The invention relates to a method for arranging at least one through-channel in a solid body,e.g. a hot runner. The invention has for its object to offer a method of the type described, using which a considerable improvement can be achieved in the quality of high grade injection moulded products. To this end the method comprises the following steps: (1) the providing of at least two solid blocks which are together sufficiently large to form the body, (2) complementary modelling where required of corresponding side faces of the blocks, (3) the forming of a groove in each of the said side faces, which pairs of grooves possess corresponding forms, (4) the placing against each other of the said side faces such that the grooves together bound a channel, and (5) the coupling of the blocks into a body. This method is preferably succeeded by the following step: (6) the passing of a liquid abrasive agent with force through the channel for a certain period of time in order to render the channel a desired rheological form through honing, which honing may be pulsating.
