State of the art clamping mechanisms to ensure the tightness of a GC-coil coil heater on the hot runner nozzle, there are many. But in practice, most come very quickly reach their limits: the material loses its strength under temperature, expands and the coil heater rises uncontrollably from the nozzle from. This results in air cushion between the heating element and nozzle make an even temperature control impossible and also perform overheat very quickly to the complete failure of the coil heater. In addition, many clamping mechanisms require a lot of space by screw, clamps or by the complete pouring of the heating element, which is not in common hot runner molds with low Kavitätsabständen available.
The GC-jacket seals and clamps permanently. The GC-jacket is, in simple terms, a slotted, tubular curved special sheet which the GC-coil coil heater fixed to the cylindrical hot runner nozzle spans at temperatures up to 550 ° C. The material properties of GC-jacket in combination with the thin-walled structure easily and efficiently solve all the problems of conventional clamping mechanisms.
