A mini coil heater from Durex Industries uses a unique clamping band keep the heating element at full clamping force at elevated temperatures. Unlike conventional cam-locking designs, this wedge-locking mechanism compensates for thermal expansion.

The tubular heating element is constructed in a rectangular profile to increase surface contact between the heater and the injection nozzle, resulting in more efficient heat transfer.
