Cast aluminum electric heaters are heated by tubular electric heating elements, which are bent and shaped, then entered into molds for centrifugal casting into various shapes such as round, flat, right-angled, air-cooled, water-cooled, and other non-standard shapes. After precision processing, they can be tightly fitted to the heated object, with a surface finish that meets the required standards.3-4.5w/cm² The product heats up quickly, distributes heat evenly, has excellent thermal conductivity, and boasts a long service life, making it one of the more rational heaters on the domestic and international markets.
