Heating Equipment
Casting heater is a tubular electric heating element as the heating body, after bending forming, in accordance with customer requirements to design the mold, the curved heating tube into the mold with metal alloy material as the shell to centrifugal casting into the shape required by customers, such as: round, right Angle, air cooled, water cooled and other shapes and so on.

Features and Applications:
After finishing, it will be closely fitted with the heated body, the surface load of the cast aluminum electric heater can reach 2.5-4.5w/c㎡, and the working temperature range is generally between 0-350℃; The surface load of the cast copper electric heater can reach 3.5-5.0w/c㎡, and the working temperature range is generally between 0-800℃; The surface load of the cast iron electric heater can reach 4.5-6.0w/c㎡, and the working temperature range is generally between 0-750℃. Casting electric heater is a kind of evenly divided heater, which has the advantages of good insulation performance, strong mechanical properties, corrosion resistance, magnetic field resistance and so on. The heat preservation device is added to the external heat dissipation surface, and the infrared ray is sintered on the internal heat dissipation surface, which can save electricity.
Casting electric heater is suitable for all major industries, it is widely used in plastic machinery, mold, cable machinery, alloy die-casting machine, pipeline, chemical industry, rubber, petroleum and other industries.
