Die-cast aluminum heaters are electrically heated devices with a tubular heating element as the heating body and an aluminum alloy shell, which is formed by die casting. They are typically used at temperatures ranging from 150 to 450 degrees Celsius and are widely applicable in plastic machinery, mold heads, cable machinery, chemicals, rubber, and oil equipment.

Technical Specifications

The surface load of the cast aluminum electric heater 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 heaters with good thermal conductivity metal alloys, ensuring uniform surface temperatures and 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 saved by 35%.

Cautionary Notes

1. Aluminum die-cast electric heating coils should be properly positioned and secured. The effective heating area must be tightly adhered to the heated object, and no empty burning is allowed. If dust or contaminants are found on the surface, they should be cleaned off promptly before use to prevent affecting heat dissipation and shortening the lifespan.

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

3. The wiring section should be placed outside the heating and insulation layers, with the housing properly grounded. Avoid contact with corrosive, explosive substances, and moisture. The lead wires must 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.
