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