Cast copper electric heaters are suitable for high-temperature heating. This product uses tubular electric heating elements as the heating source, which are bent and shaped, then cast into various shapes using centrifugal casting in molds, including circular, flat, right-angled, air-cooled, water-cooled, and other special shapes. After precision processing, it can be tightly fitted to the heated object, with a surface load that can reach5-8w/cm²。
