Cast aluminum heaters are electrically heated devices with a tubular heating element as the heat source, encased in an aluminum alloy shell formed through die casting. They operate at temperatures typically ranging from 150 to 450 degrees Celsius and are widely used in plastic machinery, mold heads, cable machinery, chemicals, rubber, and oil equipment.

Technical Specifications

Cast aluminum electric heater surface load can reach 2.5-4.5 W/cm², with operating temperatures between 300-450°C.

2. Cast aluminum heaters are highly efficient and evenly distributed in heat, featuring excellent heat-conducting metal alloys that ensure uniform surface temperatures, eliminating hot and cold spots in equipment. They boast long lifespan, good thermal insulation, strong mechanical properties, corrosion resistance, and magnetic resistance. By adding thermal insulation to the outer heat-dissipating surface and sintering infrared rays on the inner surface, energy consumption can be reduced by 35%.

Cautionary Notes

1. Aluminum casting electric heating coils should be properly positioned and secured. The effective heating area must be tightly sealed to the heated object, and burning in the air is strictly prohibited. In case of dust or contaminants on the surface, they should be cleaned thoroughly before use to prevent heat dissipation and extend the service life.

2. Magnesium oxide powder at the outlet end of the electric heating tube should be kept free from contaminants and moisture intrusion at the usage site to prevent electrical leakage accidents.

3. The wiring section should be placed outside of the heating and insulation layers; the housing should be effectively grounded. Avoid contact with corrosive, explosive substances, moisture; the lead wires should be able to withstand the temperature and heating load of the wiring section for a long time, and excessive force should be avoided when tightening the wiring screws.
