The aluminum casting heater is an electric heater with a tubular electric heating element as the heat source, encased in an aluminum alloy material shell, formed by die casting. The operating temperature typically ranges from 150 to 450 degrees Celsius and is widely used in equipment such as plastic machinery, mold heads, cable machinery, chemicals, rubber, and oil.

Technical Specifications

Cast aluminum electric heater surface loading 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 thermal conductivity metal alloys that ensure uniform surface temperatures, eliminating hot and cold spots on the equipment. They offer long service life, good thermal insulation, strong mechanical properties, corrosion resistance, and magnetic resistance. By adding insulation to the external heat dissipating surface and applying infrared烧结 to the internal surface, energy consumption can be reduced by 35%.

Cautionary Notes

1. Aluminum cast electric heating coils should be properly positioned and secured. The effective heating area must be tightly sealed against the heated object, and no open burning is allowed. In case of dust or contaminants on the surface, they should be cleaned promptly before use to prevent heat dissipation issues and prolong the lifespan.

2. Magnesium oxide powder at the outlet end of the electric heating tube; prevent pollutants and moisture from seeping in at the usage site to avoid 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, 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.
