1. Stainless steel electric heating plate (mica electric heating plate)
2. Ceramic electric heating plate
3. Cast aluminum electric heating plate
4. Cast copper electric heating plate The ceramic electric heating plate heats up on the surface after being energized without being charged. It is widely used in light and heavy industries and household electric heating appliances. The ceramic-clad electric heater can be made into various shapes such as round rod, plate, tube, arc and other shapes. Its appearance and texture are like ordinary daily-use porcelain, but there are electric heating wires embedded in it.
Since the ceramic material used has good electrical insulation performance at working temperature, the surface is not charged, the leakage current is small during work, and the use is safe and reliable. Cast aluminum and cast copper electric heating plates can be divided into die-casting and cast-casting. Generally, the casting process is adopted for the occasions with more specifications and sizes. In casting production, high-purity aluminum and copper blocks are used, which are changed from solid to liquid in a high-temperature furnace, and then injected into a mold that has a heating tube installed, cooled and molded, and then refined.
