics, among which:

1, stainless steel electric heating board: mica plate, mica sheet) heater use mica plate, mica sheet) good insulation performance and its high temperature resistance, it with mica plate (sheet) for the skeleton and insulating layer, supplemented by galvanized sheet or stainless steel plate as a support for protection, but make it plate, sheet, cylindrical, cone, cylinder, circle etc. Various type of heater. Normal surface load of 2.5-3w, temperature resistance of 500℃.

2. Ceramic electric heating board: ceramic electric heating board is widely used in light, heavy industry and household electric heating appliances due to its surface heating without charge after electrification. Ceramic package compound electric heater can be made into round rod shape, plate shape, tube shape, arc shape and other shapes. It looks and feels like ordinary daily porcelain, but it is embedded with electric heating wire. Due to the ceramic material has a good electrical insulation performance at the working temperature, so the surface does not live, the leakage current is small, safe and reliable.

3, cast aluminum, cast copper electric heating plate: cast aluminum, cast copper electric heating plate can be divided into die casting and casting casting, in the case of more specifications, size, the general use of casting technology. High purity aluminum blocks and copper blocks are used in casting production, which are changed from solid to liquid state by high temperature furnace, and then injected into the mold which has already been installed with heating tube, which is cooled and formed, and then processed into fine processing.
