Non-swaged cartridge heaters offer a cost effective solution where the performance of a swaged heater is not required. Non-swaged heaters can be used at watt densities up to 45 watts per square inch and temperatures up to 1000°F. Non-swaged heaters offer tighter length tolerances than swaged heaters. Non-swaged heaters can be built with 3 independent heat zones. Non-swaged heaters are not recommended for applications where there is a lot of vibration or impact.

Non-swaged heaters offer tighter length tolerances than swaged heaters, making them ideal for applications such as platens where heaters are generally longer. Non-swaged heaters are not recommended for applications where there is is a lot of vibration or impact.
Most of the lead configurations and options available for swaged HotRod heaters are also available for non-swaged cartridge heaters. Our standard options are listed below.

Watt density is calculated with the following formula:
Watt Density = Wattage / Heated Length x Diameter x 3.14
Clearance is determined by taking the hole diameter and subtracting the heater diameter.
