Cast-In Cross Head Die Heater Manufacturer

Standard Lead Times


Extrusion Cross Head and related extrusion dies present extremely
challenging operating parameters to most conventional heating elements.
This is primarily due to the presence of excessive contamination,
high watt densities and high temperature as well as unusual
physical and dimensional requirements.
Many processors continue to use ceramic and mica band heaters on
this application, with frequently marginal results. In these instances,
Cast-In Aluminum or Bronze heaters are recommended to substantially
improve heater life expectancy and performance.
Cast-In Heaters are less susceptible to contamination problems,
and can operate at higher temperatures with higher watt densities.
In addition, the design is structurally better suited to accommodate
holes and cutouts without compromising the heater’s electrical and
mechanical integrity.

As a standard, Cross Head Die Heaters are typically designed in aluminum as a one-piece band with a single slot that
can be slid over the die and clamped with stainless steel clamping straps. For higher temperature or high watt density
requirements, bronze or brass alloys can be used.
