Abstract
An injection molding hot runner manifold with a double or back-up heater, where each heater is capable of producing adequate heat to heat a melt channel zone. The first heater can work independently of the second heater. In one example, the second heater can function as a back-up in the event that the first heater fails, therefore extending the time before the mold has to undergo repairs.
