hotspring Coil Heaters

The hot­slot is a heat­ing el­e­ment for heat­ing hot run­ner noz­zles for plas­tic in­jec­tion mold­ing. It is based on the proven tech­nol­o­gy of the “hot­spring Mi­ni” and “hot­spring Mi­cro” coiled tub­ing car­tridges, which are pressed in­to a brass car­ri­er tube.

Due to its low wall thick­ness, start­ing at 1.5 mm for the hot­slot Mi­cro, the hot­slot al­lows min­i­mum nest dis­tances. In ad­di­tion to the con­nec­tion de­signs, anal­o­gous to the hot­spring coiled tub­ing car­tridge, the course of the groove for the heater to be pressed in can al­so be in­di­vid­u­al­ly se­lect­ed for the hot­slot. The pow­er dis­tri­b­u­tion is thus ab­solute­ly pre­cise and re­pro­ducible to en­sure tar­get­ed and ho­mo­ge­neous tem­per­a­ture con­trol in the man­u­fac­tur­ing process. 

The com­bi­na­tion of brass car­ri­er and he­li­cal car­tridge al­lows for low-pow­er zones that would be in­con­ceiv­able with a sim­ple he­li­cal car­tridge. Even me­an­der wind­ings, re­cess­es, aper­tures and bores as well as de­signs as a flat plate heat­ing el­e­ment are pos­si­ble. To fa­cil­i­tate sub­se­quent dis­as­sem­bly, the car­ri­er tube can be nickel-plated.
