Copper casting electric heaters are suitable for high-temperature heating. This product utilizes a tubular electric heating element as the heating source, which is bent and shaped, then molded and centrifugally cast into various forms such as circular, flat, right-angle, 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。
