<p>An injection molding heater (38) having one or more melt bores (78) extending therethrough to be removably mounted between the melt distribution manifold (26) and each nozzle (10) in a multi-gate injection molding system. The heater (38) has a planar body (92) made of a thermally conductive material and heat is provided to it by a heating element (98) which can be electrical or a heat pipe or by a heated fluid flowing through a passage (126) in the planar body (92). Each one or more of the heaters (38) can be connected to separately controlled power sources to separately adjust the heat provided by the heaters (38).</p> |
