The cast aluminum heater is made of tubular electric heating elements as the heating element, which are reasonably bent and formed. After entering the mold, high-quality aluminum alloy is cast into various shapes including flat plates, disks, right angle shapes, internal and external air ducts for water cooling, and other special-shaped shapes. After precision machining, the surface of the cast aluminum heater is smooth and free of casting defects, and can closely adhere to the heated object.
