Claim 17:
18. The method of claim 16, further comprising:
A) providing the cone element including a specified melt channel section as a semi-finished part and the sleeve as a semi-finished part;
B) inserting a distribution insert bore and shoulders as stop surfaces and the at least one melt channel into the distributor block;
C) determining a height position and, a lateral offset of one or more melt channel(s) formed in the distributor block, with respect to at least one reference point;
D) preassembling the unit by plugging together the sleeve from A) and the cone element from A) and pressing these two parts outside the distributor block with a force so that a defined elastic expansion of the outer diameter of the sleeve is produced;
E) machining the oversize outer diameter of the sleeve to an oversize increased by the elastic expansion according to step D), relative to a dimension of the distribution insert bore, and machining an oversize stop surface of the cone element to a distance dimension between the stop surfaces of the distributor block, and introducing corresponding bores to channel sections for a melt flow in the cone element into the sleeve;
F) pushing apart the preassembled unit consisting of the cone element and the sleeve;
G) inserting the sleeve into the distribution insert bore and positioning the inserted sleeve using a positioning aid;
H) supporting the distributor block with the inserted sleeve on a flange; and
I) inserting the cone element into the sleeve and pressing in the cone element into the sleeve, so that an offset-free position of the transitions of the at least one melt channel between distributor block and sleeve and between sleeve and cone element is achieved and a surface pressure is generated in sealing surfaces between the distribution insert bore of the distributor block and the sleeve and the sleeve and the cone element.
