Coil heaters are designed to melt plastic in hot runner molds. The coil heater design allows for heat transfer in a 360 Degree area allowing for optimum heat transfer inside the mold. In order for the Coil heater to get it’s spring shape it is heated and then slowly cooled to allow for it to be molded and shaped. Although there is some spring back that occurs it is usually only .001-.002″ and can be corrected by shaping it to an undersized mandrel. These heaters can allow up to 106 Watts per square inch and can reach operating temperatures of 1200 Degrees Fahrenheit or around 649 Degrees Celsius.
