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