An improved hot runner manifold for a multi-cavity injection molding system. The manifold is formed in a manifold block and an insert. This insert may be a round bar with an outward shape which is grooved with a flow channel, or the insert may be combined with a set of grooved round bars together with matched grooved pipes. This insert will be inserted into the bore of manifold block. This grooved insert works as a flow channel inside the manifold. Compared to the traditional manifold, this invention can easily help to produce a balanced-flow manifold which will shorten the delivery time, be produced inexpensively, provide an easier structure to make multiple-drops (such as 12, 16, 32, 64, 256 drops) in an elongated direction with a balanced flow, provide a manifold structure to help the flow channel of insert to be easily taken off for cleaning and provide a very good temperature-balance manifold in order to help molding nice quality plastic for each drop.
