Die-cast aluminum heaters are electric heating elements with tubular heating elements as the heat source, encased in aluminum alloy material, formed by 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 heaters can achieve a surface load of 2.5-4.5 W/cm², with operating temperatures between 300-450°C.

2. Cast aluminum heaters are highly efficient and evenly distributed heat sources, featuring good thermal conductivity metal alloys that ensure uniform surface temperatures, eliminating hot and cold spots on the equipment. They offer long lifespan, excellent insulation properties, strong mechanical performance, corrosion resistance, and magnetic resistance. By adding insulation to the external heat dissipation surface and infrared烧结 to the internal heat dissipation surface, electricity 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 bonded 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 issues and extend the lifespan.

2. Magnesium oxide powder at the electrical heating tube's outlet end should be protected from pollutants and moisture intrusion at the usage site to prevent electric 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, and moisture. The lead wires should be able to withstand the temperature and heating load of the wiring section for a long time; avoid excessive force when tightening the wiring screws.
