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 molded and cast into various shapes through centrifugal casting, including round, flat, right-angle, air-cooled, water-cooled, and other special shapes. After precision processing, it can be tightly fitted with the heated object, with a surface load that can reach5-8w/cm²。
