Copper casting electric heaters are suitable for high-temperature heating. This product uses a tubular electric heating element as the heat source, which is bent and shaped, then molded into various forms through centrifugal casting, including circular, flat, right-angle, air-cooled, water-cooled, and other non-standard shapes. After precision processing, it can fit closely with the heated object, and the surface load can reach5-8w/cm²。
