Cast In Aluminum Heaters For Packaging Machinery




The cast in heaters are composed of one or more electrical heating elements embedded in an aluminum alloy, brass, bronze, copper-nickel or iron type material with excellent thermal conductivity.
The gravity casting provides excellent homogeneity of the casting material and therefore allows excellent thermal diffusion. The regularity of the surface temperature is ensured by a suitable forming. The cast heating elements can be used to surface temperatures up to 950 ° C.
Aluminum alloy is the most commonly used material up to a temperature of 400 ° C. For higher temperatures, or because of mechanical stress or specific environmental constraints, it is replaced by alloys of brass, bronze or cast iron.
The cast in heating devices are machined according to drawings taking into account roughness requirements.
