Electric Die Cast Aluminum Heater For Plastic Extrusion Machine /
Injection Molding
1. Description
The cast in heaters is one kind of electric heating element , which
are comprised of one or more electrical heating elements embedded
in alloy such as Aluminum or Bronze with good thermal conductivity.
The homogeneity of the casting material enables excellent thermal
diffusion. The uniformity of the surface temperature is ensured by
a suitable forming. The cast heating elements can be used to
surface temperatures up to 950 ° C.
Cast in aluminum heaters
Aluminum alloy is the most commonly used material up to a
temperature of 400 ° C. For higher temperatures, or due to
mechanical stress or other specific environmental constraints, it
can be substituted by alloys of brass, bronze or cast iron.
